Method for determining network address and related equipment

Abstract

The embodiment of the invention provides a method for determining a network address and related equipment. The method comprises the following steps: determining an internet protocol IP address of a first node according to position identification information of a first position where the first node is located; and sending the IP address of the first node to the first node. The difficulty of acquiring the position identification information of the position of each node is low, so that the difficulty of determining the network address of the node can be reduced. In addition, resources needed for storing the position identification information are few. Meanwhile, after the node at each position is replaced, the IP address of the newly replaced node at the position can be directly determined according to the position because the corresponding relationship exists between the IP address and the position, and manual configuration or maintenance is not needed, so that the difficulty of determining the IP address of the node can be reduced, and the efficiency of determining the IP address of the node can be improved.

Description

Technical Field

[0001] Embodiments of the present application relate to the computer field, and more specifically, to a method for determining a network address, a device for determining a network address, a system for determining a network address, a chip system, and a computer-readable storage medium. Background Art

[0002] Generally, a data center includes a large number of management units, computing nodes, and switching nodes, and an Internet Protocol (IP) address needs to be allocated to each management unit, computing node, or switching node for management or network communication. The current methods for allocating IP addresses include manual allocation or automatic allocation through the dynamic host configuration protocol (DHCP). The manual allocation method requires manual allocation of IP addresses for each node. The method of automatic allocation through DHCP requires obtaining the serial number (SN) and / or media access control (MAC) address of each node, so as to allocate an IP address to each node through a device deployed with a DHCP server. However, the manual allocation method requires a lot of manpower and the efficiency of determining the IP address is low. The method of automatic allocation through DHCP requires querying the SN and / or MAC address of each node. Since the SN and / or MAC address of each node is an unordered number of more than 12 or 20 digits, the acquisition process is relatively cumbersome and requires a large amount of storage resources. In addition, with the improvement of the integration of equipment, the difficulty of obtaining the SN and / or MAC address of the node is also gradually increasing. Meanwhile, after the node is replaced, the IP address of the new node needs to be manually configured, or the mapping relationship between the SN and / or MAC address of the new node and the IP address needs to be manually modified and maintained on the DHCP server, which is inefficient.

[0003] Therefore, how to determine the network address of a node and reduce the difficulty of determining the network address of a node becomes an urgent problem to be solved. Summary of the invention

[0004] Embodiments of the present application provide a method for determining a network address, a device for determining a network address, a system for determining a network address, a chip system, and a computer-readable storage medium, which can determine the network address of a node and reduce the difficulty of determining the network address of a node.

[0005] In a first aspect, a method for determining a network address is provided. The method is performed by an operation and maintenance unit, and includes: determining an Internet Protocol IP address of a first node according to location identification information of a first location where a first node is located; and sending the IP address of the first node to the first node.

[0006] The first node is managed by a first management unit. The operation and maintenance unit and the first management unit are located in the same device or in different devices.

[0007] In an embodiment of the present application, the operation and maintenance unit can determine the IP address of each node according to the location of each node. Since it is relatively easy to obtain the location identification information of each node, the difficulty of determining the network address of the node can be reduced. In addition, fewer resources are required to store the location identification information. At the same time, after the node at each location is replaced, since there is a corresponding relationship between the IP address and the location, the newly replaced node at the location can directly determine the IP address according to the location without manual configuration or maintenance, thereby reducing the difficulty of determining the IP address of the newly replaced node and improving the efficiency of determining the IP address of the newly replaced node.

[0066] Figure 2 This is another possible schematic architecture diagram of the system for determining a network address provided in an embodiment of the present application. Figure 2 The system for determining a network address in the embodiment includes an operation and maintenance unit 210, a first management unit 221, and a first node 231. The first management unit 221 and the first node 231 are located in a data center 200, and the operation and maintenance unit 210 is remotely connected to the data center 200. In other words, the first management unit 221 and the first node 231 are located in the same data center, and the operation and maintenance unit 210 and the first management unit 221 are located in different data centers.

[0071] It should be understood that Figure 1 and Figure 2 This is only a schematic architecture diagram of a possible system for determining a network address provided in an embodiment of the present application. The system for determining a network address provided in an embodiment of the present application may also be in other forms.

[0072] For example, the operation and maintenance unit and the first management unit may be located in the same data center, and the first node may be remotely connected to the data center. In other words, the operation and maintenance unit and the first management unit may be located in the same data center, and the first node and the first management unit may be located in different data centers.

[0073] For another example, the operation and maintenance unit and the first node may be located in the same data center, and the first management unit may be remotely connected to the data center. In other words, the operation and maintenance unit and the first node may be located in the same data center, and the first node and the first management unit may be located in different data centers.

[0074] For another example, the operation and maintenance unit, the first management unit and the first node are all connected remotely, or in other words, the operation and maintenance unit, the first management unit and the first node are located in three different data centers.

[0075] In the system for determining a network address provided in an embodiment of the present application, an operation and maintenance unit (e.g., operation and maintenance unit 110 or operation and maintenance unit 210) may be used to determine an IP address of a first node (e.g., first node 131 or first node 231) according to location identification information of a first location where the first node is located. The first node may be managed by a first management unit (e.g., first management unit 121 or first management unit 221). The operation and maintenance unit may also send the IP address of the first node to the first node.

[0076] The embodiments of the present application do not limit the specific form of the IP address. For example, the IP address can be an Internet Protocol version 4 (IPv4) address, an Internet Protocol version 6 (IPv6) address, or a flexible Internet Protocol (Flex IP) address.

[0077] In some embodiments, the operation and maintenance unit may also determine the IP address of the first management unit according to the location identification information of the second location where the first management unit is located. The location identification information of the second location is used to identify the second location, and the IP address of the first management unit is the address for the first management unit to perform network communication.

[0078] In some embodiments, the operation and maintenance unit may send the IP address of the first node or the IP address of the first management unit through a DHCP offer message and / or an acknowledgment message. That is, the IP address of the first node or the IP address of the first management unit may be carried in the DHCP offer message and / or the ack message.

[0079] In some embodiments, the operation and maintenance unit may also determine the location identification information of the second location where the first management unit is located based on the device identification information of the first management unit. The device identification information of the first management unit is used to identify the first management unit. Exemplarily, the operation and maintenance unit may send the location identification information of the second location through a DHCP offer message and / or an acknowledgment (ack) message. That is, the location identification information of the second location may be carried in the DHCP offer message and / or ack message.

[0080] In some embodiments, the device identification information of the first management unit includes the SN of the first management unit and / or the MAC address of the first management unit.

[0081] In some embodiments, the operation and maintenance unit may determine the configuration information based on the location identification information of the first location and / or the IP address of the first node. The operation and maintenance unit may also send the configuration information to the first node, and the configuration information is used to configure the first node. Alternatively, the operation and maintenance unit may also send the location identification information of the first location and / or the IP address of the first node to the configuration unit. The configuration unit may determine the configuration information based on the location identification information of the first location and / or the IP address of the first node. The configuration unit may also send the configuration information to the first node, and the configuration information is used to configure the first node. The configuration unit may be located on the same device or on a different device as the operation and maintenance unit. When the configuration unit and the operation and maintenance unit are located on different devices, the configuration unit may be connected to the operation and maintenance unit. The embodiments of the present application do not limit the specific connection method between the configuration unit and the operation and maintenance unit, for example, it may be a physical direct connection or a remote connection.

[0082] Exemplarily, the configuration information can be used to configure any one or more of the baseboard management controller (BMC), basic input output system (BIOS), time information, operating system, redundant array of independent disks (RAID), network card, etc. of the first node.

[0083] In the system for determining the network address provided in the embodiment of the present application, the first unit may be a first management unit, or the first unit may be managed by the first management unit. When the first unit is managed by the first management unit, the first unit may be, for example, a first node. The first unit may be used to send location identification information of a third location where the first unit is located to the operation and maintenance unit, and the first unit may also receive the IP address of the first unit. The location identification information of the third location is used to identify the third location. The IP address of the first unit is the address of the first unit for network communication.

[0084] For example, when the first unit is a first node, the first node can be used to send location identification information of a first location where the first node is located to the operation and maintenance unit, and the first node can also receive the IP address of the first node. Alternatively, when the first unit is a first management unit, the first management unit can be used to send location identification information of a second location where the first management unit is located to the operation and maintenance unit, and the first management unit can also receive the IP address of the first management unit.

[0085] In some embodiments, the first unit may send the location identification information of the third location via a DHCP discover message, that is, the location identification information of the third location may be carried in the DHCP discover message.

[0086] When the first unit is a first management unit, the first unit may also determine the location identification information of the first location according to the location indication information. The location indication information is used to indicate that the first node is located at the first location and the first node is managed by the first unit. The first unit may also send the location identification information of the first location to the first node, and the location identification information of the first location is used to determine the IP address of the first node.

[0087] Correspondingly, when the first unit is managed by the first management unit, the first unit may send location indication information to the first management unit. The location indication information indicates that the first unit is located at the third location. The first unit may also receive location identification information of the third location from the first management unit.

[0088] When the first unit is the first management unit, the first unit may also send the device identification information of the first unit to the operation and maintenance unit, thereby determining the location identification information of the third location. Alternatively, the first unit may also send the device identification information of the first unit to the operation and maintenance unit, thereby determining the location identification information of the third location and the IP address of the first unit. The device identification information of the first unit is used to identify the first unit. The device identification information of the first unit may include: the SN of the first unit and / or the MAC address of the first unit.

[0089] In some embodiments, the first unit may also receive configuration information and perform configuration according to the configuration information. The configuration information is determined according to the location identification information of the third location and / or the IP address of the first unit. Exemplarily, the configuration information is used to configure one or more of BMC, BIOS, time information, operating system, RAID, network card, etc.

[0090] The operation and maintenance unit can determine the IP address of each node or management unit according to the location of each node or management unit. Since it is relatively easy to obtain the location identification information of each node or management unit, the difficulty of determining the network address of the node or management unit can be reduced. In addition, fewer resources are required to store the location identification information. At the same time, after the node or management unit at each location is replaced, since there is a corresponding relationship between the IP address and the location, the newly replaced node or management unit at the location can directly determine the IP address according to the location without manual configuration or maintenance, thereby reducing the difficulty of determining the IP address of the newly replaced node or management unit and improving the efficiency of determining the IP address of the newly replaced node or management unit.

[0091] Figure 3 It is a schematic flowchart of a method for determining a network address provided in an embodiment of the present application. Figure 3 The method in can be applied to the system for determining the network address provided in the embodiment of the present application, for example Figure 1 or Figure 2 The system in. Figure 3 The method comprises the following steps.

[0092] S310: Determine an IP address of the first node according to location identification information of a first location where the first node is located.

[0093] The operation and maintenance unit may determine the IP address of the first node according to the location identification information of the first location where the first node is located. The first node is managed by the first management unit. In other words, the first location may be located in the area managed by the first management unit. The identification information of the first location is used to identify the first location. The IP address of the first node is the address of the first node for network communication.

[0094] In some embodiments, the data center may include at least one management unit, each of which may manage at least one computing node and / or at least one switching node. The first management unit is any one of the at least one management unit. The first node is any one of the at least one computing node and / or switching node managed by the first management unit.

[0095] For example, suppose a diagram of multiple nodes is as follows Figure 4 shown. Figure 4 It is a schematic diagram of multiple nodes provided in an embodiment of the present application. Figure 4 The management unit 1 includes management unit 1, management unit 2, computing node 1, computing node 2, computing node 3, computing node 4, computing node 5, and switching node 1. Among them, management unit 1 can manage switching node 1, computing node 1, and computing node 2. The area managed by management unit 1 is area 1. That is, the locations of switching node 1, computing node 1, and computing node 2 are all located in area 1. Management unit 2 can manage computing node 3, computing node 4, and computing node 5. The area managed by management unit 2 is area 2. That is, the locations of computing node 3, computing node 4, and computing node 5 are all located in area 2.

[0096] In some embodiments, the operation and maintenance unit and the first management unit may be located in the same device or in different devices.

[0097] For example, suppose a diagram of nodes included in a data center is as follows Figure 4 Step S310 may be performed by management unit 1 or management unit 2. Alternatively, step S310 may be performed by Figure 4The first node may be any one of computing node 1, computing node 2, computing node 3, computing node 4, computing node 5, and switching node 1.

[0098] Optionally, the operation and maintenance unit may determine the IP address of the first node at the first location according to the location identification information of the first location and a first mapping relationship. The first mapping relationship is used to indicate a mapping relationship between the location identification information and the IP address.

[0099] In some embodiments, the operation and maintenance unit may determine the first mapping relationship by itself. Alternatively, the operation and maintenance unit may receive the first mapping relationship from other devices connected to the operation and maintenance unit. The embodiment of the present application does not limit the specific storage form of the first mapping relationship. For example, the first mapping relationship may be stored in a table, array, matrix, function, etc.

[0100] For example, suppose a diagram of nodes included in a data center is as follows Figure 4 As shown, the first mapping relationship may be as shown in Table 1.

[0101] Table 1 First mapping relationship table

[0102] Location identification information IP address 1-1 10.0.1.1 1-2 10.0.1.2 1-3 10.0.1.3

[0103] In Table 1, the position with the position identification information of 1-1 is the first position in area 1, for example, it may be the position where the switching node 1 is located. Similarly, the position with the position identification information of 1-2 is the second position in area 1, for example, it may be the position where the computing node 1 is located. The position with the position identification information of 1-3 is the third position in area 1, for example, it may be the position where the computing node 2 is located. It should be understood that the embodiments of the present application do not limit the ordering method or numbering method of the positions in the area managed by the management unit.

[0104] As shown in Table 1, when the location identification information is 1-1, the operation and maintenance unit can determine that the IP address of the node at the location corresponding to the location identification information is 10.0.1.1 based on the location identification information 1-1 of the location where the computing node 1 is located and the first mapping relationship. That is, the operation and maintenance unit can determine that the IP address of the computing node 1 is 10.0.1.1 based on the location identification information 1-1 of the location where the computing node 1 is located and the first mapping relationship.

[0105] It should be understood that the method of expressing the location identification information in Table 1 is only an example, and the embodiments of the present application do not limit the specific method of expressing the location identification information, and the information that can be used to identify the location can be regarded as the location identification information in the embodiments of the present application. For example, the location identification information can also be expressed in various forms such as 1.1, 1_1, 11, 0101, A-1, A1, a-1, a1, etc. It should also be understood that the embodiments of the present application do not limit the specific method of determining the location identification information. For example, the location identification information of each location can be determined based on the distance between each location in the area managed by the management unit and the management unit. Alternatively, the location identification information of each location in the area managed by the management unit can be determined according to preset rules. The method of determining the location identification information of the locations in the areas managed by different management units may be the same or different, and the embodiments of the present application do not limit this.

[0106] Exemplarily, the location identification information of the location of the node can be used to identify at least one of the computer room area where the node is located, the location coordinates of the node, the cabinet where the node is located, or the slot where the node is located, and the embodiments of the present application do not limit this. In other words, the location of the node can be at least one of the computer room area where the node is located, the coordinates of the node, the cabinet where the node is located, or the slot where the node is located, and the embodiments of the present application do not limit this.

[0107] In some embodiments, the first mapping relationship may only indicate the mapping relationship between the location identification information of the location within the area managed by one management unit and the IP address, as shown in Table 1. Alternatively, the first mapping relationship may indicate the mapping relationship between the location identification information of the location within the area managed by multiple management units and the IP address, as shown in Table 2.

[0108] For example, suppose a diagram of nodes included in a data center is as follows Figure 4 As shown, the first mapping relationship can be as shown in Table 2.

[0109] Table 2 First mapping relationship table

[0110] Location identification information IP address 1-1 10.0.1.1 1-2 10.0.1.2 1-3 10.0.1.3 2-1 10.0.2.1 2-2 10.0.2.2 2-3 10.0.2.3

[0111] In Table 2, the location with location identification information 2-1 is the first location in area 2, for example, it may be the location where computing node 3 is located. Similarly, the location with location identification information 2-2 is the second location in area 2, for example, it may be the location where computing node 4 is located. The location with location identification information 2-3 is the third location in area 2, for example, it may be the location where computing node 5 is located. The first mapping relationship shown in Table 1 may only indicate the mapping relationship between the location identification information of the location in area 1 and the IP address. The first mapping relationship shown in Table 2 may indicate the mapping relationship between the location identification information of the location in area 1 and area 2 and the IP address.

[0112] Optionally, the operation and maintenance unit may directly determine the IP address of the first node according to the location identification information of the first location where the first node is located.

[0113] Exemplarily, the operation and maintenance unit can directly generate the IP address of the first node after obtaining the location identification information of the first location. The operation and maintenance unit can also record the correspondence between the location identification information of the first location and the IP address after generating the IP address of the first node, that is, the operation and maintenance unit can record the first mapping relationship. In other words, the operation and maintenance unit can directly generate the IP address of the node at each location after obtaining the location identification information of each location, and the IP address of each node is different.

[0114] Exemplarily, the operation and maintenance unit may determine the IP address of the first node from an IP address database after obtaining the location identification information of the first location. The IP address database includes at least one unallocated IP address. The operation and maintenance unit may also record the first mapping relationship after determining the IP address of the first node. The operation and maintenance unit may also delete the IP address of the first node from the IP address database after determining the IP address of the first node, or mark the IP address of the first node as allocated.

[0115] Exemplarily, the operation and maintenance unit may determine the IP address database by itself, or receive the IP address database from other devices connected to the operation and maintenance unit, but this embodiment of the present application is not limited to this.

[0116] Optionally, before step S310, the operation and maintenance unit may also receive location identification information of a first location where the first node is located. Correspondingly, the first node may execute step S301.

[0117] S301, sending location identification information of a first location where a first node is located.

[0118] The first node may send location identification information of the current first location to the operation and maintenance unit.

[0119] Optionally, the first node may determine the location identification information of the current first location by itself. Alternatively, the first node may receive the location identification information of the first location from the first management unit.

[0120] In some embodiments, the first node may send location indication information to the first management unit, where the location indication information is used to indicate that the first node is located at the first location. After sending the location indication information to the first management unit, the first node may receive location identification information of the first location.

[0121] Optionally, the first node may send the location identification information of the first location to the operation and maintenance unit through a DHCP discovery message. The discover message may include at least one cell, and each cell may include at least one field. At least one field in the cell may be used to carry the location identification information of the first location. For example, the location identification information of the first location may be carried by a field in the cell. Alternatively, the location identification information of the first location may be carried jointly by multiple fields in the cell, that is, the data in the multiple fields are combined to form the location identification information of the first location. Alternatively, the location identification information of the first location may be repeatedly carried by multiple fields in the cell, that is, each of the multiple fields carries the complete location identification information of the first location, which is not limited in the embodiments of the present application.

[0122] For example, a possible format of a cell in a discover message is Figure 5 shown. Figure 5 It is a schematic diagram of the format of a cell in the discovery message 500 provided in an embodiment of the present application. Figure 5 The information element in the message includes 4 fields, namely, a T field, an L field, an area coordinate field, and a position coordinate field. The T field is a class tag field, and the data in the T field is used to indicate configuration information or identification information, which can be defined according to actual needs. The L field is a length field, and the data in the L field is used to indicate the length of the information element. The area coordinate field is used to indicate the identification information of the area where the first position is located, and the position coordinate field is used to indicate the identification information of the first position in the area. The embodiment of the present application does not limit the length of each field in the information element, and can be set according to actual needs.

[0123] For example, assuming that the location identification information of the first location is 1-2, the data in the area coordinate field in the information element may be 1, and the data in the location coordinate field may be 2.

[0124] It should be understood that the first node may carry the location identification information of the first location through information elements of other formats. Alternatively, the first node may carry the location identification information of the first location through messages of other protocols, which is not limited in the embodiments of the present application.

[0125] S320: Send the IP address of the first node to the first node.

[0126] After determining the IP address of the first node, the operation and maintenance unit may send the IP address to the first node. The IP address of the first node is the address for the first node to perform network communication.

[0127] Optionally, the operation and maintenance unit may send the IP address of the first node to the first node through an ACK message or an offer message of DHCP. The ACK message or the offer message may include at least one cell, and each cell may include at least one field. At least one field in the cell may be used to carry the IP address of the first node. For example, the IP address of the first node may be carried by a field in the cell. Alternatively, the IP address of the first node may be carried jointly by multiple fields in the cell, that is, the data in the multiple fields are combined to form the IP address of the first node. Alternatively, the IP address of the first node may be repeatedly carried by multiple fields in the cell, that is, each of the multiple fields carries the complete IP address of the first node, and the embodiments of the present application are not limited to this.

[0128] It should be understood that the operation and maintenance unit may carry the IP address of the first node through messages of other protocols, and the embodiments of the present application are not limited to this.

[0129] Optionally, after determining the location identification information of the first location and / or the IP address of the first node, the operation and maintenance unit may also determine configuration information. The configuration information is used to configure the first node. For example, the configuration information may be used to configure any one or more of the BMC, BIOS, time information, operating system, RAID, network card, etc. of the first node.

[0130] In some embodiments, the operation and maintenance unit may determine the configuration information according to the location identification information of the first location where the first node is located and the second mapping relationship, wherein the second mapping relationship is used to indicate the mapping relationship between the location identification information and the configuration information.

[0131] In some embodiments, the operation and maintenance unit may determine the second mapping relationship by itself. Alternatively, the operation and maintenance unit may receive the second mapping relationship from other devices connected to the operation and maintenance unit. The embodiment of the present application does not limit the specific storage form of the second mapping relationship. For example, the second mapping relationship may be stored in a table, array, matrix, function, etc.

[0132] For example, suppose a diagram of nodes included in a data center is as follows Figure 4 As shown, Figure 4 If the location identification information of the locations of some nodes in is shown in Table 1, then the second mapping relationship can be shown in Table 3.

[0133] Table 3 Second mapping relationship table

[0134] Location identification information Configuration Information 1-1 Configuration information 1 1-2 Configuration information 2 1-3 Configuration information 3

[0135] In Table 3, configuration information 1, configuration information 2, and configuration information 3 may be the same configuration information. Alternatively, at least two of the configuration information 1, configuration information 2, and configuration information 3 may be different configuration information, which is not limited in the embodiment of the present application.

[0136] As shown in Table 3, when the location identification information is 1-1, the operation and maintenance unit can determine, based on the location identification information and the second mapping relationship, that the configuration information of the node at the location corresponding to the location identification information is configuration information 1. That is, the operation and maintenance unit can determine, based on the location identification information 1-1 of the location where the computing node 1 is located and the second mapping relationship, that the configuration information corresponding to the computing node 1 is configuration information 1.

[0137] In some embodiments, similar to the first mapping relationship, the second mapping relationship may only indicate the mapping relationship between the location identification information and the configuration information of the location within the area managed by one management unit, as shown in Table 3. Alternatively, the second mapping relationship may indicate the mapping relationship between the location identification information and the configuration information of the location within the area managed by multiple management units.

[0138] In some embodiments, the operation and maintenance unit may directly determine the configuration information corresponding to the node at the first position after obtaining the location identification information of the first position. The operation and maintenance unit may also record the mapping relationship between the location identification information of the first position and the configuration information after determining the configuration information of the node at the first position, that is, the operation and maintenance unit may record the second mapping relationship.

[0139] In some embodiments, the operation and maintenance unit may determine the configuration information according to the IP address of the first node and a third mapping relationship, wherein the third mapping relationship is used to indicate a mapping relationship between the IP address and the configuration information.

[0140] In some embodiments, the operation and maintenance unit may determine the third mapping relationship by itself. Alternatively, the operation and maintenance unit may receive the third mapping relationship from other devices connected to the operation and maintenance unit. The embodiment of the present application does not limit the specific storage form of the third mapping relationship. For example, the third mapping relationship may be stored in a table, array, matrix, function, etc.

[0141] For example, suppose a diagram of nodes included in a data center is as follows Figure 4 As shown, Figure 4 The IP addresses of some nodes in are shown in Table 1, and the third mapping relationship can be shown in Table 4.

[0142] Table 4 The third mapping relationship table

[0143] IP address Configuration Information 10.0.1.1 Configuration information 1 10.0.1.2 Configuration information 2 10.0.1.3 Configuration information 3

[0144] As shown in Table 4, when the IP address is 10.0.1.1, the operation and maintenance unit can determine, based on the IP address and the third mapping relationship, that the configuration information corresponding to the IP address is configuration information 1. That is, the operation and maintenance unit can determine, based on the IP address 10.0.1.1 of computing node 1 and the third mapping relationship, that the configuration information corresponding to computing node 1 is configuration information 1.

[0145] In some embodiments, similar to the first mapping relationship, the third mapping relationship may only indicate the mapping relationship between IP addresses and configuration information in an area managed by one management unit, as shown in Table 4. Alternatively, the third mapping relationship may indicate the mapping relationship between IP addresses and configuration information in areas managed by multiple management units.

[0146] In some embodiments, the operation and maintenance unit may directly determine the configuration information corresponding to the node at the first position after obtaining the IP address of the first node. The operation and maintenance unit may also record the mapping relationship between the IP address of the first node and the configuration information after determining the configuration information of the node at the first position, that is, the operation and maintenance unit may record the third mapping relationship.

[0147] In some embodiments, the operation and maintenance unit may determine the configuration information according to the location identification information of the first location, the IP address of the first node, and a fourth mapping relationship, wherein the fourth mapping relationship is used to indicate a mapping relationship between the location identification information, the IP address, and the configuration information.

[0148] In some embodiments, the operation and maintenance unit may determine the fourth mapping relationship by itself. Alternatively, the operation and maintenance unit may receive the fourth mapping relationship from other devices connected to the operation and maintenance unit. The embodiment of the present application does not limit the specific storage form of the fourth mapping relationship. For example, the fourth mapping relationship may be stored in a table, an array, a matrix, a function, etc.

[0149] For example, suppose a diagram of nodes included in a data center is as follows Figure 4 As shown, Figure 4 The location identification information and IP addresses of the locations of some nodes in are shown in Table 1, and the fourth mapping relationship can be shown in Table 5.

[0150] Table 5 Fourth mapping relationship table

[0151] Location identification information IP address Configuration Information 1-1 10.0.1.1 Configuration information 1 1-2 10.0.1.2 Configuration information 2 1-3 10.0.1.3 Configuration information 3

[0152] As shown in Table 5, when the location identification information is 1-1 and the IP address is 10.0.1.1, the operation and maintenance unit can determine, based on the location identification information, the IP address, and the fourth mapping relationship, that the configuration information corresponding to the location identification information and the IP address is configuration information 1. That is, the operation and maintenance unit can determine, based on the location identification information 1-1 of the location where the computing node 1 is located, the IP address 10.0.1.1 of the computing node 1, and the fourth mapping relationship, that the configuration information corresponding to the computing node 1 is configuration information 1.

[0153] In some embodiments, similar to the first mapping relationship, the fourth mapping relationship may only indicate the mapping relationship between the location identification information, the IP address, and the configuration information in the area managed by one management unit, as shown in Table 5. Alternatively, the fourth mapping relationship may indicate the mapping relationship between the location identification information, the IP address, and the configuration information in the areas managed by multiple management units.

[0154] In some embodiments, the operation and maintenance unit may directly determine the configuration information of the node at the first location after obtaining the location identification information of the first location and / or the IP address of the first node. The operation and maintenance unit may also record the mapping relationship between the location identification information of the first location, the IP address of the first node, and the configuration information after determining the configuration information of the node at the first location, that is, the operation and maintenance unit may record the fourth mapping relationship.

[0155] Optionally, after determining the location identification information of the first location and / or the IP address of the first node, the operation and maintenance unit may also send the location identification information of the first location and / or the IP address of the first node to the configuration unit. The configuration unit may be located on the same device or on different devices as the operation and maintenance unit. When the configuration unit and the operation and maintenance unit are located on different devices, the configuration unit may be connected to the operation and maintenance unit. The embodiment of the present application does not limit the location of the configuration unit, for example, the configuration unit may be located within or outside the area managed by the first management unit. After obtaining the location identification information of the first location and / or the IP address of the first node, the configuration unit may determine the configuration information according to the location identification information of the first location and / or the IP address of the first node. The configuration information is used to configure the first node. For example, the configuration information may be used to configure any one or more of the BMC, BIOS, time information, operating system, RAID, network card, etc. of the first node. The configuration unit determines the configuration information in a manner similar to the operation and maintenance unit, which will not be repeated here.

[0156] Optionally, after the operation and maintenance unit determines the configuration information, the configuration information may be sent to the first node. Alternatively, after the configuration unit determines the configuration information, the configuration information may be sent to the first node. Correspondingly, the first node may receive the configuration information and configure according to the configuration information. The configuration information is determined according to the location identification information of the first location and / or the IP address of the first node.

[0157] The operation and maintenance unit can determine the IP address of each node according to the location of each node without querying the SN and / or MAC address of each node, thereby reducing the difficulty of determining the network address of the node. In addition, the resources required to store the location identification information are less than the resources to store the SN / MAC address, so storage resources can be saved. At the same time, after the node at each location is replaced, since there is a corresponding relationship between the IP address and the location, the newly replaced node at the location can directly determine the IP address according to the location without manual configuration or maintenance, thereby reducing the difficulty of determining the IP address of the newly replaced node and improving the efficiency of determining the IP address of the newly replaced node. The operation and maintenance unit or the configuration unit can also determine the configuration information of the node at the first location according to the location identification information of the first location or the IP address corresponding to the first location, thereby configuring the node at the first location. Even if the node or device at the first location is replaced, the configuration of the node or device at the location can still be kept consistent, thereby maintaining the consistency of the business.

[0158] Figure 6 It is a schematic flowchart of a method for determining a network address provided in an embodiment of the present application. Figure 6 The method in can be applied to the system for determining the network address provided in the embodiment of the present application, for example Figure 1 or Figure 2 in the system. Figure 6 The method comprises the following steps.

[0159] S610: Send location identification information of a second location where a first management unit is located.

[0160] When the first management unit and the operation and maintenance unit are located in different devices, the first management unit may send the location identification information of the second location where the first management unit is located to the operation and maintenance unit. The location identification information of the second location is used to identify the second location. Correspondingly, the operation and maintenance unit may receive the location identification information of the second location from the first management unit.

[0161] When the first management unit and the operation and maintenance unit are located in the same device, the operation and maintenance unit (or the first management unit) may directly determine the location identification information of the second location, that is, step S610 may not be executed.

[0162] Optionally, the first management unit may determine the location identification information of the second location by itself. Alternatively, the first management unit may receive the location identification information of the second location from other nodes or devices connected to the first management unit.

[0163] In some embodiments, the first management unit may send the device identification information of the first management unit to the operation and maintenance unit, thereby determining the location identification information of the second location. The device identification information of the first management unit is used to identify the first management unit. For example, the device identification information of the first management unit may include the SN and / or MAC address of the first management unit. Alternatively, the device identification information of the first management unit may be customized data.

[0164] S620: Determine the IP address of the first management unit according to the location identification information of the second location.

[0165] After determining the location identification information of the second location, the operation and maintenance unit can determine the IP address of the first management unit according to the location identification information of the second location. The IP address of the first management unit is the address for the first management unit to perform network communication.

[0166] Optionally, the operation and maintenance unit may directly determine the IP address of the first management unit after determining the location identification information of the second location. Alternatively, the operation and maintenance unit may determine the IP address of the first management unit based on the location identification information of the second location and the fifth mapping relationship. The fifth mapping relationship is used to indicate the correspondence between the location identification information of the second location and the IP address of the first management unit. The fifth mapping relationship may be similar to the first mapping relationship. The manner in which the operation and maintenance unit determines the corresponding IP address based on the location identification information of the second location is similar to the manner described in step S310 and will not be repeated here.

[0167] Optionally, the operation and maintenance unit may receive device identification information from the first management unit before step S620. The operation and maintenance unit may also determine the location identification information of the second location where the first management unit is located and / or the IP address of the first management unit according to the device identification information of the first management unit.

[0168] In some embodiments, the operation and maintenance unit may determine the location identification information of the second location according to the device identification information of the first management unit and a sixth mapping relationship, wherein the sixth mapping relationship is used to indicate a mapping relationship between the location identification information and the device identification information.

[0169] In some embodiments, the operation and maintenance unit may determine the sixth mapping relationship by itself. Alternatively, the operation and maintenance unit may receive the sixth mapping relationship from other devices connected to the operation and maintenance unit. The embodiment of the present application does not limit the specific storage form of the sixth mapping relationship. For example, the sixth mapping relationship may be stored in a table, an array, a matrix, a function, etc.

[0170] For example, suppose a diagram of nodes included in a data center is as follows Figure 4 As shown, the sixth mapping relationship can be as shown in Table 6.

[0171] Table 6 Sixth mapping relationship table

[0172] Device identification information Location identification information SN1 1-0 SN2 2-0

[0173] In Table 6, SN1 is the device identification information of management unit 1, and SN2 is the device identification information of management unit 2. As shown in Table 6, when the device identification information is SN1, the operation and maintenance unit can determine that the location identification information at the location corresponding to the device identification information is 1-0 based on the device identification information and the sixth mapping relationship. That is, the operation and maintenance unit can determine that the location identification information of the location where the management unit 1 is located is 1-0 based on the device identification information SN1 of the management unit 1 and the sixth mapping relationship.

[0174] In some embodiments, the operation and maintenance unit may directly determine the location identification information of the second location based on the device identification information of the first management unit.

[0175] Exemplarily, the operation and maintenance unit can directly generate the location identification information of the second location after obtaining the device identification information of the first management unit. The operation and maintenance unit can also record the correspondence between the location identification information of the second location and the device identification information of the first management unit after generating the location identification information of the second location, that is, the operation and maintenance unit can record the sixth mapping relationship. In other words, the operation and maintenance unit can directly generate the location identification information of the location where each management unit is located after obtaining the device identification information of each management unit, and the location identification information of each location is different.

[0176] Exemplarily, the operation and maintenance unit may determine the location identification information of the second location from the regional identification database after obtaining the device identification information of the first management unit. The regional identification database includes at least one unallocated location identification information. The operation and maintenance unit may also record the sixth mapping relationship after determining the location identification information of the second location. The operation and maintenance unit may also delete the location identification information of the second location from the regional identification database after determining the location identification information of the second location, or mark the location identification information of the second location as allocated.

[0177] Exemplarily, the operation and maintenance unit may determine the region identification database by itself, or receive the region identification database from other devices connected to the operation and maintenance unit, which is not limited in this embodiment of the present application.

[0178] Optionally, the operation and maintenance unit may send the location identification information of the second location where the first management unit is located to the first management unit through an ack message or an offer message of DHCP. The ack message or the offer message may include at least one information element, and each information element may include at least one field. At least one field in the information element may be used to carry the location identification information of the second location. For example, the location identification information of the second location may be carried through a field in the information element. Alternatively, the location identification information of the second location may be carried jointly through multiple fields in the information element, that is, the data in the multiple fields are combined to form the location identification information of the second location. Alternatively, the location identification information of the second location may be repeatedly carried through multiple fields in the information element, that is, each of the multiple fields carries the complete location identification information of the second location, which is not limited in the embodiments of the present application.

[0179] For example, a possible format of a cell in an offer message is Figure 7 shown. Figure 7 It is a schematic diagram of the format of a cell in the message 700 provided in an embodiment of the present application. Figure 7 The information element in the message includes three fields, namely, a T field, an L field, and an area coordinate field. The T field is a class tag field, and the data in the T field is used to indicate configuration information or identification information, which can be defined according to actual needs. The L field is a length field, and the data in the L field is used to indicate the length of the information element. The area coordinate field is used to indicate the identification information of the area where the second position is located. The embodiment of the present application does not limit the length of each field in the information element, and can be set according to actual needs. In some examples, the information element may also include a location coordinate field, which is used to indicate the identification information of the second position in the area.

[0180] For example, assuming that the location identification information of the second location is 1-0, the data of the area coordinate field in the information element may be 1. When the location coordinate field is included in the information element, the data of the location coordinate field may be 0.

[0181] It should be understood that the way in which the ack message carries the location identification information of the second location is similar to that of the offer message, and will not be repeated here. It should also be understood that the operation and maintenance unit can carry the location identification information of the second location through other formats of information elements. Alternatively, the operation and maintenance unit can carry the location identification information of the second location through messages of other protocols, which is not limited in the embodiments of the present application.

[0182] In some embodiments, the operation and maintenance unit may determine the IP address of the first management unit according to the device identification information of the first management unit and a seventh mapping relationship. The seventh mapping relationship is used to indicate a mapping relationship between the device identification information and the IP address.

[0183] In some embodiments, the operation and maintenance unit may determine the seventh mapping relationship by itself. Alternatively, the operation and maintenance unit may receive the seventh mapping relationship from other devices connected to the operation and maintenance unit. The embodiment of the present application does not limit the specific storage form of the seventh mapping relationship. For example, the seventh mapping relationship may be stored in a table, an array, a matrix, a function, etc.

[0184] For example, suppose a diagram of nodes included in a data center is as follows Figure 4 As shown, the seventh mapping relationship can be as shown in Table 7.

[0185] Table 7 Seventh mapping relationship table

[0186] Device identification information IP address SN1 10.0.1.0 SN2 10.0.2.0

[0187] As shown in Table 7, when the device identification information is SN1, the operation and maintenance unit can determine that the IP address of the node or device corresponding to the device identification information is 10.0.1.0 based on the device identification information SN1 of the management unit 1 and the seventh mapping relationship. That is, the operation and maintenance unit can determine that the IP address of the management unit 1 is 10.0.1.0 based on the device identification information SN1 of the management unit 1 and the seventh mapping relationship.

[0188] In some embodiments, the operation and maintenance unit may directly determine the IP address of the first management unit based on the device identification information of the first management unit.

[0189] Exemplarily, the operation and maintenance unit can directly generate the IP address of the first management unit after obtaining the device identification information of the first management unit. The operation and maintenance unit can also record the correspondence between the IP address of the first management unit and the device identification information of the first management unit after generating the IP address of the first management unit, that is, the operation and maintenance unit can record the seventh mapping relationship. In other words, the operation and maintenance unit can directly generate the IP address of each management unit after obtaining the device identification information of each management unit, and the IP address of each management unit is different.

[0190] Exemplarily, the operation and maintenance unit may determine the IP address of the first management unit from an IP address database after obtaining the device identification information of the first management unit.

The operation and maintenance unit may also delete the IP address of the first management unit from the IP address database after determining the IP address of the first management unit, or mark the IP address of the first management unit as allocated.

[0191] Exemplarily, the operation and maintenance unit may determine the IP address database by itself, or receive the IP address database from other devices connected to the operation and maintenance unit, but this embodiment of the present application is not limited to this.

[0192] In some embodiments, the operation and maintenance unit may determine the location identification information of the second location and the IP address of the first management unit according to the device identification information of the first management unit and an eighth mapping relationship. The eighth mapping relationship is used to indicate the mapping relationship between the device identification information, the location identification information and the IP address.

[0193] In some embodiments, the operation and maintenance unit may determine the eighth mapping relationship by itself. Alternatively, the operation and maintenance unit may receive the eighth mapping relationship from other devices connected to the operation and maintenance unit. The embodiment of the present application does not limit the specific storage form of the eighth mapping relationship. For example, the eighth mapping relationship may be stored in a table, an array, a matrix, a function, etc.

[0194] For example, suppose a diagram of nodes included in a data center is as follows Figure 4 As shown, the eighth mapping relationship can be as shown in Table 8.

[0195] Table 8 Eighth mapping relationship table

[0196] Device identification information Location identification information IP address SN1 1-0 10.0.1.0 SN2 2-0 10.0.2.0

The operation and maintenance unit can also record the correspondence between the location identification information of the second location, the IP address of the first management unit and the device identification information of the first management unit after generating the location identification information of the second location and the IP address of the first management unit, that is, the operation and maintenance unit can record the eighth mapping relationship. In other words, after obtaining the device identification information of each management unit, the operation and maintenance unit can directly generate the location identification information of the location where each management unit is located and the IP address of each management unit, and the location identification information of each location is different, and the IP address of each management unit is different.

[0200] Exemplarily, after obtaining the device identification information of the first management unit, the operation and maintenance unit may determine the location identification information of the second location from the regional identification database, and determine the IP address of the first management unit from the IP address database. The regional identification database includes at least one unallocated location identification information. The IP address database includes at least one unallocated IP address.
