Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of switching device, in particular to a method for processing information, related device and network system. BACKGROUND

[0002] In a network architecture such as a storage area network (SAN), computing nodes and storage nodes (collectively referred to as nodes) are usually connected through a switching network comprising multiple switching devices, thereby constructing a storage system. In actual use, each switching device usually needs to synchronize information about computing nodes and storage nodes, so that a node can timely perceive the state of an associated node, thereby determining the operation between nodes, for example, a computing node can perceive that a storage node is online or offline, thereby establishing a connection or disconnecting with the storage node.

[0003] However, with the continuous growth of business scale, the scale of nodes in the storage system is increasing, and the information about computing nodes and storage nodes that the switching devices in the storage system need to store also increases significantly, resulting in that the switching devices need to consume a large amount of resources to store information about computing nodes and storage nodes, for example, a large number of related entries need to be stored, and the storage resources of the switching devices are consumed greatly. SUMMARY

[0004] The present application provides a network system to solve the problem that the switching devices in the current storage system need to consume a large amount of storage resources to store information about computing nodes and storage nodes, resulting in a large consumption of storage resources. The present application also provides corresponding methods, devices, switching devices, computer-readable storage media and computer program products, etc.

[0005] The first aspect of the present application provides a network system, the network system comprising a first switching device and a second switching device, the network system corresponding to at least one partition set, each partition set comprising at least one partition, each partition comprising a plurality of nodes allowed to visit each other, the partitions contained in different partition sets being different, and the partitions in different partition sets being isolated from each other; the first switching device is configured to send a first message to the second switching device, the first message comprising information of a first node, the first node being a node in a first partition set corresponding to the first switching device; the second switching device is configured to receive the first message, and when the first node is related to a second partition set corresponding to the second switching device, update the information of the first node in the second switching device according to the first message.

[0006] In the first aspect, each partition set includes one or more partitions. The isolation of partitions within different partition sets means that each partition in a different partition set is managed independently. The first message can be sent as a separate data packet from the first switching device to the second switching device, or it can be merged with information from nodes other than the first node into a single data packet, which is then sent from the first switching device to the second switching device. In this case, the second switching device can retrieve the first message from the merged data packet using a specific information identifier. There are several ways to update the information of the first node in the second switching device based on the first message. In one example, if the second switching device already stores historical version information of the first node, then when the first node is associated with the second partition set corresponding to the second switching device, the second switching device can replace the historical version information of the first node in the second switching device with the received information of the first node. In another example, if the second switching device does not store the information of the first node, then when the first node is associated with the second partition set corresponding to the second switching device, the second switching device stores the information of the first node for the first time to update the information of the first node in the second switching device for the first time.

[0007] As described above, in this first aspect, the various partitions corresponding to the network system can be combined to obtain a partition set, wherein the partitions in different partition sets are isolated from each other. Furthermore, the first switching device sends a first message including information about the first node to the second switching device. The second switching device receives the first message and, when the first node is associated with a second partition set corresponding to the second switching device, updates the information of the first node in the second switching device according to the first message. In this way, the second switching device does not need to store information about all nodes globally, thus reducing the consumption of storage resources.

[0008] In one possible implementation of the first aspect, the second switching device is further configured to: not process the first message when the first node is not related to the second partition set.

[0009] In this possible implementation, not processing the first message means not performing any corresponding operations based on the content of the first message, such as performing an update operation on the corresponding information. In this way, when the first node and the second partition set are not related, the second switching device determines that the first message is not related to the second switching device, thus eliminating the need for storage and reducing the waste of storage resources in the second switching device.

[0010] In a possible implementation of the first aspect, the second exchange device stores the receiving identifiers of the second partition set, and the information of the first node includes a sending identifier of a third partition set corresponding to the first node, the third partition set belonging to the first partition set; the first node is associated with the second partition set corresponding to the second exchange device, including that the receiving identifier of the second partition set matches the sending identifier of the third partition set.

[0011] In an example, one partition set can be uniquely identified by using one identifier parameter, which serves as both the receiving identifier and the sending identifier. In another example, one partition set can use two identifier parameters to represent the sending identifier and the receiving identifier respectively, and the two identifier parameters corresponding to one partition set have the same value, in which case the receiving identifier and the sending identifier corresponding to one partition set are the same; or the two identifier parameters corresponding to one partition set have different values, in which case the receiving identifier and the sending identifier corresponding to one partition set are different, so that the transmission direction of the relevant message between the exchange devices can be embodied by the receiving identifier and the sending identifier with different values.

[0012] In a possible implementation of the first aspect, the second partition set includes a plurality of partition sets, and the receiving identifier of the second partition set matches the sending identifier of the third partition set includes that the receiving identifier of at least one partition set in the plurality of partition sets matches the sending identifier of the third partition set.

[0013] In this possible implementation, some partition sets in the second partition set can be associated with the third partition set, or all partition sets in the second partition set can be associated with the third partition set, which is not limited.

[0014] In a possible implementation of the first aspect, the second exchange device is further configured to: receive a configuration message sent by the first exchange device, the configuration message including the sending identifier of the first partition set and first configuration information of the first partition set; and when the sending identifier of the first partition set matches the receiving identifier of the second partition set, update second configuration information of the second partition set according to the configuration message, the second configuration information including the identifier of the partition corresponding to the second partition set and the information of the node included in the corresponding partition.

[0015] In the possible implementation manner, the second configuration information usually has a large data amount and can be dynamically adjusted by the user according to the situation. If the configuration and deployment are performed for each switching device one by one, the labor cost and time cost are high. Therefore, in the possible implementation manner, the first switching device can acquire the configuration information, the first switching device can send the configuration information to the second switching device, and the second switching device can identify the related information based on the stored receiving identifier to update the second configuration information, so that the updating efficiency of the configuration information can be improved. In a scenario, when the first switching device is a reflector, the configuration information can be sent to the plurality of reflector clients connected to the first switching device, so that the efficient updating of the corresponding configuration information of the plurality of reflector clients can be implemented.

[0016] In a possible implementation manner of the first aspect, the second switching device further includes: an acquiring unit, configured to acquire state change information of a second node associated with the second switching device; and a sending unit, configured to send a second message to the first switching device, the second message including the state change information of the second node and a sending identifier of a fourth partition set corresponding to the second node, the fourth partition set belonging to the second partition set.

[0017] In the possible implementation manner, the corresponding information interaction can be performed based on the state change information of the node, so that the data synchronization of the related state change information in the related switching device can be implemented.

[0018] In a possible implementation manner of the first aspect, the first switching device further includes: a receiving unit, configured to receive the second message; and an updating unit, configured to, when the sending identifier of the fourth partition set matches the receiving identifier of the first partition set, update the information of the second node in the first switching device according to the state change information of the second node and the sending identifier of the fourth partition set.

[0019] In the possible implementation manner, the first switching device can determine whether the fourth partition set corresponding to the second node is the partition set associated with the first switching device through the sending identifier in the second message, and then determine whether the information updating in the first switching device needs to be performed based on the second message, so that the data amount of the irrelevant data stored in the first switching device can be reduced, and the waste of storage resources can be reduced.

[0020] In a possible implementation manner of the first aspect, the first switching device further includes: a generating unit, configured to generate a third message, the third message including the state change information of the second node and the sending identifier of the fourth partition set; and a sending unit, configured to send the third message to other switching devices connected to the first switching device and other than the second switching device.

[0021] In the possible implementation manner, when the partition set of the other switching device connected to the first switching device is related to the second node, the other switching device can perform the related updating operation according to the third information, so that the updating of the related data can be implemented.

[0023] In the possible implementation, the network system includes the first switching device as the first reflector and the third switching device as the second reflector, and the first reflector and the second reflector correspond to different partition sets. In this way, the related node information and the related configuration information of different partition sets can be respectively stored in different reflectors, thereby avoiding the problem of excessive load caused by the fact that a single reflector in the network system needs to store and process a large amount of information of partition sets, and load sharing in the network system is achieved.

[0025] In the possible implementation, the first subsystem and the second subsystem are located in different data centers. In addition, the reflectors of different subsystems are different, so that different subsystems bear the collection and transmission of the related configuration information and the related node information between the switching devices through different reflectors, thereby reasonably allocating device resources and achieving load sharing of the switching devices between the plurality of subsystems.

[0026] In a possible implementation of the first aspect, in a partition set, the corresponding nodes are in a relationship of intercommunication in a same data center, or the corresponding nodes are in a relationship of intercommunication across data centers.

[0029] In a possible implementation manner of the second aspect, the first switching device further generates a third message, the third message comprising the state change information of the second node and the sending identifier of the fourth partition set; and the third message is sent to other switching devices connected to the first switching device except the second switching device.

When the sending identifier of the first partition set matches the receiving identifier of the second partition set, the second configuration information of the second partition set is updated according to the configuration message. The second configuration information includes the identifier of the partition corresponding to the second partition set and the information of the nodes included in the corresponding partition.

[0066] The embodiments of the present application are described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Those skilled in the art can know that with the development of technology and the emergence of new scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0067] In the present application, "at least one" means one or more, and "multiple" means two or more. The "and / or" describes the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the front and rear associated objects. "At least one of the following" or similar expressions means any combination of these items, including any combination of single or multiple items. The terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0068] The embodiments of the present application provide a network system to solve the problem that the switching device in the current storage system needs to consume a large amount of storage resources to store configuration information about the computing nodes and the storage nodes, resulting in a large consumption of storage resources. The embodiments of the present application also provide corresponding methods, switching devices, computer readable storage media, and computer program products, etc.

[0069] The network system includes a plurality of switching devices, and one or more switching devices in the network system can be connected with nodes.

[0070] The number of nodes associated with the network system is not limited here, and the number of nodes associated with the network system can change over time. Functionally, any node in the embodiments of this application can be a computing node or a storage node. The computing node can access the storage node and retrieve data from the storage node through the network system. The storage node can store data; it can be a single storage unit or a storage array comprising multiple storage units. In terms of form, the nodes in the embodiments of this application can be physical devices or virtual devices deployed on physical devices. For example, a computing node can be a physical server, workstation, mobile station, or other type of computer equipment, or a virtual device in the form of a virtual machine (VM) or container. When a node is a virtual device, multiple nodes can be hosted on the same physical device.

[0071] The network system and nodes can be part of the storage system. For example, the storage system can be an Ethernet storage system, and the switching devices in the network system of the storage system are Ethernet switching devices.

[0072] This storage system can contain one or more data centers, each capable of performing corresponding data storage operations. If the storage system has multiple data centers, these multiple data centers can form a dual-active data center, three or more multi-active data centers, a primary-backup data center, etc. Taking a dual-active data center as an example, in a dual-active data center, both data centers are in an active state, and the storage nodes of these two data centers serve as backups for each other.

[0073] The network topology formed by the switching devices in each data center is not limited here. In one example, the switching devices in the data center may include access switching devices (also called edge switching devices or leaf switching devices) and aggregation switching devices connected to the nodes, with the aggregation switching devices used to connect the access switching devices. Alternatively, in another example, the data center may include access switching devices, aggregation switching devices, and core switching devices, with the aggregation switching devices used to connect the core switching devices and access switching devices. The switching devices in each data center can realize data transmission between the compute nodes and storage nodes corresponding to that data center.

[0074] like Figure 1 The diagram shown is an exemplary structural diagram of a storage system, which includes data center 10 and data center 11. Each data center includes compute nodes and storage nodes, and the compute nodes and storage nodes communicate with each other through a switching device.

[0075] The storage system is constructed based on a storage area network (SAN). The data center 10 and the data center 11 form a dual-active data center, and the storage nodes of the data center 10 and the data center 11 are backed up to each other.

[0076] At least two switching devices in the storage system can belong to the network system provided in the embodiments of the present application. The network system provided in the embodiments of the present application is specifically introduced below. Figure 2 The network system provided in the embodiments of the present application is specifically introduced below.

[0077] As shown in FIG. 1, it is a schematic diagram of an exemplary structure of the network system. Figure 2

[0078] The network system 2 can include a first switching device 201 and a second switching device 202.

[0079] The first switching device 201 and the second switching device 202 included in the network system in the embodiments of the present application can be located in the same data center or different data centers. The embodiments of the present application do not limit this.

[0080] In the embodiments of the present application, the network system corresponds to at least one zone set, each zone set includes at least one zone, each zone includes a plurality of nodes allowed to visit each other, the zones included in different zone sets are different, and the zones in different zone sets are isolated from each other.

[0081] In the embodiments of the present application, these nodes can be grouped by zoning technology, which is called a zone. Each zone can include a plurality of nodes. Generally, the computing nodes and the storage nodes in the same zone can access each other (referred to as visiting each other in the embodiments of the present application) through the network system, thereby communicating. A node can belong to multiple zones, and the node can communicate with other nodes belonging to the same zone. The specific setting method of the zone can be various, which is not limited in the embodiments of the present application.

[0082] In the embodiments of the present application, each zone set includes at least one zone, the zones included in different zone sets are different, and the zones in different zone sets are isolated from each other.

[0083] The isolation of the zones in different zone sets can mean that the zones in different zone sets are independently managed. When the switching device receives the information of the relevant zone set, the switching device manages the information of the zone set, and when the switching device receives the information of the irrelevant zone set, the switching device does not manage the information of the zone set, thereby realizing the independent management of each zone set in the switching device.

[0084] For example, as shown in FIG. 2, it is a schematic diagram of another exemplary structure of the network system. Figure 3a ​An exemplary schematic diagram of the switching devices and related nodes is shown.

[0085] wherein, Figure 3a The switching devices and nodes shown can form data center 30 and data center 31. Data center 30 and data center 31 form a dual-active data center. Any computing node in data center 30 (such as computing node 301, computing node 302, or computing node 303) can access a storage node in data center 30 (such as storage node 321 or storage node 322), and can also access a storage node in data center 31 (such as storage node 323 or storage node 324) across data centers.

[0086] Figure 3a The nodes shown form at least the following partitions:

[0087] Partition a1: computing node 301, storage node 321, storage node 322;

[0088] Partition a2: computing node 302, storage node 321, storage node 322;

[0089] Partition a3: computing node 303, storage node 321, storage node 322;

[0090] Partition a4: computing node 301, storage node 323, storage node 324;

[0091] Partition a5: computing node 302, storage node 323, storage node 324;

[0092] Partition a6: computing node 303, storage node 323, storage node 324.

[0093] wherein, partition a1, partition a2, and partition a3 are relationships of the corresponding nodes accessing each other in the same data center, and partition a4, partition a5, and partition a6 are relationships of the corresponding nodes accessing each other across data centers. Based on the categories of the above-mentioned access relationships, partition set A1 and partition set A2 can be obtained, wherein:

[0094] Partition set A1: partition a1, partition a2, and partition a3;

[0095] Partition set A2: partition a4, partition a5, and partition a6.

[0096] It can be seen that in some embodiments, in one partition set, the corresponding nodes are all in the relationship of accessing each other in the same data center, or the corresponding nodes are all in the relationship of accessing each other across data centers.

[0097] In Figure 3aIn the illustrated example, the switching device 313 can only store information related to the partition set A1, and not information related to the partition set A2.

[0098] Figure 3a Other partition sets can also be included, which are not listed here.

[0099] As Figure 3b Another exemplary schematic diagram of switching devices and related nodes is shown.

[0100] Figure 3b The association between each node and the switching device is shown in Figure 3b In

[0101] Based on the association between each node and the switching device in Figure 3b Figure 3b The nodes shown form at least the following partitions:

[0102] Partition b1: computing node 331, storage node 341, storage node 342;

[0103] Partition b2: computing node 332, storage node 341, storage node 342;

[0104] Partition b3: computing node 333, storage node 341, storage node 342;

[0105] Partition b4: computing node 334, storage node 343, storage node 344;

[0106] Partition b5: computing node 335, storage node 343, storage node 344;

[0107] Partition b6: computing node 336, storage node 343, storage node 344.

[0108] Combining the above partitions b1-b6, the partition set B1 and the partition set B2 can be obtained, where:

[0109] Partition set B1: partition b1, partition b2, and partition b3;

[0110] Partition set B2: partition b4, partition b5, and partition b6.

[0111] The switching device 351 and the switching device 353 can only store information related to the partition set B1, and not information related to the partition set B2, and the switching device 354 and the switching device 355 can only store information related to the partition set B2, and not information related to the partition set B1, thereby saving storage resources in these switching devices. ​

[0112] Based on the network system in any of the above embodiments, an embodiment of the present application provides a method for processing information. As shown in the figure, the method comprises steps 401-402. Figure 4

[0113] Step 401, the first switching device sends a first message to the second switching device.

[0114] Exemplarily, in the example shown in the figure, the first switching device can be switching device 312 or switching device 315, and the second switching device can be switching device 311, switching device 313, switching device 314 or switching device 316. While in the example shown in the figure, the first switching device can be switching device 352, and the second switching device can be switching device 351, switching device 353, switching device 354 or switching device 355. Figure 3a Figure 3b

[0115] The first message comprises information of a first node, which is a node in a first partition set corresponding to the first switching device.

[0116] In the embodiment of the present application, the number of the first nodes is not limited herein. The first node can be part of or all of the nodes in the first partition set corresponding to the first switching device. The information of the first node can comprise information of the first node itself, and can also comprise association information of the corresponding node and other related devices. Exemplarily, the information of the first node can comprise at least one of the following information:

[0117] Internet Protocol (IP) address of the first node, IP state of the first node, connection state between the first node and the corresponding access switching device, IP address of the access switching device corresponding to the first node, interface information of the access switching device corresponding to the first node, and access state between the first node and the corresponding first switching device.

[0118] The information of the first node can be received by the first switching device from other switching devices connected to the first switching device except the second switching device, or can also be information configured by a user on the first switching device, or can also be received by the first switching device from other devices such as user terminals.

[0119] In an example, other switching devices (such as other access switching devices) connected to the first switching device except the second switching device can generate the information of the first node and send it to the first switching device when detecting that the state of the first node changes (for example, the first node newly accesses the corresponding switching device and establishes a connection or changes from a connected state to a disconnected state). ​​​

[0120] In another example, the user can configure the information of the first node in the first switching device.

[0121] In the embodiments of the present application, the first message can be sent by the first switching device to the second switching device as an independent data packet, or can be merged into a same data packet with the information of other nodes except the first node, and then the first switching device sends the data packet obtained after the merging to the second switching device. At this time, the second switching device can acquire the first message from the data packet obtained after the merging through a specific information identifier.

[0122] In step 402, the second switching device receives the first message, and when the first node is related to the second partition set corresponding to the second switching device, the second switching device updates the information of the first node in the second switching device according to the first message.

[0123] In the embodiments of the present application, whether the first message is related to the second partition set corresponding to the second switching device can be determined based on the specified identifier (for example, the sending identifier corresponding to the first message) in the first message and the specified identifier (for example, the receiving identifier in the second switching device) in the second switching device. The specified identifier can be set in multiple ways. In one example, one partition set can be uniquely identified by one identifier parameter, which is used as both the receiving identifier and the sending identifier. In another example, one partition set can use two identifier parameters to represent the sending identifier and the receiving identifier respectively, and the values of the two identifier parameters corresponding to one partition set can be the same, in which case the receiving identifier and the sending identifier corresponding to one partition set are the same; or the values of the two identifier parameters corresponding to one partition set can be different, in which case the receiving identifier and the sending identifier corresponding to one partition set are different. At this time, if the sending identifier in the first message matches the receiving identifier in the second switching device, it is determined that the first message is related to the second partition set corresponding to the second switching device.

[0124] The way of updating the information of the first node in the second switching device according to the first message can be various.

[0125] In one example, the second switching device has already stored the historical version information of the first node, and when the first node is related to the second partition set corresponding to the second switching device, the second switching device can replace the historical version information of the first node in the second switching device with the received information of the first node.

[0126] In another example, the second switching device does not store information of the first node, and the second switching device can first store the information of the first node to first update the information of the first node in the second switching device when the first node is related to the second partition set corresponding to the second switching device. In this case, the second switching device can only store the identifier of the first node (e.g., the name of the first node), but not store information such as the IP address of the first node, the connection state with the corresponding switching device, and the like, or can not store any information of the first node.

[0127] In the embodiments of the present application, each partition corresponding to the network system can be combined to obtain a partition set, wherein the partitions in different partition sets are isolated from each other, and the first switching device can send a first message including the information of the first node to the second switching device, and the second switching device can receive the first message and update the information of the first node in the second switching device according to the first message when the first node is related to the second partition set corresponding to the second switching device. In this way, the second switching device does not need to store information of all nodes globally, and thus the consumption of storage resources can be reduced.

[0128] In some embodiments, when the first node is not related to the second partition set, the second switching device does not process the first message.

[0129] In this case, the second switching device does not need to store the first message when the first node is not related to the second partition set, and thus the waste of storage resources in the second switching device can be reduced.

[0130] In some embodiments, the second switching device stores a receiving identifier of the second partition set, the information of the first node includes a sending identifier of a third partition set corresponding to the first node, the third partition set belongs to the first partition set, and the first node is related to the second partition set corresponding to the second switching device includes that:

[0131] The receiving identifier of the second partition set matches the sending identifier of the third partition set.

[0132] In the embodiments of the present application, for any partition set, the partition set corresponds to a receiving identifier and a sending identifier. The sending identifier is used to mark the sending identifier when the switching device sends information related to the partition set. The receiving identifier is used to match the received message based on the receiving identifier when the switching device receives the message to determine whether the received message is related to the partition set corresponding to the switching device.

[0133] In an example, one partition set can use one identification parameter to be uniquely identified, which is used as both the receiving identification and the sending identification. In another example, one partition set can use two identification parameters to represent the sending identification and the receiving identification respectively, and the two identification parameters corresponding to one partition set have the same value, in which case, the receiving identification and the sending identification corresponding to one partition set are the same; or the two identification parameters corresponding to one partition set have different values, in which case, the receiving identification and the sending identification corresponding to one partition set are different, so that the transmission direction of the related message between the switching devices can be embodied by the receiving identification and the sending identification with different values.

[0134] In some embodiments, the second partition set includes a plurality of partition sets, and the receiving identification of the second partition set matches the sending identification of the third partition set includes that:

[0135] The receiving identification of at least one partition set in the plurality of partition sets matches the sending identification of the third partition set.

[0136] It can be seen that in the embodiments of the present application, part of the partition sets in the second partition set can be related to the third partition set, or all the partition sets in the second partition set can be related to the third partition set, which is not limited in the embodiments of the present application.

[0137] If only part of the partition sets in the plurality of partition sets have the receiving identification matching the sending identification of the third partition set, updating the information of the first node in the second switching device according to the first message can include:

[0138] According to the information corresponding to the matching successful sending identification in the first message, the information of the node corresponding to the matching successful receiving identification in the second switching device is updated.

[0139] In some embodiments, the first switching device and the second switching device can also perform corresponding information interaction based on the related configuration information of the partition set, so as to realize data synchronization of the related configuration information in each switching device.

[0140] The scheme of the corresponding information interaction between the first switching device and the second switching device based on the related configuration information of the partition set is introduced below.

[0141] The second switching device can store the second configuration information of the second partition set. The second configuration information can include the identification of the partition corresponding to the second partition set, and the information of the node included in the corresponding partition. In this way, the second switching device can determine which partitions are related to the second partition set and which nodes are related to the second partition set according to the second configuration information.

[0142] The first time the second switching device acquires and stores the second configuration information can be considered the first update of that second configuration information by the second switching device. This first update usually occurs before steps 401-402 mentioned above.

[0143] It is evident that there is no temporal constraint between the step of updating the second configuration information and the steps 401-402 mentioned above.

[0144] There are several ways to obtain this second configuration information. Examples are given below.

[0145] 1. In one embodiment, the second configuration information may be configured by the user on the second switching device.

[0146] 2. In one embodiment, the second configuration information is received by the second switching device from other devices such as client terminals.

[0147] 3. In one embodiment, the second configuration information is obtained by the second switching device from the first switching device.

[0148] The following section details the scheme for the second switching device to obtain the second configuration information from the first switching device.

[0149] like Figure 5 As shown, a method for processing information is provided in an embodiment of this application. The method includes steps 501-503.

[0150] Step 501: The first switching device sends a configuration message to the second switching device.

[0151] The configuration message includes the sending identifier of the first partition set and the first configuration information of the first partition set.

[0152] In this embodiment of the application, the user can input the configuration information in the first switching device, or the user can transmit the configuration information to the first switching device through other devices such as a user terminal.

[0153] In some examples, the first switching device can be an aggregation switching device or a core switching device, and the second switching device can be an access switching device.

[0154] Step 502: The second switching device receives the configuration message sent by the first switching device.

[0155] Step 503: When the sending identifier of the first partition set matches the receiving identifier of the second partition set, the second switching device updates the second configuration information of the second partition set according to the configuration message.

[0156] The second configuration information includes the identifier of the partition corresponding to the second partition set, as well as the information of the nodes included in the corresponding partition.

[0157] In the embodiments of the present application, the receiving identifiers of the second partition set can be pre-stored in the second switching device, so that the second switching device can identify whether the received message is related to the second partition set according to the sending identifier in the received message. The pre-stored receiving identifiers of the second partition set in the second switching device can be configured manually on the second switching device, or received by the second switching device from other devices such as a client terminal.

[0158] In addition, in some examples, the first switching device and the second switching device can also pre-store respective switching device configuration information.

[0159] The switching device configuration information can include the IP address of the switching device, the local port address of the Transmission Control Protocol (TCP), and device role information. The device role information is used to indicate that the corresponding switching device is a switching device in a single switching device network, a reflector, or a reflector client.

[0160] After receiving the configuration information sent by the first switching device, the second switching device can match the sending identifiers of the first partition set with the receiving identifiers of the second partition set. In some examples, the first partition set can include multiple partition sets, and therefore, there can be multiple sending identifiers in the first partition set. At this time, when at least one sending identifier in the first partition set matches the receiving identifier of the second partition set, the second switching device can update the second configuration information of the second partition set according to the information corresponding to the matched sending identifier in the configuration information.

[0161] In some examples, when the sending identifiers of the first partition set do not match the receiving identifiers of the second partition set, the second switching device does not process the configuration message, that is, does not perform corresponding operations according to the content of the configuration information.

[0162] The following describes the configuration information and the second configuration information of the second switching device with a specific example.

[0163] In an example, the basic information of the respective corresponding partition set can be pre-configured in the first switching device and the second switching device, which can include the sending identifier and the receiving identifier of the corresponding partition set, and in addition, at least one of the name and the description information of the corresponding partition set.

[0164] In addition, the first switching device can acquire first configuration information, which can include an identifier of a partition corresponding to the first set of partitions, and information of nodes included in the partition corresponding to the first set of partitions.

[0165] The specific form of the first configuration information can be various, which is not limited herein. For example, the first configuration information can be stored by one or more table items.

[0166] For example, the first configuration information can include multiple groups of data, and each group of data stores different information by a corresponding data structure.

[0167] In an example, the first switching device can store, by a data structure 1, basic information of any one of the first set of partitions, an identifier of a partition corresponding to the first set of partitions, and an identifier of a node included in the partition corresponding to the first set of partitions.

[0168] One setting mode of the data structure 1 is shown in Table 1.

[0169] Table 1: One setting mode of the data structure 1

[0170]

[0171] In addition, the first switching device can store, by a data structure 2, an association relationship between each partition and node. One setting mode of the data structure 2 is shown in Table 2.

[0172] Table 2: One setting mode of the data structure 2

[0173]

[0174] When a node is added to each partition, the information of the corresponding node is added in the corresponding data structure 2; when a node is deleted from each partition, the information of the corresponding node is deleted in the corresponding data structure 2.

[0175] In the second switching device, the storage mode of the second configuration information of the second set of partitions can refer to the storage modes in Tables 1-2 above, which will not be repeated here.

[0176] In the embodiments of the present application, the second configuration information usually has a large amount of data and can be dynamically adjusted by the user according to the situation. If it is configured and deployed for each switching device, the labor cost and time cost are high. Therefore, in the embodiments of the present application, the first switching device can first acquire the configuration information, then the first switching device sends the configuration information to the second switching device, and the second switching device identifies the relevant information based on the stored receiving identifier to update the second configuration information, so as to improve the updating efficiency of the configuration information. In one scenario, when the first switching device is a reflector, the configuration information can be sent to the plurality of reflector clients connected to the first switching device, so as to realize efficient updating of the corresponding configuration information of the plurality of reflector clients.

[0177] In some embodiments, the first switching device and the second switching device can also perform corresponding information interaction based on the state change information of the nodes, so as to realize data synchronization of the relevant state change information in the switching devices.

[0178] The scheme of the information interaction between the first switching device and the second switching device based on the state change information of the nodes will be introduced below.

[0179] As shown in FIG. 6, in some embodiments, the method can include: Figure 6

[0180] Step 601: The second switching device acquires the state change information of the second node associated with the second switching device.

[0181] Step 602: The second switching device sends a second message to the first switching device.

[0182] The second message includes the state change information of the second node and the sending identifier of the fourth partition set corresponding to the second node, and the fourth partition set belongs to the second partition set.

[0183] The state change information can include the change information of the association state of the second node and the second switching device, which can be described by the state of the second node. The state changes from active to inactive, indicating that the second node accesses the second switching device for the first time or changes from the disconnected state to the re-accessed state of the second switching device; or the state changes from active to inactive, indicating that the second node and the second switching device change from the connected state to the disconnected state.

[0184] ​The second exchange device can obtain the state change information of the associated second node by monitoring the change of the relevant interface of the second node, or receive the state change information sent by the second node. After the second exchange device obtains the state change information of the second node associated with the second exchange device, the second exchange device can send the state change information and the sending identifier of the fourth partition set corresponding to the second node to the first exchange device, so that the first exchange device can be informed of the state change information of the second node and the sending identifier of the fourth partition set associated with the second node through the second exchange device. The sending identifier of the fourth partition set corresponding to the second node can enable the receiver to identify the fourth partition set associated with the second message.

[0185] In some examples, after obtaining the state change information of the associated second node, the second exchange device can further query the information of the partition to which the second node belongs. If there is another node in addition to the second node connected to the second exchange device in the partition to which the second node belongs, the second exchange device can further send the state change information of the second node to the other node, so that the other node determines the subsequent information interaction operation based on the received state change information.

[0186] In some embodiments, the method further comprises:

[0187] Step 603, the first exchange device receives the second message.

[0188] Step 604, when the sending identifier of the fourth partition set matches the receiving identifier of the first partition set, the first exchange device updates the information of the second node in the first exchange device according to the state change information of the second node and the sending identifier of the fourth partition set.

[0189] In this way, the first exchange device can determine the fourth partition set associated with the second node in the second message through the sending identifier in the second message, so as to determine whether the fourth partition set is the partition set associated with the first exchange device, and further determine whether information update in the first exchange device is needed based on the second message. This can reduce the amount of irrelevant data stored in the first exchange device and waste of storage resources.

[0190] In some embodiments, the method further comprises:

[0191] Step 605, the first exchange device generates a third message.

[0192] The third message includes the state change information of the second node and the sending identifier of the fourth partition set.

[0193] Step 606, the first exchange device sends the third message to other exchange devices connected to the first exchange device except the second exchange device.

[0194] The first switching device can determine, through the operation of the source, other switching devices connected to the first switching device except the second switching device before sending the third message, so as to send the third message to other switching devices connected to the first switching device except the second switching device, so that the corresponding other switching devices perform corresponding processing according to the third message. For example, a certain other switching device can judge whether the sending identifier carried in the third message matches the receiving identifier of the partition set corresponding to the other switching device, and if so, update the information of the related node in the other switching device according to the third message, so as to realize the data synchronization of the state change information of the related node between each associated switching device in the network system through the first switching device.

[0195] The time sequence relationship between the above steps 601-606 and the above steps 401-402 is not limited here.

[0196] In the above embodiment, the message interaction mechanism for establishing a connection between the first switching device and the second switching device can be based on a traditional mechanism, or can be adjusted based on the related content of the above embodiment on the basis of the traditional mechanism. In some examples, the message type transmitted between the first switching device and the second switching device includes one or more of OPEN, UPDATE, NOTIFICATION, and KEEPALIVE. The UPDATE message can be used to send the first message, the second message, and the third message described above.

[0197] An exemplary message format of the UPDATE message is described as shown in Table 3.

[0198] Table 3: An exemplary message format of the UPDATE message

[0199]

[0200] TLV refers to tag-length-value. Table 3 only shows a part of the UPDATE message as an example, and does not include all message types of the UPDATE message.

[0201] When the switching device announces the addition, modification, or deletion of the related partition configuration information to other switching devices, the switching device can generate the content of the message based on the message format shown in Table 4. The message can be the UPDATE message of message type 11 or message type 12 in Table 3.

[0202] Table 4: An exemplary message format of the message about partition configuration information

[0203]

[0204] When the exchange device advertises the state change information of the related node to other exchange devices, the exchange device can generate the content of the message based on the message format shown in Table 5. The message can be an UPDATE message of the message type 13 or the message type 14 in Table 3.

[0205] Table 5: An exemplary message format of the message about the state change information

[0206]

[0207] In some embodiments, the first exchange device is a first reflector, the second exchange device is a reflector client, and the network system further includes a third exchange device, the third exchange device is a second reflector, and the first reflector and the second reflector correspond to different sets of partitions.

[0208] The reflector can be connected with one or more reflector clients and can acquire information sent by each connected reflector client and send the information to other reflector clients except the source side, so as to realize data synchronization between the exchange devices. In this way, the reflector clients do not need to establish a connection one by one to deliver information. Of course, in the embodiments of the present application, the connection relationship between the reflector clients is not limited, and the reflector clients connected with the same reflector can also establish a connection based on the needs of some scenarios. Generally, based on the function of the reflector, the aggregation exchange device and / or the core exchange device in the network system can be regarded as the reflector, and the corresponding access exchange device can be regarded as the reflector client.

[0209] In the embodiments of the present application, the network system includes the first exchange device as the first reflector and the third exchange device as the second reflector, and the first reflector and the second reflector correspond to different sets of partitions. In this way, the related node information and the related configuration information of different sets of partitions can be stored in different reflectors respectively, so as to avoid the problem that a single reflector in the network system needs to store and process a large amount of information of the sets of partitions, thereby realizing load sharing in the network system.

[0210] In some embodiments, the network system is a storage area network (SAN), the plurality of nodes include computing nodes and storage nodes, the network system includes a first subsystem and a second subsystem, the first subsystem includes the first exchange device and the second exchange device, the second subsystem includes the third exchange device, and the storage nodes corresponding to the first subsystem and the second subsystem are backup to each other.

[0211] In this embodiment, SAN is a dedicated high-speed network connecting compute nodes and storage nodes. The compute nodes and storage nodes of the SAN can form a dedicated network for data storage. In this way, a data center can be formed through the SAN, thereby providing storage, transmission, and other processing of business data from the nodes for practical application scenarios.

[0212] As business scale continues to grow, the resources of a single data center are no longer sufficient to meet business needs in real-world application scenarios. In addition, data disaster recovery has gradually become a common requirement due to considerations such as data security and business reliability. Therefore, multiple data centers can be established to support business and perform data backup to achieve data disaster recovery.

[0213] Based on the above requirements, in some examples, multiple data centers can be established to handle related business processing, improve the processing capacity of business data, and perform data disaster recovery backup.

[0214] For example, two data centers can form a dual-active data center, meaning that both data centers are active, peer-to-peer, without master-slave distinction, and can deploy services simultaneously. Data synchronization between the two data centers can be performed according to specified rules based on business scenarios. Of course, in other examples, the storage system may also include one data center, three data centers, or other numbers of data centers. This application does not impose any limitations on these embodiments.

[0215] In this embodiment, the network system may include a first subsystem and a second subsystem. The storage nodes corresponding to the first and second subsystems serve as backups for each other. The reflector in the first subsystem includes a first switching device, and the reflector in the second subsystem includes a third switching device. Thus, the first and second subsystems are located in different data centers. Furthermore, the reflectors in the different subsystems are different, allowing each subsystem to use a different reflector to handle the collection and transmission of relevant configuration information and node information between switching devices. This rationally allocates device resources and achieves load balancing among switching devices across multiple data centers.

[0216] like Figure 7 The diagram shown is an exemplary structural diagram of a switching device and related nodes. Figure 7 The diagram illustrates the relationships between various switching devices and nodes.

[0217] based on Figure 7 The relationships between the various switching devices and nodes in the system. Figure 7 The nodes shown form at least the following partitions:

[0218] Partition c1 : compute node 701, storage node 721, storage node 722;

[0219] Partition c2: compute node 702, storage node 721, storage node 722;

[0220] Partition c3: compute node 703, storage node 721, storage node 722;

[0221] Partition c4: compute node 701, storage node 723, storage node 724;

[0222] Partition c5: compute node 702, storage node 723, storage node 724;

[0223] Partition c6: compute node 703, storage node 723, storage node 724;

[0224] Partition c7: compute node 704, storage node 721, storage node 722;

[0225] Partition c8: compute node 705, storage node 721, storage node 722;

[0226] Partition c9: compute node 706, storage node 721, storage node 722;

[0227] Partition c10: compute node 704, storage node 723, storage node 724;

[0228] Partition c11 : compute node 705, storage node 723, storage node 724;

[0229] Partition c12: compute node 706, storage node 723, storage node 724.

[0230] From the partitions c1 -c12, a set of partitions C1 -C4 can be obtained, wherein:

[0231] Set of partitions C1 : partition c1, partition c2 and partition c3;

[0232] Set of partitions C2: partition c4, partition c5 and partition c6;

[0233] Set of partitions C3: partition c7, partition c8 and partition c9;

[0234] Set of partitions C4: partition c10, partition c11 and partition c12.

[0235] In Figure 7In the example shown, the data center 70 and the data center 71 are connected through a dual-active network to realize information interaction, so as to realize information synchronization between the first subsystem and the second subsystem. Specifically, the aggregation switch device 712, the first switch device 713 of the first subsystem, and the third switch device 716, the aggregation switch device 717 of the second subsystem are connected with the dual-active network to realize data transmission across data centers. The dual-active network can include one or more switch devices.

[0236] Figure 7 In the example shown, the aggregation switch device 712, the first switch device 713, the third switch device 716, and the aggregation switch device 717 are respectively associated with four partition sets, i.e., the partition set C1, the partition set C2, the partition set C3, and the partition set C4. Figure 7 In the example shown, each partition set can be associated with two reflectors. Specifically, the partition set C1 is associated with the aggregation switch device 712 and the first switch device 713, the partition set C2 is associated with the first switch device 713 and the third switch device 716, the partition set C3 is associated with the aggregation switch device 712 and the aggregation switch device 717, and the partition set C4 is associated with the third switch device 716 and the aggregation switch device 717. In this way, data disaster recovery can be realized for each partition set, and disaster recovery backup between the data center 70 and the data center 71 is realized, avoiding the failure of a single reflector to cause the transmission of the intercommunication data of the related nodes of the corresponding partition set to be impossible, and improving the reliability of the system.

[0237] However, with the increase of the reflectors, the information of the related nodes and the related configurations stored in each switch device in the traditional scheme is doubled, thereby a large amount of storage resources needs to be consumed.

[0238] In the example shown, each switch device only needs to store the information of the related nodes and the related configurations of the related partition set, so as to meet the corresponding operation needs, and a large amount of irrelevant data storage is reduced, and the waste of storage resources is reduced.

[0239] In the example shown, the number of the partition sets related to each reflector and the reflector client is equal, so that load sharing between each switch device can be realized. Figure 8

[0240] In addition, in the example shown, the first switch device only needs to store the related node information and the related configuration information of the partition set C1 and the partition set C2, and does not need to store all the node information and the configuration information of all the partitions c1-c12 globally, thereby compared with the traditional scheme, the consumption of the storage resources is greatly reduced.
