[0027] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0028] The present invention discloses an IP address allocation method, device and equipment for edge computing scenarios, which are applied to technical fields such as edge computing, data centers and servers in the field of cloud computing to achieve the purpose of accurately allocating IP addresses.

[0029] In the technical solution of the present disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0030] First, some technical terms involved in this disclosure are explained:

[0031] IP Address Management (IPAM) is a comprehensive IP address management system used for IP address pool management and automated IP allocation and recycling.

[0032] Dynamic Host Configuration Protocol (DHCP) is a network protocol used to automatically apply for IP addresses and other network configuration parameters such as virtual local area networks (VLANs) for devices such as server network cards. It relies on the existence and management of IPAM.

[0033] DHCP relay is a function of a network device (usually a router or switch) that is used to forward DHCP messages across the Layer 2 network between different subnets.

[0034] The dual uplink network architecture is a network connection mode that uses two DHCP relay devices (such as switches) to provide two independent links to connect network devices to improve network reliability and performance.

[0035] Gateway IP address (GIADDR), in the DHCP protocol, GIADDR is the IP address of the relay agent, specifically the gateway address of the DHCP relay device, which is used to identify the network device that forwards DHCP requests.

[0036] The DHCP relay agent information option (Option 82) is an extended option in the DHCP protocol. It can be freely extended and configured and is added to the DHCP discovery message by the DHCP relay agent (DHCP relay device).

[0037] In the edge computing network architecture, in order to solve the network management problem of a large number of edge computing edge nodes (i.e. edge servers), IP allocation and management are usually performed for all edge servers through a centralized IPAM server. The edge servers that apply for IP addresses are scattered in the computer rooms of each edge computing node, and the IPAM server is located on the centralized central cloud. The edge servers and IPAM servers interact through the public network.

[0038] At present, when dynamic IP address allocation is performed across the Layer 2 network through an IPAM server, the DHCP Relay mechanism is relied upon. Among them, the GIADDR field in the DHCP message is usually filled with the gateway address of the DHCP relay device to mark the source of the DHCP message. The relay of the DHCP message must be forwarded to the IPAM server through the upstream DHCP relay device (such as a switch), so that the IPAM server can allocate an IP address to the edge server based on the gateway address of the DHCP relay device. However, for the network architecture with dual upstream DHCP relay devices, in order to achieve high availability, the gateway addresses of the DHCP relay devices in the dual upstream network architecture are usually the same, resulting in the IPAM server being unable to accurately locate the target DHCP relay device when replying to the DHCP provision message. Therefore, there is a problem of probabilistic failure in allocating IP addresses through the above method, which leads to the risk of IP address allocation failure. This problem seriously restricts the reliability and flexibility of modern network infrastructure.

[0039] For example, Figure 1 FIG. 1 is a schematic diagram of an IP address allocation method provided by related technologies. Figure 1As shown, in the edge computing network architecture, taking the DHCP relay device as the first switch and the second switch as an example, the first switch and the second switch are a dual uplink network architecture, the first switch is connected to the first network card (eth0) of the edge server, and the second switch is connected to the second network card (eth1) of the edge server. The IP address allocation method provided by the related technology may include:

[0040] S101. When the edge server is started, the DHCP client on the first network card (eth0) of the edge server sends a DHCP discovery message in a broadcast manner.

[0041] Correspondingly, the first switch connected to the edge server receives the DHCP discovery message sent by the edge server.

[0042] S102. The first switch fills the gateway address of the first switch into the GIADDR field of the DHCP discovery message, and relays the DHCP discovery message filled with the gateway address of the first switch to the IPAM server located in the cloud center through the gateway via the public network.

[0043] Correspondingly, the IPAM server receives the DHCP discovery message.

[0044] It can be understood that the gateway address of the first switch is the same as the gateway address of the second switch, for example, both are: xxx1.

[0045] S103, the IPAM server parses the received DHCP discovery message, allocates a target IP address to the edge server according to the gateway address, and sends a DHCP offer message according to the gateway address, wherein the DHCP offer message includes the target IP address.

[0046] Since the gateway address of the first switch is the same as the gateway address of the second switch, the first switch may receive the DHCP offer message, or the second switch may receive the DHCP offer message, resulting in the DHCP offer message being probabilistically successfully sent to the first switch, and then the edge server probabilistically successfully obtains the target IP address.

[0047] refer to Figure 1 , in a single uplink physical network architecture, Figure 1 There is no probabilistic failure problem when allocating IP addresses in the process. However, in order to pursue network link redundancy and service reliability, a dual-uplink switch network architecture is usually used. Since the gateway addresses of the dual-uplink switches are the same, when the IPAM server replies to the gateway address with a DHCP offer message, the DHCP offer message cannot determine which dual-uplink switch to reply to, resulting in a probabilistic failure problem in IP address allocation.

[0048] In order to solve the above problems, the present disclosure provides an IP address allocation method for edge computing scenarios. After receiving the DHCP discovery message sent by the edge server, the DHCP relay device fills the loopback address and gateway address of the DHCP relay device into the DHCP discovery message, so that the IPAM server allocates the target IP address to the edge server according to the gateway address in the DHCP discovery message, and sends a DHCP offer message containing the target IP address to the DHCP relay device according to the loopback address in the DHCP discovery message. Since the loopback address of the DHCP relay device is unique, the IPAM server can accurately route the DHCP offer message to the DHCP relay device corresponding to the loopback address, so that the edge server accurately obtains the target IP address, which can avoid the problem of probabilistic failure when allocating IP addresses.

[0049] It can be seen that the IP address allocation method for edge computing scenarios provided by the present disclosure is aimed at the dual-uplink network architecture of the edge node (edge ​​server) in the edge computing scenario, providing an efficient network resource management solution for enterprise data centers and cloud computing infrastructure, and realizing accurate positioning of network topology and intelligent allocation of dynamic IP addresses. Among them, combined with the dynamic network environment, it can realize automatic identification of subnets and topologies, accurate allocation of IP addresses, and rapid adaptation to complex network scenarios, providing efficient network resource management support for edge computing scenarios, and is suitable for the construction and operation and maintenance of complex network environments in enterprise data centers, cloud computing infrastructure and edge computing scenarios.

[0050] Figure 2 It is a schematic diagram of an application scenario applicable to the IP address allocation method for edge computing scenarios disclosed in the present invention. The application scenario may include: an edge server, a first DHCP relay device connected to the first network card of the edge server, a second DHCP relay device connected to the second network card of the edge server, and an IPAM server. After receiving the DHCP discovery message sent by the DHCP client on the first network card of the edge server, the first DHCP relay device fills the loopback address and gateway address of the first DHCP relay device into the DHCP discovery message, so that the IPAM server allocates a target IP address to the edge server according to the gateway address in the DHCP discovery message, and sends a DHCP offer message containing the target IP address to the first DHCP relay device according to the loopback address in the DHCP discovery message; the first DHCP relay device sends a DHCP offer message to the edge server, and the edge server obtains the target IP address from the DHCP offer message.

[0051] It should be noted that Figure 2 This is only a schematic diagram of an application scenario provided by the embodiment of the present disclosure. Figure 2 does not limit the equipment included in Figure 2 The positional relationship between the devices is limited.

[0052] The following specific embodiments are used to describe in detail the technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0053] Figure 3 Schematic diagram of the first embodiment of the present disclosure. Figure 3 As shown, the IP address allocation method for edge computing scenarios provided by the first embodiment of the present disclosure is applied to DHCP relay devices and IPAM servers in edge computing network architecture. The IP address allocation method for edge computing scenarios provided by the first embodiment of the present disclosure includes:

[0054] S301: A DHCP relay device receives a DHCP discovery message sent by an edge server.

[0055] In the disclosed embodiment, the DHCP relay device is, for example, a switch or a router. Exemplarily, in an edge computing network architecture, the edge server sends a DHCP discovery (DISCOVER) message, for example, in a broadcast manner. A DHCP relay device that is connected to the edge server in communication can receive a DHCP discovery message sent by the edge server. The DHCP discovery message, for example, carries information such as a media access control (MAC) address of a network card of the edge server.

[0056] S302: The DHCP relay device fills the loopback address and gateway address of the DHCP relay device into the DHCP discovery message to obtain a processed message.

[0057] It can be understood that the loopback address of each DHCP relay device is unique. Therefore, different DHCP relay devices can be distinguished by the loopback address to ensure that the DHCP response message (such as the DHCP offer message) can be accurately routed to the DHCP relay device corresponding to the loopback address. Exemplarily, the DHCP relay device can fill the loopback address of the DHCP relay device into the gateway IP address (GIADDR) field of the DHCP discover message; the DHCP relay device can fill the gateway address of the DHCP relay device into the DHCP relay agent information option (Option 82) of the DHCP discover message, thereby obtaining a processed message, which is the processed DHCP discover message.

[0058] S303. The DHCP relay device sends the processed message to the IPAM server to obtain a DHCP provision message sent by the IPAM server.

[0059] Correspondingly, the IPAM server receives the DHCP discovery message (ie, the processed message) sent by the DHCP relay device.

[0060] Exemplarily, after obtaining the processed message (ie, the processed DHCP discovery message), the DHCP relay device sends the processed message to the IPAM server to obtain a DHCP offer (OFFER) message sent by the IPAM server.

[0061] S304. The IPAM server allocates a target IP address to the edge server according to the gateway address.

[0062] Exemplarily, referring to the example of step S302, after receiving the DHCP discovery message (i.e., the processed message) sent by the DHCP relay device, the IPAM server can parse the Option 82 option of the DHCP discovery message to obtain the gateway address of the DHCP relay device, thereby allocating a target IP address to the edge server based on the gateway address.

[0063] S305. The IPAM server sends a DHCP offer message to the DHCP relay device according to the loopback address, and the DHCP offer message includes the target IP address.

[0064] Correspondingly, the DHCP relay device receives the DHCP offer message sent by the IPAM server.

[0065] Exemplarily, referring to the example of step S302, after receiving the DHCP discovery message (i.e., the processed message) sent by the DHCP relay device, the IPAM server can parse the GIADDR field of the DHCP discovery message to obtain the loopback address of the DHCP relay device. According to the protocol specification of DHCP Relay, the DHCP offer message will be replied to the address specified in the GIADDR field, and the loopback address of the DHCP relay device is unique. Therefore, a DHCP offer message can be sent to the DHCP relay device corresponding to the loopback address, so as to correctly route the DHCP offer message to the DHCP relay device that sent the DHCP discovery message. Among them, the DHCP offer message includes the target IP address assigned to the edge server, and can also include information such as the mask address, gateway address, and timeliness of the target IP address.

[0066] S306: The DHCP relay device sends a DHCP offer message to the edge server.

[0067] Correspondingly, the edge server receives the DHCP offer message sent by the DHCP relay device.

[0068] In this step, after receiving the DHCP offer message sent by the IPAM server, the DHCP relay device sends the DHCP offer message to the edge server. Correspondingly, the edge server receives the DHCP offer message sent by the DHCP relay device, parses the DHCP offer message, and obtains the target IP address.

[0069] In the disclosed embodiment, after receiving the DHCP discovery message sent by the edge server, the DHCP relay device fills the loopback address and gateway address of the DHCP relay device into the DHCP discovery message, obtains a processed message, and sends the processed message to the IPAM server; thereby, the IPAM server allocates a target IP address to the edge server according to the gateway address, and sends a DHCP offer message to the DHCP relay device according to the loopback address, and the DHCP offer message includes the target IP address; the DHCP relay device sends the DHCP offer message to the edge server. Since the loopback address of the DHCP relay device is unique, it can ensure that the IPAM server accurately routes the DHCP offer message to the DHCP relay device corresponding to the loopback address, so that the edge server accurately obtains the target IP address, realizes the precise positioning of the network topology and the intelligent allocation of dynamic IP addresses, avoids the problem of probabilistic failure when allocating IP addresses, and facilitates seamless integration with existing network devices and protocols while ensuring that the basic specifications of the original DHCP protocol remain unchanged.

[0070] Figure 4 Schematic diagram of the second embodiment of the present disclosure. Based on the above embodiment, the present disclosure further describes the IP address allocation method for edge computing scenarios. Figure 4 As shown, the IP address allocation method for edge computing scenarios provided by the second embodiment of the present disclosure may include:

[0071] S401: A DHCP relay device receives a DHCP discovery message sent by an edge server.

[0072] The implementation principle and technical effect of S401 can be referred to the above Figure 3 The embodiment of step S301 is not described in detail.

[0073] In the disclosed embodiment, Figure 3 The step S302 may further include the following step S402:

[0074] S402: The DHCP relay device fills the loopback address of the DHCP relay device into the gateway IP address field of the DHCP discover message, and fills the gateway address of the DHCP relay device into the DHCP relay agent information option of the DHCP discover message to obtain a processed message.

[0075] Exemplarily, after receiving the DHCP discovery message sent by the edge server, the DHCP relay device fills the loopback address of the DHCP relay device into the GIADDR field of the DHCP discovery message, and fills the gateway address of the DHCP relay device into the Option82 option of the DHCP discovery message to obtain a processed message. It can be understood that the embodiment of the present disclosure replaces the gateway address of the DHCP relay device in the current related technology with the loopback address of the DHCP relay device, and fills it into the DHCP discovery message as a unique GIADDR identifier to ensure the accurate routing of the DHCP OFFER message; and extends the OPTION82 option in the DHCP protocol, embeds more network topology information, carries the gateway address of the DHCP relay device in the OPTION82 option, and uses the gateway address for the allocation of IP addresses. Under the condition of ensuring that the basic specifications of the original DHCP protocol remain unchanged, the additional information transmission of the subnet is realized by extending the OPTION82 option, which is convenient for seamless integration with existing network devices and protocols.

[0076] Optionally, filling the gateway address of the DHCP relay device into the DHCP relay agent information option of the DHCP discover message may include: filling the gateway address of the DHCP relay device into the DHCP relay agent information option of the DHCP discover message according to a preset protocol format.

[0077] Exemplarily, the information and format of the OPTION82 option can be pre-agreed between the DHCP relay device and the IPAM server, so that the gateway address of the DHCP relay device can be filled into the OPTION82 option of the DHCP discovery message according to the preset protocol format, thereby facilitating the IPAM server to parse the OPTION82 option according to the preset protocol format to obtain the gateway address.

[0078] S403. The DHCP relay device sends the processed message to the IPAM server to obtain a DHCP provision message sent by the IPAM server.

[0079] Correspondingly, the IPAM server receives the DHCP discovery message (ie, the processed message) sent by the DHCP relay device.

[0080] The implementation principle and technical effect of S403 can be referred to the above Figure 3Optionally, in the DHCP discovery message received by the IPAM server, the loopback address is filled in the gateway IP address field of the DHCP discovery message, and the gateway address is filled in the DHCP relay agent information option of the DHCP discovery message.

[0081] It can be understood that when the DHCP relay device sends a DHCP discovery message to the IPAM server, it fills the loopback address of the DHCP relay device into the gateway IP address field of the DHCP discovery message, and fills the gateway address of the DHCP relay device into the DHCP relay agent information option of the DHCP discovery message. Therefore, in the DHCP discovery message received by the IPAM server, the loopback address is filled in the gateway IP address field of the DHCP discovery message, and the gateway address is filled in the DHCP relay agent information option of the DHCP discovery message.

[0082] In the disclosed embodiment, Figure 3 The step S304 may further include the following three steps S404 to S406:

[0083] S404. The IPAM server parses the DHCP relay agent information option according to a preset protocol format to obtain a gateway address.

[0084] Exemplarily, the preset protocol format is the information and format of the OPTION82 option pre-agreed between the DHCP relay device and the IPAM server. Therefore, the IPAM server can parse the DHCP relay agent information option according to the preset protocol format to obtain the gateway address. It can be understood that after receiving the DHCP discovery message (i.e., the processed message) sent by the DHCP relay device, the IPAM server no longer relies on the traditional GIADDR field in the DHCP discovery message to locate the subnet and allocate the IP address, but parses the content in the DHCP OPTION82 option according to the agreed preset protocol format, and extracts the gateway address of the subnet of the IPAM server. Based on the key field of the gateway address, the IPAM server can complete the allocation of IP addresses at the central end.

[0085] S405. The IPAM server queries the subnet gateway address in the IPAM server according to the gateway address, and determines the target subnet corresponding to the gateway address.

[0086] Exemplarily, the IPAM server matches the gateway address of the DHCP relay device with all subnet gateway addresses in the IPAM server, and can determine the target subnet corresponding to the gateway address of the DHCP relay device.

[0087] S406. The IPAM server allocates a target IP address to the edge server according to the target subnet.

[0088] Exemplarily, assuming that the gateway address of the DHCP relay device is "100.10.1.1", the network segment of the target subnet corresponding to the gateway address is: from "100.10.1.100" to "100.10.1.200", then the target IP address can be allocated to the edge server from this network segment, and the allocated target IP address is, for example, "100.10.1.101".

[0089] S407. The IPAM server sends a DHCP offer message to the DHCP relay device according to the loopback address, and the DHCP offer message includes the target IP address.

[0090] Correspondingly, the DHCP relay device receives the DHCP offer message sent by the IPAM server.

[0091] The implementation principle and technical effect of S407 can be referred to the above Figure 3 The embodiment of step S305 is not described in detail.

[0092] S408: The DHCP relay device sends a DHCP offer message to the edge server.

[0093] Correspondingly, the edge server receives the DHCP offer message sent by the DHCP relay device.

[0094] The implementation principle and technical effect of S408 can be referred to the above Figure 3 The embodiment of step S306 is not described in detail.

[0095] S409: The DHCP relay device receives a DHCP request message sent by the edge server, where the DHCP request message carries a target IP address.

[0096] In this step, after receiving the DHCP offer message sent by the DHCP relay device, the edge server parses the DHCP offer message to obtain the target IP address. After determining to use the target IP address, the edge server sends a DHCP request (REQUEST) message to the DHCP relay device, and the DHCP request message carries the target IP address.

[0097] S410, the DHCP relay device fills the loopback address of the DHCP relay device into the DHCP request message, obtains the processed DHCP request message, sends the processed DHCP request message to the IPAM server to obtain the DHCP confirmation message sent by the IPAM server, and the processed DHCP request message carries the target IP address and the loopback address of the DHCP relay device.

[0098] Correspondingly, the IPAM server receives the DHCP request message sent by the DHCP relay device.

[0099] Exemplarily, after receiving the DHCP request message sent by the edge server, the DHCP relay device fills the loopback address of the DHCP relay device into the gateway IP address (GIADDR) field of the DHCP request message to ensure the accurate routing of the DHCP confirmation message. The DHCP relay device sends a DHCP request message to the IPAM server, and the DHCP request message carries the target IP address and the loopback address of the DHCP relay device.

[0100] S411. The IPAM server confirms that the target IP address is allocated to the edge server according to the DHCP request message sent by the DHCP relay device.

[0101] Exemplarily, after receiving the DHCP request message sent by the DHCP relay device, the IPAM server can confirm the allocation of the target IP address to the edge server, for example, by updating the usage status of the target IP address.

[0102] S412. The IPAM server sends a DHCP confirmation message according to the loopback address.

[0103] Correspondingly, the DHCP relay device receives the DHCP confirmation message sent by the IPAM server.

[0104] In this step, after confirming that the target IP address is assigned to the edge server, the IPAM server sends a DHCP confirmation message according to the loopback address.

[0105] S413: The DHCP relay device sends a DHCP confirmation message to the edge server, where the DHCP confirmation message is used to instruct the edge server to confirm the use of the target IP address.

[0106] Correspondingly, the edge server receives the DHCP confirmation message sent by the DHCP relay device.

[0107] In this step, after receiving the DHCP confirmation message sent by the IPAM server, the DHCP relay device sends a DHCP confirmation message to the edge server. After receiving the DHCP confirmation message, the edge server confirms to use the target IP address.

[0108] In the disclosed embodiment, after receiving the DHCP discover message sent by the edge server, the DHCP relay device fills the loopback address of the DHCP relay device into the gateway IP address field of the DHCP discover message, and fills the gateway address of the DHCP relay device into the DHCP relay agent information option of the DHCP discover message, and sends the processed DHCP discover message to the IPAM server; thereby, the IPAM server allocates a target IP address to the edge server according to the gateway address, and sends a DHCP offer message to the DHCP relay device according to the loopback address, and the DHCP offer message includes the target IP address; the DHCP relay device sends the DHCP offer message to the edge server; and then based on the target IP address and the loopback address in the gateway IP address field, the interaction of the DHCP request message and the DHCP confirmation message is completed.

[0109] Figure 5 is a schematic diagram according to the third embodiment of the present disclosure. Figure 5 As shown, the IP address allocation method for edge computing scenarios provided by the third embodiment of the present disclosure is applied to a DHCP relay device in an edge computing network architecture. The IP address allocation method for edge computing scenarios provided by the third embodiment of the present disclosure includes:

[0110] S501: Receive a DHCP discovery message sent by an edge server.

[0111] In the disclosed embodiment, the DHCP relay device is, for example, a switch or a router. Exemplarily, in an edge computing network architecture, the edge server sends a DHCP discovery (DISCOVER) message, for example, in a broadcast manner. A DHCP relay device connected to the edge server receives a DHCP discovery message sent by the edge server. The DHCP discovery message carries, for example, information such as the MAC address of the network card of the edge server.

[0112] S502: Fill the loopback address and gateway address of the DHCP relay device into the DHCP discovery message to obtain a processed message.

[0113] Exemplarily, the loopback address of the DHCP relay device can be filled into the gateway IP address (GIADDR) field of the DHCP discover message, and the gateway address of the DHCP relay device can be filled into the DHCP relay agent information option (Option82) of the DHCP discover message, thereby obtaining a processed message, which is a processed DHCP discover message.

[0114] S503. Send the processed message to the IPAM server to obtain a DHCP offer message sent by the IPAM server. The IPAM server is used to allocate a target IP address to the edge server according to the gateway address, and send a DHCP offer message according to the loopback address. The DHCP offer message includes the target IP address.

[0115] It can be understood that the gateway address is used to assign a target IP address to the edge server, and the loopback address is used to send a DHCP response message, such as the DHCP offer message in this step.

[0116] S504: Send a DHCP offer message to the edge server.

[0117] In the disclosed embodiment, after receiving the DHCP discovery message sent by the edge server, the loopback address and gateway address of the DHCP relay device are filled into the DHCP discovery message to obtain a processed message, and the processed message is sent to the IPAM server, so that the IPAM server allocates a target IP address to the edge server according to the gateway address, and sends a DHCP offer message according to the loopback address. The DHCP offer message includes the target IP address, and the DHCP relay device sends the DHCP offer message to the edge server. Since the loopback address of the DHCP relay device is unique, it can ensure that the IPAM server accurately routes the DHCP offer message to the DHCP relay device corresponding to the loopback address, so that the edge server accurately obtains the target IP address, avoiding the problem of probabilistic failure when allocating IP addresses.

[0118] Figure 6 is a schematic diagram according to the fourth embodiment of the present disclosure. Figure 6 As shown, the IP address allocation method for edge computing scenarios provided by the fourth embodiment of the present disclosure is applied to an IPAM server in an edge computing network architecture. The IP address allocation method for edge computing scenarios provided by the fourth embodiment of the present disclosure includes:

[0119] S601. Receive a DHCP discover message sent by a DHCP relay device. The DHCP discover message is a processed message obtained by filling the loopback address and gateway address of the DHCP relay device into the DHCP discover message sent by the edge server after receiving the DHCP discover message sent by the edge server.

[0120] S602: Allocate a target IP address to the edge server according to the gateway address.

[0121] Exemplarily, after receiving a DHCP discover message (ie, a processed message) sent by a DHCP relay device, the DHCP discover message may be parsed to obtain a gateway address of the DHCP relay device, thereby allocating a target IP address to the edge server according to the gateway address.

[0122] S603: Send a DHCP offer message to the DHCP relay device according to the loopback address, where the DHCP offer message includes a target IP address, and the DHCP relay device is used to send the DHCP offer message to the edge server.

[0123] Exemplarily, after receiving the DHCP discovery message (i.e., the processed message) sent by the DHCP relay device, the IPAM server can parse the GIADDR field of the DHCP discovery message to obtain the loopback address of the DHCP relay device, and then send a DHCP offer message to the DHCP relay device according to the loopback address. The DHCP offer message includes the target IP address, which in turn enables the DHCP relay device to send a DHCP offer message to the edge server. The edge server parses the DHCP offer message to obtain the target IP address.

[0124] In the embodiment of the present disclosure, after receiving the DHCP discovery message sent by the DHCP relay device, the target IP address is allocated to the edge server according to the gateway address, and a DHCP offer message is sent to the DHCP relay device according to the loopback address. The DHCP offer message includes the target IP address, and the DHCP relay device is used to send the DHCP offer message to the edge server. Since the loopback address of the DHCP relay device is unique, it is possible to ensure that the DHCP offer message is accurately routed to the DHCP relay device corresponding to the loopback address, so that the DHCP relay device sends the DHCP offer message to the edge server, so that the edge server accurately obtains the target IP address, avoiding the problem of probabilistic failure when allocating IP addresses.

[0125] Based on the above embodiments, Figure 7 is a schematic diagram according to the fifth embodiment of the present disclosure. Figure 7 As shown, the IP address allocation method for edge computing scenarios provided by the embodiment of the present disclosure is applied to Figure 1In the edge computing network architecture shown. The IP address allocation method for edge computing scenarios provided in the fifth embodiment of the present disclosure may include:

[0126] S701: When the edge server is started, the DHCP client on the first network card (eth0) of the edge server sends a DHCP discovery message in a broadcast manner.

[0127] Correspondingly, the first switch connected to the edge server receives the DHCP discovery message sent by the edge server.

[0128] S702. The first switch fills the loopback address of the first switch into the GIADDR field of the DHCP discovery message, and fills the gateway address of the first switch into the Option 82 option of the DHCP discovery message to obtain a processed message; and relays the processed message to the IPAM server located in the cloud center through the gateway via the public network.

[0129] Accordingly, the IPAM server receives the processed message.

[0130] The loopback address of the first switch is, for example, yyy2, and the loopback address of the second switch is, for example, yyy3. The loopback address of each switch is unique. The gateway address of the first switch and the gateway address of the second switch are, for example, both xxx1.

[0131] S703, the IPAM server parses the processed DHCP discovery message (ie, the processed message), allocates a target IP address to the edge server according to the gateway address, and sends a DHCP offer message to the first switch according to the loopback address, wherein the DHCP offer message includes the target IP address.

[0132] Correspondingly, the first switch receives the DHCP offer message sent by the IPAM server, and sends the DHCP offer message to the edge server (not shown in the figure). The edge server receives the DHCP offer message sent by the first switch, thereby obtaining the target IP address.

[0133] and Figure 1Compared with the related technologies shown in the figure, the embodiment of the present disclosure replaces the gateway address of the switch in the current related technology with the loopback address of the switch, and fills it into the DHCP discovery message as a unique GIADDR identifier to ensure the accurate routing of the DHCP provided message; and extends the OPTION82 option in the DHCP protocol, embeds more network topology information, carries the gateway address of the switch in the OPTION82 option, and uses the gateway address for IP address allocation. While ensuring that the basic specifications of the original DHCP protocol remain unchanged, the additional information transmission of the subnet is realized by extending the OPTION82 option, which facilitates seamless integration with existing network devices and protocols.

[0134] Based on the above embodiments, it can be understood that the IP address allocation method for edge computing scenarios provided by the embodiments of the present disclosure can solve the limitations of the existing DHCP allocation mechanism based on the GIADDR field, especially in applications that require accurate routing of DHCP messages and support for complex subnet allocation scenarios, and provides a more efficient and reliable solution for IP address allocation across DHCP relay devices (such as switches).
