Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of address management, and particularly relates to an address allocation method and device and related equipment. BACKGROUND

[0002] With the IPv4 address pool becoming less and less available, the address usage of IPv6 has become a hard requirement for most enterprises. Since the IPv6 address pool is too large, users do not want the address to change dynamically, so there is a demand to fix the address to facilitate subsequent user address statistics and audit screening.

[0003] Currently, the standard protocol for applying for an IPv6 address is to use a DHCP Unique Identifier (DUID) as a unique identifier. However, DUIDs are variable in some use scenarios and are not variable in others. In actual networks, devices that are variable and devices that are not variable exist in a mixed manner. Thus, it cannot be guaranteed that each device can apply for a fixed IPv6 address. SUMMARY

It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0054] It should be understood that although the terms first, second, third, etc. can be used herein to describe various information, but these information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, the first information can also be called the second information without departing from the scope of the application, and similarly, the second information can also be called the first information. In addition, the word "if" used herein can be interpreted as "when" or "when" or "in response to determining" depending on the context.

[0055] For example, refer to Figure 1 A detailed flowchart of an address allocation method provided by an embodiment of the present application is shown in FIG. 3. The method is applied to an authentication server and includes the following steps:

[0056] Step 100: receiving an authentication message sent by a target terminal, the authentication message carrying a username and a MAC address of the target terminal.

[0057] In the embodiment of the present application, the target message is a charging message. Specifically, after determining that the authentication is successful and applying for an IP address, the target terminal sends a charging message to the authentication server.

[0058] In actual application, when a terminal device joins a local area network, terminal user authentication is required, that is, an authentication request is initiated to an authentication server (such as a 3A server) in the network, and the authentication server performs authorization authentication based on terminal user information.

[0059] Step 110: generating an identifier for uniquely identifying the target terminal based on the username and the MAC address of the target terminal, and generating an association between the MAC address of the target terminal and the identifier.

[0060] Specifically, in the embodiment of the present application, the authentication server records the username, MAC address and IP address of the target terminal, and processes the username and MAC address of the target terminal based on a preset algorithm to generate an identifier (e.g., DUID) for uniquely identifying the target terminal. The value of the DUID generated for each terminal is fixed and unchangeable. The authentication server also establishes an association between the MAC address of the target terminal and the identifier.

[0061] Step 120: receiving a target message sent by the target terminal, the target message carrying the allocated IP address of the target terminal, and generating an association between the IP address and the identifier of the target terminal.

[0062] In actual application, after determining that the authentication is passed, the target terminal sends a DHCP Discover message to query available DHCP servers and request allocation of IP address and other configuration information. After the terminal device is authenticated successfully and obtains the IP address, the terminal device sends a charging message to the authentication server, the charging message including the IP address (e.g., IPv6 address) information applied for by the terminal. After obtaining the IP address of the target terminal, the authentication server establishes an association between the IP address and the identifier of the terminal.

[0063] Step 130: sending the association between the MAC address and the identifier of the target terminal to the DHCP relay device, and sending the association between the IP address and the identifier of the target terminal to the DHCP service.

[0064] Specifically, the authentication server sends the association between the MAC address and the identifier of the target terminal to the DHCP relay device in the network, and simultaneously, the authentication server sends the association between the IP address and the identifier of the target terminal to the DHCP service.

[0065] In this way, the DHCP relay device maintains the association between the MAC address and the identifier of each terminal, and the DHCP server maintains the association between the IP address and the identifier of each terminal allocated with an IP address. When the target terminal is online again, the DHCP relay device can carry the identifier in the address request message carrying the MAC address of the target terminal and send the address request message to the DHCP server, so that the DHCP server determines the associated IP address based on the identifier and allocates the IP address to the target terminal.

[0066] In actual application, when the target terminal is online again, the DHCP relay device receives the DHCP Discover message sent by the target terminal, the DHCP Discover message including the MAC address and the virtual DUID (such as the variable DUID value) of the target terminal, at this time, the DHCP relay device can modify the DUID value in the original message to the value of the identifier corresponding to the MAC address of the target terminal, and then forward to the DHCP server, and the DHCP server judges whether the IP address corresponding to the identifier exists according to the value of the identifier after receiving the DHCP Discover message, if the IP address exists, the IP address is allocated to the target terminal.

[0067] That is, the fixed terminal of the user can obtain the fixed IP address from the DHCP server, and the authentication server can perform more convenient management and control when performing charging / auditing.

[0068] Similarly, referring to Fig. 2, a detailed flowchart of an address allocation method provided by the embodiment of the present application is shown, the method being applied to a DHCP relay device; the method including the following steps: Figure 2 Step 200: receiving the association relationship between the MAC address of the target terminal and the identifier for uniquely identifying the target terminal sent by the authentication server.

[0069] The identifier is generated by the authentication server based on the username and the MAC address of the target terminal.

[0070] Step 210: receiving the address request message carrying the MAC address of the target terminal.

[0071] Step 220: determining the corresponding identifier based on the MAC address of the target terminal, and sending the identifier in the address request message to the DHCP server.

[0072] In this way, the DHCP server determines the associated IP address based on the identifier and the association relationship between the IP address of each terminal and the corresponding identifier sent by the authentication server, and allocates the IP address to the target terminal.

[0073] Similarly, referring to Fig. 3, a detailed flowchart of an address allocation method provided by the embodiment of the present application is shown, the method being applied to a DHCP server; the method including the following steps:

[0074] Figure 3 Step 300: receiving the association relationship between the IP address of the target terminal and the identifier for uniquely identifying the target terminal sent by the authentication server.

[0075] The identifier is generated by the authentication server based on the username and the MAC address of the target terminal.

[0076] ​The identifier is generated by the authentication server based on the username and MAC address of the target terminal.

[0077] Step 310: Receive an address request message sent by the DHCP relay device, wherein the address request message carries the identifier.

[0078] Step 320: Based on the identifier, the authentication server determines the associated IP address by matching the IP address of each terminal with the corresponding identifier, and assigns the IP address to the target terminal.

[0079] The address allocation process provided in this application embodiment will be described in detail below with reference to specific application scenarios. For example, see [link to relevant documentation]. Figure 4 The diagram shown is a schematic representation of a process in which an authentication server, a DHCP relay device, and a DHCP server work together to allocate addresses, according to an embodiment of this application.

[0080] 1. End-user authentication is launched. The user sends an authentication request to the authentication server, and the authentication server successfully authorizes and authenticates the user.

[0081] 2. After successful terminal authentication and address application, the terminal will send an accounting message to the authentication server. The authentication server records the username, terminal MAC address, and IPv6 information carried in the accounting message, and generates a fixed value DUID1 based on the username and terminal MAC address.

[0082] 3. The authentication server sends the DUID1 and IPv6 binding relationship to the DHCP server;

[0083] 4. The authentication server sends the relationship between the terminal MAC address and DUID1 to DHCP relay devices that support DUID conversion (such as relay and authentication point gateways);

[0084] 5. When the terminal comes online again, the DHCP relay device receives a Discover message containing the relationship between the terminal's MAC address and the virtual DUID. It then modifies the Discover message, changing the DIUD value in the original message to the corresponding DUID1.

[0085] 6. The DHCP server determines whether there is an IPv6 binding relationship with DUID1 based on DUID1. If there is, it assigns the corresponding IPv6 to the terminal.
