Problems solved by technology

[0005] In some scenarios, such as wireless base station equipment, in order to support multi-mode, there will be a need to switch between multiple different modes (2G / 3G / 4G). It is uncertain which single board in the base station needs to be connected to the DHCP server. Therefore, it is impossible to flexibly specify which single board is used as the relay agent according to different scenarios

Embodiment 1

[0032] see figure 1 , this embodiment provides a method for generating a relay agent, the flow of the method is as follows:

[0033] 101: After detecting the connection with the Dynamic Host Configuration Protocol DHCP server, send the broadcast message that the board supports the relay agent;

[0034] 102: Receive a relay agent request sent by a board that needs a relay agent after receiving the broadcast message;

[0035] 103: Confirm whether to accept the relay agent request;

[0036] 104: If the relay agent request is accepted, use this board as a relay agent for the single board requiring a relay agent.

[0037] In this embodiment, by detecting that the single board connected to the DHCP server sends a broadcast message that the board supports the relay agent, and after receiving the relay agent request sent by the single board that needs the relay agent, select whether to accept the relay agent request , if you choose to accept, it will be used as the relay agent of t...

Embodiment 2

[0039] This embodiment provides a method for generating a relay agent, such as figure 2 In the shown interaction diagram, the method for generating a relay agent provided by this embodiment is described by taking a network device including single boards A, B, and C as an example. see image 3 , the method flow is as follows:

[0040] 301: Boards A, B, and C in the network device respectively detect whether their own network ports can be connected to the DHCP server.

[0041] Specifically, since the board connected to the DHCP server inside the network device is unknown, all boards in the network device can detect whether their own network ports can be connected to the DHCP server, wherein the network ports include But not limited to Ethernet port.

[0042] In this embodiment, only board B in the network device is directly connected to the external network as an example, so only board B can successfully detect that it is connected to the DHCP server. Assume that board B su...

Embodiment 3

[0063] see Figure 4 , this embodiment provides a veneer, characterized in that the veneer includes:

[0064] A detection module 401, configured to detect whether a DHCP server is connected to the Dynamic Host Configuration Protocol;

[0065] The broadcast module 402 is used to send a broadcast message that the board supports the relay agent after the detection module 401 detects that it is connected to the DHCP server;

[0066] The first receiving module 403 is configured to receive the relay agent request sent by the single board that needs the relay agent after receiving the broadcast message sent by the broadcast module 402;

[0067] The processing module 404 is configured to confirm whether the relay agent request is accepted, and if so, use the board as the relay agent of the single board that needs the relay agent.

[0068] Further, see Figure 5 , the board also includes:

[0069] The first sending module 405 is configured to send a DHCP request message carrying an...

Abstract

The invention discloses a relay agent generation method, single boards and network equipment, belonging to the communications field. The method comprises: transmitting radio news signifying principal board support for the relay agent after probing that a single board is connected with the dynamic host configuration protocol (DHCP) server; receiving the relay agent request transmitted by a single board needing relay agent after receiving the radio news; judging whether or not to accept the relay agent requestor not; if yes, being used as the relay agent of the single board needing relay agent. The single board comprises a detection module, a broadcasting module, a first receiving module and a processing module; network equipment comprises one or a plurality of single boards. In the invention, the single board probed to be connected with the DHCP server and the single board needing relay agent select each other, thus realizing dynamic generation of the relay agent; the relay agent is generated inside the network equipment and the communication between the single boards is performed inside the network equipment, thus having the effects of intranet and extranet separation and safety assurance.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for generating a relay agent, a single board and network equipment. Background technique [0002] With the development of network technology, a large number of network devices emerge. Since the locations and topological structures of network devices are easy to change, many network devices need to obtain a dynamic IP (Internet Protocol, Internet Protocol) address to access the network. In order to obtain a dynamic IP address, most network devices have a function of obtaining a dynamic IP address assigned by a DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) server. If the network device and the DHCP server are in the same physical network segment, the network device can directly obtain the dynamic IP address assigned by the DHCP server; if the network device and the DHCP server are not in the same physical network segment, a relay a...
