Embodiment 1

[0047] The multi-server address matching method provided by Embodiment 1 of the present invention, its flow is as follows image 3 As shown, the execution steps are as follows:

[0048] Step S11: the client sends a discovery message to the relay device.

[0049] The client can send a discovery message to the relay device by broadcasting.

[0050] Taking the DHCP client as an example, the DHCP client broadcasts a DHCP Discover broadcast packet to find a DHCP server.

[0051] The discovery message sent by the client may include the network address that the client expects to obtain, such as the IP address used last time; it may also not include the network address and be randomly assigned by the server.

[0052] Taking a data message using the DHCP protocol as an example, the format of the DHCP message (including a discovery message, a discovery response message, a request message, a request response message, etc.) is shown in Table 1 below. The number in indicates the number...

Embodiment 2

[0080] The multi-server address matching method provided by Embodiment 2 of the present invention, its flow is as follows Figure 4 As shown, the execution steps are as follows:

[0081] Step S31: the client sends a discovery message to the relay device.

[0082] The details are the same as step S11, which will not be repeated here.

[0083] Taking the DHCP client as an example, the DHCP client broadcasts a discovery packet. In order to request an IP address from the DHCP server through the relay device.

[0084] Step S32: When the relay device receives the discovery message, it judges whether the address selection field in the received discovery message carries a pre-selected network address.

[0085] If yes, execute step S34, and if no, execute step S33.

[0086] Because the discovery message sent by the client may contain a pre-selected network address that is expected to be obtained by the user. Therefore, before the relay device sends a discovery message to the serve...

Abstract

The invention discloses method, system and trunk equipment for assigning multiple server addresses. The method comprises the following steps of: forwarding received discovery messages sent by a client to servers by the trunk equipment; when the trunk equipment receives the discovery response messages returned by the servers, resolving out carried network addresses from address choice fields of the discovery response messages and judging whether the resolved network addresses conflict with the stored and assigned network addresses or not; if so, returning the conflicting messages to the servers to require the servers to renewedly assign network addresses; and if not, forwarding the discovery response messages to the client, and requiring the servers to assign the network addresses carried in the discovery response messages by the client. The method effectively avoids the assigning conflicts of multiple server network addresses, reduces the time delay in the address assigning process and improves the system performance.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a multi-server address allocation method, system and relay equipment. Background technique [0002] Dynamic Host Configuration Protocol (DHCP) adopts the operating mechanism of client and server, and is a TCP / IP standard that simplifies the configuration and management of host IP addresses. This standard allows DHCP servers to provide IP addresses and other related configuration information to clients. In the network, by enabling the DHCP service, the DHCP client can automatically obtain the IP address and related configuration parameters after each startup, reducing the configuration and management operations of the IP address. In a network with a large number of clients (such as personal computers PC) and divided into multiple subnets, the advantage of the DHCP server is more obvious. [0003] In a large-scale network application environment, multiple centralized DHCP s...
