Embodiment Construction

[0040] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] The present invention provides a management method based on a dynamic host configuration protocol address pool, referring to figure 1 , in an embodiment, the management method based on the dynamic host configuration protocol address pool includes:

[0042] Step S101, when receiving the request information from the client to obtain configuration information, the relay server broadcasts an address pool request message to each interface;

[0043] In this embodiment, the configuration information includes IP address, DNS address, gateway address, etc., and the whole text of the present invention will be described as an example of assigning IP address information to a client.

[0044] In this embodiment, before processing the DHCP message, the relay server will try to obtain the corresponding address pool from the ...

Abstract

The invention discloses a management method based on a dynamic host configuration protocol address pool, which is applied to a relay server. The management method based on a dynamic host configuration protocol address pool includes the following steps: when receiving a request from a client to acquire configuration information information, the relay server broadcasts the address pool request message to each interface; receives the address pool response message sent by the address pool controller according to the received address pool request message, and obtains the address pool response message in the address pool response message address pool; when it is confirmed that the address pool is a legitimate address pool, use the address pool as the address pool for allocating configuration information for the client. The invention also discloses a relay server. The invention can simplify the work of configuring and managing the DHCP server, reduce the network burden and improve the network performance.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a management method and a relay server based on a dynamic host configuration protocol address pool. Background technique [0002] Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP) is a LAN network protocol, which uses UDP protocol to work, and is mainly used to automatically assign IP addresses to internal networks or network service providers, or to users or internal network administrators as A protocol for central management of all computers. In the TCP / IP network, before exchanging information between hosts, it is necessary to configure information on the host (such as ip address, dns address, gateway address, etc.). The DHCP protocol can dynamically allocate configuration information for hosts in a LAN, and is also a commonly used configuration method in a LAN. [0003] At present, a single LAN can no longer meet the network requirements...
