A dhcp message processing method, dhcp server and gateway device

Abstract

The invention relates to a dynamic host configuration protocol technology, which discloses a DHCP message processing method, a DHCP server and a gateway device, and solves the problem of limited use and lack of versatility in the processing scheme in the traditional technology, allowing the DHCP client to Use the original lease information to continue to use the network to prevent business interruption. The method comprises the following steps: when the IP address of the DHCP server changes, the DHCP address pool information is updated, and the original DHCP address pool information and the original lease list are recorded; the DHCP server detects the online status of the DHCP client in the original lease list, If there is a DHCP client online, create an agent, and the agent will receive and process the DHCP messages of the DHCP clients in the original lease list; if no DHCP client is online, clear the original lease list and the original DHCP address pool information.

Description

technical field [0001] The invention relates to a dynamic host configuration protocol (DHCP) technology, in particular to a DHCP message processing method, a DHCP server and a gateway device. Background technique [0002] With the continuous development of the network, more and more terminals need to be connected to the Internet. When the network scale reaches a certain level, it becomes difficult to manage. Especially in a network where IP addresses are manually assigned, the most common problems are IP address conflicts and IP address management. A solution to such problems is to use the DHCP protocol to dynamically assign IP addresses to clients. [0003] The DHCP protocol works in the client (Client) / server (Server) mode, the DHCP Server is responsible for the allocation and management of IP addresses, and the DHCP Client is the device (such as PC, mobile phone, tablet computer or other devices) that needs to be assigned an IP address. During the DHCP process, the DHCP...
