Embodiment Construction

[0035] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0036] The main idea of ​​the present invention is: the access service gateway regularly detects the availability of the active and standby DHCP servers, and if a DHCP server replies, it is considered that the DHCP server is currently available, and the user's DHCP message can be sent to the DHCP server.

[0037] see figure 2 as shown, figure 2 It is a flow chart of the present invention to realize active and standby DHCP servers; this flow chart includes the following steps:

[0038] Step 21: Initially, the access service gateway sets the status of the active and standby DHCP servers as unavailable;

[0039] Step 22: The access service gateway sends an available detection message to the active and standby DHCP servers;

[0040] Step 23: The access service gateway determines the status of each DHCP server according to whe...

Abstract

The invention provides a method for implementing master and standby dynamic host configuration protocol (DHCP) servers. An access service gateway regularly detects the feasibility of the master and standby DHCP servers; and if one DHCP server returns a response, the DHCP server is determined to be feasible at present, and a DHCP message of a user can be sent to the DHCP server. Therefore, when the master DHCP server goes down, a system automatically switches to the standby DHCP server so as to keep the normal operation of user service.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for realizing master and backup of DHCP servers. Background technique [0002] World Interoperability for Microwave Access (Wimax) is a new broadband wireless access technology (Broadband Wireless Access Technology) based on the IEEE 802.16 standard. It is a new air interface standard proposed for the microwave frequency band. The Wimax network model includes the following network entities: mobile user terminal, access service network (Access Service Network, ASN), and connection service network (Connectivity Service Network, CSN). The user terminal includes the application client and the mobile client (Mobile Station, MS); the access service network includes the ASN access gateway (ASN-GW, referred to as AGW), and the base station (BaseStation, BS); the connection service network includes the DHCP (Dynamic Host Configuration Protocol: Dynamic Host Co...
