Problems solved by technology

The value of the VRRP protocol process itself is already very low, and the protocol implementation process is complicated. Only using the VRRP protocol technology can no longer meet the backup networking requirements of the current carrier-grade AC equipment.

Embodiment Construction

[0033] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] To enable those skilled in the art to better understand the embodiments of the present invention, the basic principles of the current VRRP protocol are briefly described below.

[0035] At present, AC equipment in a WLAN network usually deploys one main equipment, one backup equipment and two equipment, which are connected to the core router or BRAS (Broadband Remote Access Server). The main equipment AC is connected to it. The core router and the BRAS device of the peer device need to present an IP address. The router or BRAS device always routes WLAN user messages to the main device AC where the IP address is located. The main device AC can use the VRRP protocol to present a virtual The IP address needs to impleme...

Abstract

The invention provides a method and device for sharing an internet protocol (IP) address by a host device and a standby device. The method comprises appointing a floating IP address, setting relevance between the floating IP address and the host device and enabling the floating IP address to be not related to the standby device; floating the floating IP address to a new host device when the original standby device is switched into the new host device, and removing the relevance between the floating IP address and the original host device. The method and device does not need single design of a decision-making process of the host device, does not need a special port connection line, can be bonded with the host state of the device, reduces software complexity and meets various networking requirements.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for sharing an IP address between a master device and a backup device, and a device for sharing an IP address between the master device and the backup device. Background technique [0002] At present, in WLAN (Wireless Local Area Networks, wireless local area networks), operators have higher and higher requirements for the reliability of WLAN access equipment, requiring carrier-class reliability, AC (Access Controller, (wireless) access controller ) As an access control device, it is usually located in the backbone transmission layer of the WLAN, and manages thousands of AP (Access Point, (wireless) access point) devices. It is usually required to deploy two AC devices, one active and one standby, to enhance reliability. The main device AC needs to present the same IP address to the outside, so that the uplink and downlink devices connected to it can route ...
