Embodiment Construction

[0028] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0029]The embodiment of the present invention is applied to a VRRP backup group including multiple routers, wherein the multiple routers include at least a Master router and a Backup router, and other redundant routers are all Backup routers. During the election of the master router, all routers in the VRRP backup group have their priorities set. According to the priority order, the router with the highest priority in the VRRP backu...

Abstract

The invention provides a VRRP load balancing method, a VRRP load balancing device and a router. The VRRP load balancing method is applied to a VRRP backup group comprising multiple routers, and the multiple routers at least include a master router and backup routers. The method comprises the following steps: the master router receives an ARP address resolution protocol request sent by a terminal; and the master router sends the virtual MAC media access control address of the router with minimum total traffic in the VRRP backup group to the terminal according to the latest collating sequence of total traffic of the routers in the VRRP backup group. By implementing the embodiments of the invention, non-uniformity of forwarding traffic of the routers in the VRRP backup group for the existing VRRP load balancing mode is reduced, the forwarding pressure on the router with heavy traffic is alleviated, and traffic load balancing of the routers in the VRRP backup group is realized.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a VRRP load balancing method, device and router. Background technique [0002] Virtual Router Redundancy Protocol (VRRP) is an optional protocol that dynamically assigns the responsibility of a virtual router to one of the VRRP routers on the LAN. The VRRP router that controls the IP addresses of the virtual routers is called the master router, and it is responsible for forwarding packets to these virtual IP addresses. This election process provides a dynamic failover mechanism should the primary router become unavailable, allowing the virtual router's IP address to serve as the default first-hop router for end hosts. [0003] In VRRP standard protocol mode, only the master router can forward packets, and the backup router is in the listening state and cannot forward packets. Although creating multiple backup groups can realize load sharing between multiple router...
