Embodiment Construction

[0020] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0021] The method for improving the load balancing capability of routers among VRRP backup groups according to the present invention will be described below in conjunction with the accompanying drawings.

[0022] In the environment of multiple VRRP backup groups, after a certain device fails, the load sharing of traditional VRRP devices between the backup groups deteriorates. The priority is fixed after configuration, but in actual use, due to the different load shared by each device, the current remaining bandwidth of each device is also different. Therefore, the current remaining bandwidth of the device with high priority may not be the largest, resulting in load Inequalities worsened. Therefore,...

Abstract

The invention discloses an equipment priority realization method and a device in a virtual router redundancy protocol (VRRP) backup group, wherein the method comprises the following steps that: when a preset moment is reached, the current forwarding capability and the current carrying flow rate of each equipment are obtained; and the recorded priority of each equipment in each VRRP backup group is updated respectively according to the recorded priority of each equipment in each VRRP backup group, the recorded rest bandwidth of the equipment and the obtained current forwarding capability and the current carrying flow rate of the equipment. Through the method and the device, the VRRP equipment can realize the balanced sharing of forwarding loads of a network in an environment of a plurality of VRRP backup groups.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for realizing device priority in a virtual router redundancy protocol (VRRP for short) backup group. Background technique [0002] Virtual Router Redundancy Protocol (VRRP for short) is a device redundancy technology, which is used to solve the problem that the hosts in the LAN cannot access the external network after a single point of failure occurs in the statically configured default gateway in the LAN environment. . In VRRP, two or more physical devices (generally devices with routing functions, such as routers) gather together to form a virtual device (or VRRP backup group), and provide consistent virtual IP and virtual MAC to the outside world. address. Hosts in the LAN can access the external network by specifying the virtual IP as the default next hop. In the same VRRP backup group, only one physical device is responsible for forwarding packets bet...
