[0038] Step S11, setting abnormal state configurations for the routers in the router backup group.

[0039] Setting the abnormal state configuration for the router can be realized by the aggregation router, and the aggregation router can also set the normal state configuration for the active and standby routers in the router backup group.

[0040] Since the routers in the router backup group are configured with the IP address of the aggregation router, the routers in the router backup group can send packets to the aggregation router according to the IP address. As shown in Figure 2, under normal circumstances, the bandwidth of the active router A is set to 9.9M through QoS configuration, and the bandwidth of the standby router B is set to 0.1M. The bandwidth of A is set to 0.1M, and the bandwidth of the original backup router B is set to 9.9M.

[0059] Step S21, setting abnormal state configurations for routers in the router backup group, including bandwidth and users in abnormal states.

[0060] Since the routers in the router backup group are configured with the IP address of the aggregation router, the routers in the router backup group can send packets to the aggregation router according to the IP address. As shown in Figure 2, the first router A and the second router B are backup routers for each other. Under normal circumstances, the bandwidth of the first router A is set to 5M through QoS configuration, and several users are set on the first router A. At the same time, set the bandwidth of the second router B to 5M, and set several other users on the second router B. When the first router A is abnormal, set the bandwidth of the first router A to 0.1M through QoS configuration. And set the bandwidth of the second router B to 9.9M, and set the users of the first router A to the second router B.

Abstract

A method for dynamically allocating bandwidth of a router based on VRRP comprises setting an abnormal state configuration for the router in a router backup group; subjecting the router of the router backup group to main-backup switching when one of the router in the router backup group is abnormal, and loading an abnormal state configuration to the router in the router backup group. The invention has the advantages that the bandwidth requested by a user can be utilized sufficiently thereby to protect the investment of the user.

Description

technical field [0001] The present invention relates to VRRP (Virtual Router Redundancy Protocol, Virtual Router Redundancy Protocol), in particular to a method and system for dynamically allocating bandwidth by a router based on VRRP. Background technique [0002] In applications that require high reliability, users sometimes use two routers to connect to the network, and run the VRRP protocol between the two routers. As shown in Figure 1, when one router fails, another router takes over to ensure that the network connection is not interrupted. [0003] VRRP organizes a group of routers in the LAN (including a main router, namely the active router, and several backup routers, namely the backup routers) into a virtual router, which is called a backup group. [0004] This virtual router has its own independent IP address, such as 10.100.10.1 (this IP address can be the same as the interface address of a router in the backup group), and the routers in the backup group also ha...
