Aggregation link load sharing method and device

Abstract

The invention discloses are aggregation link load sharing method and device. The method includes: configuring various load sharing algorithms in a network device; starting the network device to test each self-configured load sharing algorithm for a preset duration; sharing ingress port flow to member ports in an aggregation link group by the current load sharing algorithm for testing within the test duration, calculating bandwidth of the member ports in the aggregation link group after testing, and calculating and recording differences between maximum bandwidth and minimum bandwidth of the member ports; and when testing by the load sharing algorithms is complete, selecting the load sharing algorithm corresponding to the minimum difference as the finally used load sharing algorithm. By the use of the method and device, load sharing efficiency of the aggregation links is improved.

Description

technical field [0001] The present invention relates to the technical field of link aggregation, in particular to a method and device for load sharing of aggregation links. Background technique [0002] Link aggregation is a technology often deployed on Ethernet networks. By aggregating multiple physical interfaces into one logical interface, link bandwidth and reliability are increased. figure 1 A schematic diagram of an existing typical link aggregation is given. [0003] The main advantages of using link aggregation are as follows: [0004] Bandwidth increases linearly: theoretically, the bandwidth is the sum of the bandwidths of all links in the aggregated link group; [0005] Increased reliability: the damage of a link will not cause the failure of the entire transmission; [0006] Load sharing: user traffic is divided into various links for transmission; [0007] Dynamic configuration: In the absence of manual configuration, the aggregated link group can be dynamic...

Problems solved by technology

[0012] 1. When it comes to the actual network, the network administrator does not know which load sharing algorithm can share the load more evenly. It needs to be manually configured and verified one by one to find the most even load sharing algorithm. For large-scale networks, there are many aggregated links. The workload is very large; the default load sharing algorithm is often used first, and if packet loss occurs, another load sharing algorithm is used. This method is a remedial measure and cannot prevent problems in the bud

[0013] 2. If the network service changes, the current load sharing algorithm may not be suitable for the changed service, and there is no mechanism to notify the network administrator to modify it
