Problems solved by technology

[0003] But the existing technology detects the status of the link. When a member link of a link aggregation group fails suddenly, the member is directly removed from the member group. In this way, the data traffic on the failed link will be reduced Will go out from several other working member links
However, removing a member from an aggregation group is not instantaneous. It is necessary to update the link aggregation group (LAG group) table and the link aggregation group member (LAG Group member) table. The outflow of the faulty link leads to being dropped
And due to the reduction in the number of members, a single faulty link will affect the flow of the entire group and must be re-exported. In the end, the member cannot be automatically added after being removed from the group table. After the fault is repaired, the entire link bandwidth becomes smaller

Embodiment Construction

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0037] A method for realizing load balancing disclosed by the present invention, combining figure 1 and figure 2 As shown, the method includes: S1, performing hash routing on the message for the first time to obtain the exit of the first member, and if the link of the exit of the first member is faulty, enter step S2;

[0038] The specific process includes: S11, perform a hash operation according to the field of the message, and calculate a first hash value; S12, obtain the number of members from the link aggregation group table; S13, combine the first hash value and Calculate the number of members to obtain a member index value for indexing the member entry of the link aggregation group table; S14, use the member index value to index the first link aggregation group table from the ...

Abstract

The invention discloses a method and a device for realizing load balancing. The method comprises the following steps: performing hash routing on a message for the first time to obtain a first member outlet, performing hash routing on the message for the second time through a backup group table if a link of the first member outlet is faulty, selecting other backup second member outlets except the first member outlet, and sending out the message from the second member outlet. According to the invention, load balancing is realized, the phenomena of message loss and packet loss are avoided, and the total bandwidth is kept unchanged.

Description

technical field [0001] The invention relates to the technical field of load balancing, in particular to a method and device for realizing load balancing. Background technique [0002] As the network scale continues to expand, users have higher and higher requirements for the bandwidth and reliability of backbone links. In the traditional technology, it is common to replace a high-speed interface board or a device supporting a high-speed interface board to increase bandwidth, but this solution requires high costs and is not flexible enough. Link aggregation technology can increase link bandwidth by bundling multiple physical interfaces into one logical interface without hardware upgrade. While achieving the purpose of increasing bandwidth, link aggregation adopts the mechanism of backup link, which can effectively improve the reliability of links between devices. [0003] However, the prior art detects the state of the link. When a member link of a link aggregation group fa...
