A load balancing method and system

Abstract

The invention discloses a load balancing method and system. The method includes the steps of: a message is received from outside through a link port of each load balancing single machine; each load balancing single machine performs flow classification on the received messaged according to a preset flow classification strategy, and determines a combination of matching rules that the received messages meet; according to a corresponding relation between the preset matching rule combination and each load balancing single machine, each load balancing single machine allocates the received message to the corresponding load balancing single machine to be processed; and each load balancing single machine performs internal load balancing according to the message that needs processing, and sends the message that needs processing to a corresponding outlet port according to a result of internal load balancing. By use of the load balancing method and system provided by the invention, even if homologous and homoclinic load balancing of a large-scale link is performed, while the load balancing is performed, the output messages meet homologous and homoclinic rules, storage space can be reduced, and overall performance of a system can be improved.

Description

technical field [0001] The invention relates to data transmission technology, in particular to a load balancing method and system. Background technique [0002] At present, with the rapid development of network technology, more and more data are transmitted through network technology. When performing the above data transmission, the corresponding server is generally used for transmission. In order to ensure the working efficiency of each server, load balancing equipment will be used during data transmission. The load balancing device will complete the corresponding data transmission according to the preset allocation strategy and each data request received. [0003] During the above data transmission, there is usually a requirement of the same source and same destination, that is, the packets of the same session are sent from the same egress port. [0004] A corresponding data transmission method has been proposed in the prior art. In this data transmission method, it wi...

Problems solved by technology

[0005] However, there are still some problems in the above-mentioned prior art. For example, the existing technical solutions are generally only suitable for homologous and same-destination load balancing when there are only a small number of link accesses. In the case of the same-source and same-destination load balancing of multiple access links (for example, more than 200 link access), it is completely incompetent, so it is difficult to make the output packets conform to the same-source and same-destination rule while performing load balancing
