Multi-path load balancing method based on business perception

Abstract

The invention provides a multipath load balancing method based on service awareness. The method is used for balancing loads according to path weight and aware service traffic. The load balancing method includes the following steps that a network topology structure is determined; routing information and bandwidth information of the network topology structure are collected; according to the collected routing information, multiple paths of all routes are calculated; according to the collected bandwidth information, all link bandwidth information and available bandwidth information of all the paths are acquired so as to calculate weight of all the paths; the calculated multiple paths and the corresponding path weight are configured; load balance is achieved by the aware service through the configured multiple paths and the corresponding weight. The multipath load balancing method based on service awareness follows up the bandwidth of links so that the multiple paths and the corresponding path weight can be calculated, frequent updating of the routes is avoided, when the loads are balanced, bandwidth allocation is performed according to the weight of all the paths, meanwhile traffic is in awareness, and therefore load balancing is performed according to the aware traffic and the weight of the multiple paths.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a multi-path load balancing method based on business perception. Background technique [0002] At present, the users and applications on the Internet are growing rapidly, and the congestion in the network has become a very important problem. The congestion in the network comes from the unbalanced distribution and allocation of network resources and network traffic. Therefore, the traffic load balance meaning becomes more prominent. The interior gateway protocol achieves the load balancing goal through route optimization, adjusts and sets the weight of each link in the network to control the network routing, and achieves the load balancing goal. [0003] However, because the traffic distribution information in the network is not used, the network resources cannot be used effectively, and the link weights are associated with the load status on the current link, which will cause fr...

[0003] However, because the traffic distribution information in the network is not used, the network resources cannot be used effectively. At the same time, link weights and the load status on the current link will cause frequent routing changes, resulting in network instability.
