Load balancing system, controller and method

负载均衡系统、控制器和方法

Abstract

本发明公开了一种负载均衡系统、控制器和方法,涉及云计算技术领域。该系统包括:集中部署的负载均衡控制器,从负载均衡器获得全网中的负载均衡集群的拓扑信息和数据流量信息;根据负载均衡策略为各个负载均衡器生成数据流的转发表项,将转发表项通过统一的控制接口发送给分散部署的各个负载均衡器;负载均衡器根据转发表项将数据流分发给后台的服务器。该系统、控制器和方法,以集中化的方式对网络中分散部署的负载均衡器进行控制,将传统的分散在各个负载均衡设备中的负载均衡逻辑统一纳入到集中的负载均衡控制器中,避免了传统负载均衡难以统一管理的问题,有助于降低管理难度,并且为从全局角度改进网络的负载均衡效果提供了很好地支持。
The invention discloses a load balancing system, controller and method, and relates to the technical field of cloud computing. The system comprises the concentrated load balancing controller and load balancers, wherein the load balancing controller obtains topology information and data flow information of a load balancing cluster in the whole network, generates forwarding items for the load balancers according to a load balancing strategy, and sends the forwarding items to the scattered load balancers via a unified control interface; and the load balancers distributes data flows of the forwarding items to a background server. The load balancers scattered in the network are controlled in a centralized manner, and load balancing logics scattered in load balancing devices traditionally are brought into the concentrated load balancing controller in the unified manner, the problem that traditional load balancing is hard to manage in the unified manner is solved, the management difficulty is reduced, and the load balancing effect of the network is improved globally.
