Problems solved by technology

[0004] Existing load balancing devices are usually scattered and deployed in various server clusters, so they are more complicated to deploy and manage
At the same time, each load balancing device needs to run a load balancing algorithm, and then perform load balancing scheduling for the data packets it receives, so it needs higher processing functions and processing performance, which increases the design complexity and manufacturing cost of the device

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a load balancing system, controller and method. Background technique [0002] The core idea of ​​load balancing is to distribute a large amount of concurrent access or data traffic to the network data link and multiple node devices in the load balancing cluster for separate processing, so as to reduce network congestion and reduce the time for users to wait for service responses. In the current network, load balancing devices are widely deployed and applied, which is an important means to improve network service quality. [0003] In a traditional network architecture, a load balancing device is usually deployed at the entrance of each service processing node server cluster. In each server cluster that supports load balancing, there are multiple servers connected together through the network, and the load balancing device deployed at the front end of the cluster distribut...
