Load balancing method, apparatus and system thereof

Abstract

The invention discloses a load balancing method, an apparatus and a system thereof. The method comprises the following steps of acquiring attribute information of a server and system resource usage condition information, wherein the attribute information includes load balancing group information and an external service IP address, or the attribute information includes the load balancing group information, the external service IP address and external service port information; and the system resource usage condition information includes CPU usage condition information, memory usage condition information, IO condition information, software interruption condition information and network card bandwidth condition information; according to the attribute information, updating a number of servers corresponding to a load balancing group; and according to the system resource usage condition information and the updated load balancing group, updating a load balancing group strategy. In the invention, static configuration of load balancing configuration can be converted, and a rear-end real server actively triggers so that the configuration of the load balancing group is converted into active configuration from passive configuration.

Description

technical field [0001] The present application relates to the technical field of LB (Load Balance, load balancing), and in particular to a load balancing method, device and system. Background technique [0002] Load balancing is to distribute work tasks to multiple operating units for execution, so as to jointly complete work tasks. Operating units, such as Web servers, FTP servers, enterprise-critical application servers, and other mission-critical servers. This technology is built on the existing network structure, which provides a cheap, effective and transparent method to expand the bandwidth of network devices and servers, increase throughput, strengthen network data processing capabilities, and improve network flexibility and availability. [0003] Typical application scenarios of load balancing devices are as follows: figure 1 As shown, its composition is: load balancing device LB Device, which is responsible for distributing various service requests to multiple ser...
