Embodiment Construction

[0017] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings of the description.

[0018] Such as figure 1 As shown, the gateway server implements the load balancing function for terminal link maintenance through the load balancer, and the terminal links are distributed to the gateway server according to the rules through the load balancer, and the gateway server can dynamically increase and decrease nodes. The load balancer regularly monitors the health status and pressure of the gateway server, and allocates connections by configuring corresponding weights, which includes the following steps:

[0019] 1) Set the weight according to the hardware configuration of each gateway server, and divide the gateway servers into three grades according to the pressure of the maximum number of links that can withstand: Class A (80,000), Class B (160,000), and Class C (200,000) ;

[0020] 2) Maintain the li...

Abstract

The invention relates to a load balance distribution method, in particular to a load balance distribution method based on host pressure. For a traditional load balance technology, some servers are prone to being overloaded during load distribution. The load balance distribution method comprises the following steps that the weight is set according to hardware configuration situations of each gateway server; a load balancer maintains a gateway server list and the weight information of each gateway server; the load balancer determines distribution paths, and updates the current link number of each gateway server; every time the load balancer distributes a link to each gateway server, the current link number plus one is achieved by a counter; when the service of one gateway server is abnormal, the load balancer distributes the links of the abnormal gateway server to other gateway servers; when the load of the corresponding gateway server is larger than a preset threshold value, new links are not distributed to the corresponding gateway server any longer. According to the technical scheme, the situation that system performance is limited due to the fact that some gateway servers are overloaded can be effectively avoided.

Description

technical field [0001] The invention relates to a load balancing distribution method, in particular to a load balancing distribution method for large-scale data collection. Background technique [0002] The reliability of the system depends on the technical architecture of the system. Any single node will become the bottleneck of high availability. It needs to support load balancing design and support linear expansion. Traditional load balancing technologies mostly use random distribution, weight classification, and minimum connection Fixed strategies such as data distribution make it easy for some servers to be overloaded in the load distribution of servers. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, and to provide a load balancing distribution method based on host pressure, so as to achieve the purpose of load balancing. For th...
