Load balancing method and system of application services

Abstract

The invention provides a load balancing method and system and of application services, which are used for solving the load balancing problem in the existing network service. The method comprises the following steps of: acquiring the current load information of a rear-end server continuously, wherein the current load information comprises application program operational data of the rear-end server, or comprises the application program operational data of the rear-end server and performance data; in each acquisition period, recalculating the weight of the rear-end server according to the current load information; and adjusting the distribution of the rear-end server according to the weight of each calculation, and selecting the rear-end server to route an access request of a client side. Compared with the traditional load balancing method of the application service, the load balancing method has the advantage that reasonable distribution of traffic is realized among multiple network equipment which can finish the same functions, so that the condition that one equipment is too busy, other equipment can not perform the functions fully is avoided.

Description

technical field [0001] The present application relates to network technology, in particular to a load balancing method and system for application services. Background technique [0002] Load balancing (also known as load balancing), the English name is Load Balance, which means to balance the load (work tasks) and distribute them to multiple operating units for execution, such as Web servers, FTP servers, enterprise key application servers and Other mission-critical servers, etc., so as to complete work tasks together. [0003] Usually, load balancing is divided according to different layers of the network (seven layers of the network). Among them, the load balancing of the second layer refers to the use of multiple physical links as a single aggregated logical link. This is the link aggregation (Trunking) technology. It is not an independent device, but a network device such as a switch. common techniques. Modern load balancing technology usually operates on the fourth o...

Problems solved by technology

[0005] At present, in many network services, with the increase of users and business volume, the rapid growth of access volume and data flow of each core part of the existing network, its processing capacity and calculation intensity also increase accordingly, making a single server device fundamentally unable to bear

In this case, if you throw away the existing equipment and do a lot of hardware upgrades, it will cause a waste of existing resources, and if you face the next increase in business volume, this will lead to another high cost of hardware upgrades. Cost investment, even the equipment with excellent performance cannot meet the needs of the current business volume growth

[0006] Based on this, the problem that needs to be solved at present is: to provide a load balancing method suitable for network services, which can realize the reasonable distribution of business volume among multiple network devices that perform the same function, so as not to cause one device to be too busy , a situation where other devices fail to perform to their full potential
