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 hig

Embodiment Construction

[0041] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] The load balancing mentioned in this application mainly refers to: a large amount of concurrent access or data traffic is distributed to multiple node devices for separate processing, reducing the time for users to wait for a response. This is mainly for network applications such as Web servers, FTP servers, and enterprise key application servers. .

[0043] In this application, when the client needs to access an application service, it first requests access to the dispatch service. The dispatch service will dynamically adjust the distribution strategy according to the load of the backend server (such as the actual number of people online, etc.). The server that is relatively idle at the back end ...

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...
