Example Embodiment

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0042] The embodiment of the present invention discloses a load balancing method and system applied to a distributed application system. The system of the present invention receives a request sent by a client, first determines whether the client establishes a connection, and selects when the connection is not established. A server with a lighter load establishes a connection with the client. After the client establishes a connection with ...

Abstract

This invention relates to a load balancing method and system applied to a distributed application system. The method comprises the steps of: receiving a request sent by a client; judging whether the client establishes a connection with a server, when no connection is established, selecting a server with lighter load to establishing a connection with the client; when the connection is established between the client and the server, judging whether the load of server is excessive; when the load of server is excessive, releasing the connection of the client with the server and re-selecting other servers with lighter load to establish a connection; and submitting the request to the connected server for execution. The invention avoids that the server can continuously process the request of the client under the condition of excessive load of the server, and ensures balance distribution of the load among the servers, thereby improving the reliability of the load balancing. .

Description

technical field [0001] The present invention relates to the field of information technology, and more specifically relates to a load balancing method and system applied to a distributed application system. Background technique [0002] At present, with the increase of business volume, the rapid growth of access volume and data flow in each core part of the existing network, its processing capacity and calculation intensity also increase accordingly, making it impossible for a single device to bear it. Therefore, the load balancing mechanism came into being. pregnancy. [0003] Load balancing refers to the balanced distribution of loads to multiple computers, network connectors, processors, hardware devices or other resources in a network environment in order to obtain higher resource utilization, improve system throughput, and reduce response time. time to avoid overloading. [0004] An existing load balancing method is to directly select a server with a lighter load when ...
