Several customer terminals interdynamic load equalizing method and its system

Abstract

The present invention discloses a multiple customer terminals interactive load balacing method and its system. It is implemented by using several customer terminals, a process front-end and several logic operation servers and their connection, in which the system loads can be distributed on several logic operation servers, according to the load condition the quantity of servers can be increased or reduce,d and the state information of every logic operation server is stored in the process front-end, and the curtomer can directly create connection with correspondent logic operation server according to the indication of process front-end, and the process front-end can be connected with every logic operation server by means of local area network of interconnection network. It can implement load balance, and its logic operation servers can be separately distributed so as to can fully utilize bandwidth of network.

Description

technical field [0001] The present invention relates to a load balancing method and its system. The method and system are used to respond to the requests of a large number of clients and use the distributed method to perform more complex logic operations, and the logic operations can be increased or decreased according to the load conditions. The server does not affect the response to the client request, and is especially suitable for network applications with a large number of clients and a large amount of calculation, such as online games, digital positioning, and digital maps. Background technique [0002] The rapid growth of the Internet has led to a rapid increase in the number of visitors faced by the web server. The web server needs to be able to provide a large number of concurrent access services. The performance of a single server is limited. Generally speaking, a PC server can provide The processing capacity of concurrent visits is about 1000,...

Problems solved by technology

[0004] One is load balancing based on specific server software, using the "redirection" function supported by the network protocol. When the server thinks that its load is heavy, it sends back a redirection command to make the browser go to other servers in the server cluster to get a response. This method is not easy to achieve load balancing, and it is easy for multiple servers to repeatedly send redirection commands to cause an infinite loop;

[0005] The second is load balancing based on the domain name server (DNS), which is realized through random name resolution in the DNS service, that is, in the DNS server, the same name is configured for multiple different addresses, and the client that finally queries this name will be in the DNS server. One of the addresses is obtained during resolution, and different clients may obtain different addresses to access different servers to achieve the purpose of load balancing. The advantage of this method is that it is simple and easy, and the server can be located anywhere on the Internet , but in order to ensure that DNS data is updated in a timely manner, it is generally necessary to set the DNS refresh time to be relatively small, resulting in a large amount of additional network traffic, and changing the DNS data will not take effect immediately. At the same time, the DNS load balancing method cannot Knowing the differences between servers, it is impossible to allocate more requests to servers with better performance, and it is also impossible to understand the current status of servers, and there may even be occasional cases where client requests are
