Fault tolerance system and method of server

Abstract

The invention discloses a fault tolerance system and method of a server. The system comprises a server pool, a client and a pooling device, wherein the server pool comprises a plurality of servers; the client is used for accessing the server pool; the pooling device is used for managing the server pool composed of the plurality of the servers and carrying out real-time monitoring and collection on operation states of each server; if one server breaks down, the faulted server is immediately removed from the server pool, so as to assure that the servers in the server pool are normally operated; if the connection between parts of the clients and the faulted server is discontinuous due to the fault of the server, parts of the clients are redistributed by the pooling device and the next server operated normally is got; and in the fault tolerance system, the discontinuous connection and service can be smoothly taken over by the new server through a state sharing mechanism. According to the fault tolerance system and method of the server, provided by the invention, the fault tolerance performance of the server can be improved and the normal operation of the system is assured.

Description

technical field [0001] The invention belongs to the technical field of computers and networks, and relates to a fault-tolerant system, in particular to a server fault-tolerant system; meanwhile, the invention also relates to a server fault-tolerant method. Background technique [0002] Services based on Internet technology are increasingly widely used and promoted in various industries. For some network application services that have high requirements for high reliability, a short interruption will bring huge economic and economic benefits to service providers / operators. The loss of reputation, the importance of server fault tolerance is becoming more and more prominent. [0003] In a typical server-client mode, the server determines its location by the DNS domain name, and the client application system must use the DNS service to resolve its domain name before accessing the server, so as to obtain the server's IP address. After the connection between the client and the ser...

AI Technical Summary

Problems solved by technology

[0010] 1. The server list is static and must be specified by the user;

[0011] 2. The selection of alternative servers is quite blind. It cannot guarantee whether the selected server is normal and effective, nor can it be flexibly selected due to the load of the server;

[0012] 3. The takeover is realized through the application program, which lacks transparency;

[0014] 5. In order to meet the guarantee of reliability, the amount of application program development is relatively large
