Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method and system for releasing TCP connection resources in view of the deficiencies in the prior art, so as to solve the problem that a large amount of resources are occupied for a period of time in the existing method for releasing TCP connection resources. Can not be used effectively, resulting in the problem that the resource usage of the server system is too high

Abstract

The invention discloses a method and a system for releasing TCP (Transmission Control Protocol) connection resources. The method comprises the steps that after a TCP connected is established between a terminal and a server side, the terminal sends a heartbeat packet to the server side at a periodic interval; if the server side does not receive the heartbeat packet sent by the terminal within a first predetermined time, a detection message is sent to the terminal by the server side; and when the server side does not receive a response message, the server side releases the TCP resources occupied by the terminal, wherein the response message is the response message of the detection messages. In the method, the server side can close the connection without waiting for two or three times of heartbeat timeout, so as to achieve the purpose of releasing the useless connection resources of the server side as soon as possible. Meanwhile, the failure probability of reconnection with the server after the terminal is restarted when being off the Internet and in power failures is reduced, the login speed of the terminal is increased, and the convenience is brought to the use of the user.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and system for releasing TCP connection resources. Background technique [0002] In the Internet field, the TCP (Transfer Control Protocol, Transmission Control Protocol) protocol is widely used, and most C / S server models use TCP connections for reliable communication. Even if the Web application adopts the Http protocol, it cannot be separated from the TCP protocol, because the Http protocol is an application layer protocol, and its underlying implementation still depends on the TCP protocol. The SOCKET connection at both ends of the TCP communication is uniquely determined by a quaternion, namely {terminal IP, terminal port, server IP, server listening port}. The server, usually its IP and listening port are unchanged during the service process, and the IP and port of different terminals are different. As a server, it needs to provide services to a large numb...
