Abstract

Embodiments of the invention provide a closing method and apparatus for TCP connection. When a server closes the TCP connection with a client end, the server sends a first connection closing notification message to the client end; after the client end receives the first connection closing notification message, the client end sends a connection closing response message to the server; after the server receives the connection closing response message, the server sends a connection reset message to the client end, and after the server sends the connection reset message, the resource occupied in establishment of the TCP connection is released; and the client end receives the connection reset message, and the resource occupied in establishment of the TCP connection is released. According to the closing method and apparatus for TCP connection provided by the embodiments of the invention, when the TCP connection is closed, the server resource can be released in time, the waiting time of the server is reduced, waste of the server resource is avoided, and the server efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for closing a TCP connection. Background technique [0002] With the rapid development of Internet technology, user clients have an increasing demand for downloading various data from network servers. Massive amounts of information are downloaded every day, and the optimization technology of network resources occupied by downloaded data is becoming more and more important. [0003] At present, almost all the download services on the network use the TCP (Transmission Control Protocol, Transmission Control Protocol) protocol. For the TCP protocol, when a TCP connection is closed, a normal and complete TCP connection closing process includes four steps: steps. see figure 1 , figure 1 It is a flowchart of a method for closing a TCP connection in the prior art. The server sends a FIN / ACK (Finish / Acknowledgment, end / confirmation character) message to the c...
