Method and device for establishing long connection

Abstract

The objective of the invention is to provide a method and device for establishing long connection. The connection maintaining operation in a service device is disabled to reduce the resource cost of long connection maintaining of the service device to support more concurrent long connection; a long connection request sent by a client device is received, and a long connection with the client device is established based on the long connection request; and a heartbeat bag sent by the client device is received, and heartbeat response information is sent to the client device based on the heartbeat bag to maintain the connection state of the long connection so as to support more concurrent long connection.

Description

technical field [0001] The present application relates to the computer field, and in particular to a technique for establishing a long connection. Background technique [0002] Transmission Control Protocol (Transmission Control Protocol, TCP) is a connection-oriented, reliable, byte stream-based transport layer communication protocol. Long connection is a kind of connection, usually used for frequent operation and point-to-point communication, such as real-time data communication between client device and server device. A long connection only needs to be established once, and after the connection is successful, it will generally last for a long time. Both parties will use the connection to communicate multiple times. Connections cause a waste of resources. [0003] In the prior art, after the client device and the service device initiate the establishment of a persistent connection, the client device and the service device establish a persistent connection to realize data...

AI Technical Summary

Problems solved by technology

[0005] The purpose of this application is to provide a method and device for establishing a long-term connection to solve the problem that in the prior art, the long-term connection with the client device is maintained by the service device, which causes the resource overhead of the service device to be too large and cannot accommodate There are a large number of concurrent long connections. At the same time, because there is no data packet communication for a long time in the long connection, the long connection is in a dead state, resulting in the problem that the long connection cannot be maintained.
