CN-122002648-A - TCP connection release method, device, equipment and medium

Abstract

The present disclosure relates to a method, an apparatus, a device, and a medium for releasing a TCP connection, where when a preset time period is reached, the number information of data packets transmitted by a target TCP connection within a preset time period is obtained, and when the number of data packets transmitted by the target TCP connection within the preset time period is zero, the target TCP connection is released. The TCP connection can be released without four handshakes, so that the release efficiency of the TCP connection is improved, and the system overhead is reduced. And whether the number of data packets transmitted by the target TCP connection in the preset time length is zero or not is judged, so that the invalid TCP connection without data can be accurately identified, and the false release is avoided.
