Method and computer system for maintaining transmission control protocol connection

Abstract

The invention provides a method for keeping transmission control protocol connection, and a computer system. The method is applicable to the computer system having a network card and a processor, wherein the processor executes an operating system. The method comprises the steps of: firstly, establishing a first transmission control protocol connection with a far-end server by using the network card; then, receiving a wake-up packet transmitted by the far-end server through the first transmission control protocol connection so as to wake up the operating system when the operating enters a power saving mode; and resetting retransmission time of transmitting the wake-up packet by the far-end server when the operating system returns to a normal operating mode. The method and the computer system can avoid connection interruption caused by too long retransmission time of transmitting the wake-up packet by the far-end server, and further ensures that the far-end server can wake up the computer system.

Description

technical field [0001] The present invention relates to a method and device for maintaining network connection, and in particular to a method and computer system for maintaining transmission control protocol connection. Background technique [0002] In recent years, with the rapid development of computer technology, remote control technology has become more and more common. Users can remotely operate the computer system through the network anytime and anywhere. For example, general users can use remote control to control the computer system in the office at home to obtain required data or perform remote operations. System administrators can also use remote control to obtain information such as hardware status, system events, and log records of the computer system from the remote end, so as to grasp the status of the computer system at any time without being limited by time and space. [0003] In today's remote control technology, the remote computer system usually has a ne...

Problems solved by technology

The above situation occurs repeatedly and after five retransmissions, the TCP connection will be interrupted. As a result, the remote server will no longer be able to send wake-up packets through the TCP connection, and the user will not be able to wake up via the network. computer system

[0008] It can be seen from the above that although the retransmission mechanism of the above transmission control protocol can achieve reliable connection, if this architecture is applied to remote wake-up, the connection may be interrupted and become unreliable
