Embodiment Construction

[0021] Examples will be described in detail.

[0022] A method for realizing TCP connection backup, comprising the following steps:

[0023] Step 1: Enable the protocol function, enable the global protocol switch through the command line or network management, and then enable the corresponding protocol switch on the specific port;

[0024] Step 2: Create TCP SOCKET communication on the main control panel, call the network interface function of the kernel to create, and create different types of SOCKETs according to different protocols, among which the LDP protocol creates stream sockets;

[0025] Step 3: According to the standard definition of the specific protocol, the APP program running on the main control panel organizes the corresponding standard format message, calls the network communication packet sending interface function of the kernel, and sends the protocol message. The analog switch of the control system is sent to the peer device;

[0026] Step 4: The peer devi...

Abstract

A method for implementing TCP connection backup provided by the present invention is simple in implementation and convenient in maintenance, without modifying the kernel code, and modifying the TCP connection on the application program to realize TCP backup by synchronizing the serial number, and solving the problem of master / backup in a dual-master control system. The problem of service interruption caused by the interruption of the TCP connection caused by the switchover of the master control panel.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for realizing TCP connection backup. Background technique [0002] A dual master control system means that there are two master control panels working together in one system, the active master control panel and the backup master control panel. When the main control panel fails, the standby main control panel takes over all the work immediately, and the docking equipment connected to the system does not perceive the switchover of the main control panel and the backup system. The dual master control system is widely used in the networks of major operators, which can improve the reliability of the network, reduce the annual failure rate and the error rate. [0003] TCP is a connection-oriented, reliable, byte stream-based transport layer communication protocol. Many protocols running in the dual master control system, such as BGP (Border Gateway Protocol...
