Method for ensuring stability of large data stream by tcp (Transmission Control Protocol)/udp (User Datagram Protocol) double-mode communication

Abstract

The invention relates to a method for ensuring the stability of a large data stream by tcp / udp dual-mode communication. Upon a client end, the method includes the following steps of: (1) reading out items in the default communication mode in a program configuration file, and connecting with a server in the mode; (2) recording the current communication mode c1, tcp (Transmission Control Protocol) or udp (User Datagram Protocol); (3) counting a packet receiving rate a at a regular interval (N seconds); (4) disconnecting the current connection with the server when the packet receiving rate a is lower than an extent x; (5) recreating data connection with the server, and switching the communication mode; and (6) during the normal communication process, transmitting a heart packet to the server for ensuring the health of a link once the heart time heart-t is expired.

Description

Technical field [0001] The invention relates to a method for ensuring the stability of a big data stream by switching between tcp and udp dual modes. Background technique [0002] With the rapid development of large-bandwidth data exchanges such as audio and video, there is an urgent need to improve the stability of data streams. The usual communication methods are either udp or tcp, which cannot maintain data in certain specific network environments. Continuity, for example, some companies have closed all external udp links internally, so that the software used in udp mode communication has to change the configuration to ensure normal operation, which brings increased network maintenance costs and increased network security risks. [0003] At the same time, there will be some network environments. Usually the router will limit the maximum tcp connection. At this time, the software that uses the tcp connection will be cut off. If the software does not dynamically perceive the netwo...

[0002] With the rapid development of large-bandwidth data exchange such as audio and video, there is an urgent need to improve the stability of data streams. The usual communication methods either use udp or tcp, which cannot maintain data stability in certain network environments. Continuity, for example, some companies have closed all external udp links internally, so that the software used to communicate in udp mode has to change the configuration in order to run normally, resulting in increased network maintenance costs and increased network security risks

[0003] At the same time, there will be some network environments where the maximum amount of tcp connections is usually limited by the router. At this time, the software that originally used tcp connection will be cut off. If the software cannot dynamically sense the network changes at this time, then it will Cause data flow interruption, and even have to be re-used through manual configuration
