A method and system for establishing a data connection channel

Abstract

The invention discloses a method and a system for establishing a data connection channel. By adopting the method, a connection based on a UDP protocol is established between a client and an intelligent terminal.The physical connection can be automatically switched seamlessly between the P2P connection channel and the UDP forwarding channel, The UDP protocol is connection-free, data can be sent aslong as you know the peer address, so for the application layer, The channel switching of the technical scheme of the invention is actually the address switching of the destination terminal, and is not the switching of the actual network link, thereby avoiding the problems of data loss and data delay caused by the protocol switching, reducing the running pressure of the server, and further realizing the high-efficient seamless switching of the connection channel without loss.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and system for establishing a data connection channel. Background technique [0002] P2P is point-to-point communication, also known as peer-to-peer Internet technology, which is a new network technology. The traditional network terminal equipment and client data exchange is basically completed through the data forwarding mode of the public network server. The specific schematic diagram is as follows: figure 1 As shown, this mode requires the server to consume a large amount of network bandwidth and also increases the pressure on the server, and the operating cost is relatively high. [0003] In order to better solve the pressure on the server, save network bandwidth and improve user experience, the application of P2P technology provides a good solution. The P2P connection process needs a public network server to assist. After the network terminal d...

Problems solved by technology

[0006] The present invention provides a method and system for establishing a data connection channel, which is used to solve the problem that the switching between the two protocols is logically complicated when switching between two protocols in the prior art, and will also cause certain losses to data transmission. Moreover, TCP needs to establish a long connection with the server, which consumes a lot of server resources, which increases the pressure on the server and relatively high operating costs.
