Method, device and system for end-to-end data transmission in constrained network

Abstract

The invention discloses a method, equipment and a system for end-to-end transmission of data in a challenged network, which relate to the technical field of communication, can realize communication of P2P data in the challenged network with limiting conditions, and are simple to operate and easy to realize. The method for end-to-end transmission of the data in the challenged network comprises the following steps that: a TCP (Transmission Control Protocol) data transmission channel is built between a first client side and an accessible switchboard server, a session key is acquired and is bound with the data transmission channel, and address information and the session key of the switchboard server are sent to a second client side through reliable network service; the second client side utilizes the address information to build a TCP data transmission channel with the switchboard server, and utilizes the session key to bind with the data transmission channel; and the first client side utilizes the data transmission channel to carry out P2P data transmission with the second client side through the switchboard server. The technical scheme can be flexibly applied to various types of network environments so as to have broader application prospect.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method, equipment and system for end-to-end data transmission in a restricted network. Background technique [0002] The end-to-end (Peer to Peer, P2P) technology is a new technology developed in recent years. It changes the traditional client / server model of network communication, and adopts a distributed idea to share network load. High network bandwidth utilization. Due to the superior performance of P2P technology, it has been widely used in services such as user data sharing, voice and video communications, file transfer, remote desktop connection, and video on demand. [0003] However, there has always been a problem that restricted networks cannot perform P2P connections within the restricted conditions, resulting in the failure of end-to-end data transmission. For example, when the networks where two terminals that need to perform P2P data transmission are loc...

Problems solved by technology

[0003] However, there has always been the problem that the restricted network cannot perform P2P connections within the restricted conditions, resulting in the failure of end-to-end data transmission.

For example, when the network where the two terminals that need to transmit P2P data in the Internet are restricted by a network firewall, the two terminals cannot be accessed by external devices, so that P2P data transmission cannot be established. Appropriate scheme for P2P data transmission in restricted networks with restrictions
