Data transmission method and system

Abstract

The embodiment of the invention discloses a data transmission method. The data transmission method comprises the steps of: obtaining a first channel number and first node information from a node server, wherein the first channel number is used for identifying first target data acquired by a first P2P client side; sending the first channel number to a first XMPP client side; receiving a first dataacquisition request sent by the first XMPP client side, wherein the first data acquisition request is generated after the first XMPP client side sends first invitation information generated based on the first channel number to a second XMPP client side through an XMPP server, and receives reception information corresponding to the first invitation information and fed back by the second XMPP clientside; on the basis of the first data acquisition request, acquiring the first target data; and sending the first target data to a first node. According to the technical scheme in the invention, the P2P and the XMPPP are combined; the advantages of the P2P and the XMPPP are utilized; therefore, the expandability is high; the usable range is wide; and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a data transmission method and system. Background technique [0002] At present, network information systems can be divided into two categories, which are application systems based on C / S architecture (client / server) and P2P (peer to peer, partner to partner) architecture. P2P applications allow hosts to directly communicate with each other through the Internet, and a P2P overlay network (Overlay Network) is formed among many peers, so that various data (such as text files, video files, etc.) can be easily shared between common hosts . It has great prospects in global instant messaging (such as Skype), file sharing (such as BT), distributed computing, and collaborative work. P2P makes communication on the network easier and more direct sharing and interaction and transmission. [0003] XMPP is a protocol based on XML, a subset of the standard general-purpose markup l...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventors have found at least the following problems. In the existing data transmission technology, there is a solution for combining P2P and other methods for data transmission, but there is no solution for combining P2P and XMPP. Now Some technical solutions have poor scalability, which is not conducive to the further expansion of the entire data transmission system. Therefore, a data transmission method and system that can combine the advantages of P2P and has super scalability needs to be developed urgently
