Problems solved by technology

However, for the same video content, usually there will be a large number of user terminals requesting live broadcast. In this way, using the end-to-end packet transmission mode, it is necessary to establish a TCP connection between the HTTP streaming server and each user terminal for the request of each user terminal. , and transmit the packets of the same video content to different user terminals respectively, causing a large number of packets with duplicate content to spread in the operator network, occupying unnecessary bandwidth resources

Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention.

[0038] The message transmission method, device and system provided by the embodiments of the present invention can be applied to, for example, figure 1 Shown is the live video recording system. The live recorded video files are divided into several HTTP files based on Hyper Text Transfer Protocol (Hyper Text Transfer Protocol, HTTP), and these HTTP files are uploaded to the HTTP server, and the HTTP server transmits the HTTP files to the user terminal through the operator network.

[0039] figure 1 In the shown live video recording system, in the process of transmitting HTTP files to user terminals, there are usually a large number of HTTP packets with duplicate content transmitted in the operator's network. In the embodiment of the present invention, in order to avoid such as figure 1 In t...

Abstract

The invention discloses a message transmission method and system and a device. A software defined network SDN controller receives resource request messages sent by user terminals; the SDN controller sends the resource request messages to a server in a proxy mode; a network side router receives messages sent by the server, sends information head messages needing to be transmitted to the SDN controller and sends data body messages needing to be transmitted to each user side router in a preset user side router list; the user side routers modify TCP serial numbers and TCP acknowledgement serial numbers contained in transmission control protocol TCP message headers of the data body messages, generate new data body messages which are sent to the user terminals and send the new data body messages to each user side router in the preset user side router list. Through application of the method, the system and the device, an occupation rate of repeated message transmission for an operator network can be reduced.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message transmission method, device and system. Background technique [0002] With the development of Internet technology, live video services are widely used. [0003] The implementation of the current live video service mainly adopts the following process: the video is divided into several HTTP files based on the Hyper Text Transfer Protocol (Hyper Text Transfer Protocol, HTTP), and these HTTP files are uploaded to the HTTP streaming server cluster. When the user terminal requests a live video, it sends an HTTP request to the HTTP streaming server. After the HTTP streaming server receives the HTTP request sent by the user terminal, it establishes a TCP link with the user terminal based on Transmission Control Protocol (TCP). And use the end-to-end mode to transmit the message to the user terminal through the operator network. However, for the same video conte...
