Data transmission method and device

Abstract

The embodiment of the invention discloses a data transmission method, comprising the steps of using a server to obtain an embedding protocol supported by a client terminal device, appointing a proxy device, and employing the embedding protocol supported by the client terminal device; building an optimized connection connected to the proxy device, receiving a data request transmitted by the proxy device and come from the client terminal device, generating response data based on the embedding protocol and sending the response data to the proxy device via the optimized connection, so that the proxy device employs a hyper text transfer protocol to carry out outer-layer package on the response data and send to the client terminal device. The embodiment of the invention also provides a corresponding server and the proxy device. In the technical scheme of the invention, when a specified proxy deice generate a fault, the server can modify the specified proxy device, an optimized connection having a better transmission efficiency than an HTTP connection is built between the server and the proxy device, so that the pressure of the server can be reduced, especially the pressure of the server caused by concurrent user request under a live scene can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and equipment. Background technique [0002] With the rapid development of computer technology, there is an increasing demand for transmitting audio and video signals through the network, and the application of streaming media technology is also becoming more and more extensive. Especially based on the Hypertext Transfer Protocol (HTTP streaming) technology of the existing Hypertext Transfer Protocol (Hyper Text Transfer Protocol, HTTP), since the existing HTTP technology can be used to construct the server and client, the application of streaming media is more convenient. widely. [0003] However, HTTP is a unicast protocol. When the network (web) server accesses a large amount of data and serves many users, some concurrency problems will arise. In some application scenarios, the server may need to provide services for a large number o...

Problems solved by technology

[0005] However, in live broadcast scenarios, such as watching TV programs, data transmission is required to have no or very little delay, so data such as video cannot be pre-cached, and the proxy cannot use caching to reduce the pressure on the server caused by concurrent user requests
