Method of implementing data transmission or stream media transmission using combination of HTTP and P2P

Abstract

The present invention relates to a method for realizing a data transmission or a streaming media transmission by using the combination of an HTTP and a P2P, a protocol performs a transmission to deblock, a client side adopts the method of the combination of the HTTP protocol and the P2P protocol to transmit data, while the download is performed, the play is performed, the data required to be used at present adopts the HTTP method to transmit or uses the data memorized in the download P2P, the data not to be used temporarily is that the data required subsequently adopts P2P method to transmit. The present invention has the advantages that the play request and the response are quick, the time delay is less, the network flow of a server is saved, a data flow between network regions is saved, the manageability of a P2P node is good, and the data of the P2P node is not completely relied on.

Description

technical field [0001] The invention belongs to the field of network communication transmission technology and the field of streaming media playback, and relates to a data transmission control method based on HTTP transmission protocol and P2P transmission protocol, including HTTP and P2P transmission control algorithm, IP address area priority algorithm and data caching algorithm, especially Use HTTP combined with P2P to realize data transmission or streaming media transmission. Background technique [0002] Streaming media refers to media formats played on the Internet / Intranet in a streaming manner, such as audio, video or multimedia files. One of the key technologies for the realization of streaming media is streaming transmission. Streaming transmission mainly refers to decomposing multimedia programs such as audio, video, and 3D media into data packets in a specific way, and transmitting them in real time from the video server to the user's computer. In the system tha...

Problems solved by technology

[0005] At present, there are some streaming media systems using P2P as the transmission mode on the market, and the streaming media systems using P2P mode also have some inherent shortcomings of P2P: first, before P2P data transmission, it is necessary to first request to the Tracker server (seed file server) to own List other computers for the data files you need, and then request data from other computers according to the list, which causes the startup speed to be relatively slow; secondly, P2P data is divided into data blocks, generally ranging from 64K to 256K, Every time you download a data block, you need to request data from other computers, and the network upload speed of each computer is not equal, and at the same time, the playback user base is unstable (the user may not provide data upload after watching), which will cause the data block not to follow. Obtained sequentially, and may not be obtained in time, which will result in pause or discontinuity of playback, and poor user experience

[0006] Furthermore, during P2P data transmission, it is possible that the computers exchanging the same data file are not in the same network area, which will cause the data transmission speed to drop, and for network operators, it will increase the data flow between different networks, thereby increasing Data traffic settlement cost
