Problems solved by technology

[0007] The "push" mode based on tree topology does not require frequent cache exchange, so data transmission is very efficient, but the maintenance cost of tree topology is high, the resource utilization rate of downstream nodes is lower than that of upstream nodes, and the load of the entire network is unbalanced
The "pull" mode based on the mesh topology is simple and efficient, and is adopted by most mainstream applications at present, but its frequent exchange of cont

Abstract

The invention discloses a P2P streaming media scheduling system and method based on coupling of codes. The system comprises a server and a terminal node, wherein the server comprises a control module and an Raptor coding module, and the control module is used for controlling interactive information; the Raptor coding module is used for coding source files and generating Raptor coding packs, and the Raptor coding packs are transmitted to a network in the transmitting time slot; the terminal code comprises a control module, network coding and decoding modules and an Raptor decoding module, wherein the network coding module is used for performing NC recoding on the received coding packs, then the coding packs are transmitted to neighboring downstream nodes, or decoding is performed when enough coding packs are received, and next the coding packs are transmitted to an Raptor decoder; the Raptor decoding module is used for decoding the Raptor coding packs having been decoded by a network decoder, and original data packets are restored. According to the system and method, Raptor codes and network codes are effectively cascaded, a complex scheduling strategy of the streaming media system is simplified, and the bandwidth availability rate and the system throughput rate are improved.

Description

technical field [0001] The invention relates to the technical field of digital home, in particular to a P2P streaming media scheduling system based on coding coupling. Background technique [0002] In recent years, P2P streaming media technology has profoundly affected people's entertainment life, and mature commercial applications such as PPTV, PPS, UUSee, etc. are widely liked by users. However, the rapid development of wireless interconnection technology and intelligent terminals has put forward higher requirements for P2P streaming media technology, and the dynamics and differences of nodes have seriously restricted the development of P2P streaming media technology. In order to enable P2P streaming media technology to better serve users and provide a better user experience in the new Internet era, we need a more efficient P2P scheduling strategy. Here, network coding technology and digital fountain code technology provide us with the direction of progress. [0003] The...
