基于宽带城域网的P2P流媒体直播模型与方法
A New Model and Method of P2P Live Streaming System for Telecom Broadband Metropolitan
摘要
Abstract
In order to solve the problem of delayed start-up playing time and poor quality of playing in the current live streaming media system,it proposed a new model and method of P2P live streaming system based on distributed tree topology structure. This model is a distributed P2P streaming media distribution network, which is composed of server group,super node group and common node group. It is solved that start-up playing time is long by using the unbalanced MDC coding scheme and dynamic common node service request strategy. It is also solved that quality of playing is poor by optimizing the basic structure of node buffer and using push and pull scheduling strategy of the combination of the buffer. The experiment shows that this model has the more shorter start-up playing delay and better playing experience.关键词
