一种网状结构的流媒体应用层组播模型

a Mesh-model Overlay Network for Media Streaming Multicast

文中提出了一种网状结构的流媒体应用层组播模型。即在组播流媒体数据应用中,采用一个网状的网络覆盖模型,除了流媒体内容提供者外,任何一个节点都可以是数据的提供者或接受者。通过推理与实验证明,采用这种方式在一定程度上解决了基于树型或者代理型的流媒体应用层组播模型时对节点带宽利用不足以及部署成本较高、系统健壮性较差的缺陷。

This paper provides a mesh-model overlay network to create an application layer multicast (ALM) system for media streaming. The core operation on the model is every simple: every node periodically exchanges available information with a set of partners, and retrieves data from others, or supplies data to partners. The experiments demonstrated: this model is easier to implement, more efficient and robust than tree-model or proxy-model overlay network.
