基于喷泉码的应用层组播
首发时间:2010-11-26
摘要:随着各种具有一对多、多对多通信特点的应用的出现,组播技术已经成为互联网研究中的一个重要方向。应用层组播的模型有效的解决了 IP层组播方案存在的部署困难、扩展性差等问题,然而应用层组播本身也存在着稳定性和可靠性上的缺点。喷泉码是一类码率不受限的纠删码,本文提出将喷泉码思想融合于应用层组播,选取一种应用层组播方案NICE协议进行研究,并且在P2P仿真平台OverSim上进行仿真,实现大规模数据组播的可靠传输。

Application Layer Multicast Based on Fountain Codes
Abstract:With the emergence of one to many, many to many applications, multicast technology has become an important direction of research. Application layer multicast model solve the problems of IP multicast effectively, such as deployment difficulty, and poor scalability. But application layer multicast itself has shortcomings of stability and reliability. Fountain codes are rateless erasure filling codes, this paper proposed application layer multicast based on fountain codes method, and select NICE protocol as research target, and finish the simulation on P2P simulation platform OverSim, achieving the aim of reliable transmission of large-scale multicast.
Keywords: Application Layer Multicast Fountain Code NICE protocol
