CCN基于内容的缓存策略

Content-based Caching Strategy of CCN

内容中心网络(Content Centric Networking,CCN)以内容为中心进行数据通讯,改变了当前互联网host-host通讯模型,并且具有网内缓存功能。为了解决网内数据协同缓存的难题,借鉴通讯模式的改革,建议以内容为中心缓存数据,提出以内容和缓存为中心的网络(Content&Caching Centric Networking,CCCN)概念。经过大量理论分析和仿真实验,结果表明,在数据缓存和内容转发上CCCN是非常高效和可行的。

The Content Centric Networking （CCN） can implement content centric data communication,which uses content’ s name but IP address for data transmission,changes the current Internet’ s host-host communication paradigm and has in-network cac-hing function.In order to implement in-network data coordinated caching,the content centric caching method is put forward based on revolution of communication mode,and the conception of Content ＆ Caching Centric Network （ CCCN） is proposed. Several simulation experiments are done,and the results show that CCCN is effective and feasible in data caching and content forwarding.
