摘要:
 为了克服现有Internet存在的众所周知的缺点，未来网络成为研究热点，而以内容为中心的网络( CCN)在众多方案中被认为是最有前途的方案之一。 CCN网络采用了分布式的内容缓存机制，允许节点对传输的内容进行缓存。而缓存放置策略是研究的热点。文中在对几种常见的缓存决策方案进行分析的基础上，分析存在的问题，重点研究了一种动态缓存决策方案，根据内容的流行度规律和用户的潜在需求，在必要的节点上选择性地进行缓存。然后在ccnSim上进行仿真对比，实验结果表明，缓存效率明显高于基本的缓存策略。
Abstract:
 In order to overcome the well known deficiencies of the current Internet,the future network is becoming the research hotsopts, and great expectations are held on the Content-Centric Network ( CCN) . A distributed cache strategy which allows the network node to store the content is used in CCN. The cache placement of CCN is a popular issue now. With the analysis of some common cache place-ment strategies,propose a dynamic cache placement strategy based on the popularity of the content and potential demands. Content will be cached on some nodes. Then,simulation experiments are conducted on ccnSim. The experimental results show the cache efficiency will be obviously improved.
