内容中心网络中基于内容流行度和节点属性的协作缓存策略
A Cooperative Caching Strategy Based on Content Popularity and Node Attributes in CCN
摘要
Abstract
Built-in network cache is an important feature in Content-Centric Networking (CCN).But existing caching strategies make the content distribution uneven,and there is a great room for the cache efficiency to improve.To make the cached contents more reasonable in tempo ral and spatial distribution,this paper proposes a collaborative caching strategy based on content popularity and node attributes(CPA).It can choose the cache content and cache location through the real-time popularity of content and multi-node attribute,reduce network redundancy and con tent replacement,and realize more uniform content distribution.The simulation results show that the proposed cache strategy can effectively improve cache hit rate and reduce network load and overall cache replacement quantity compared with other typical caching strategies.关键词
