一种用于内容中心网络的缓存随机放置策略
Random cache placement strategy for content-centric networking
摘要
Abstract
Content-Centric networking (CCN) is a new network architecture,which has broken the traditional end-to-end communication mode and focuses on contents.In CCN,in-network caching can enhance content delivery on a global scale without requiring a special infrastructure.In this paper we propose a distributed random cache placement strategy,in which caching nodes are selected based on the distance to the content provider.Then the expression for the cache hit ratio is derived as functions of the content request rate,content popularity distribution and cache size in each node.Numerical analysis and simulations show that our strategy can improve the cache hit ratio and reduce average hops to get contents by 5.59%~6.86%.关键词
