摘要:
 信息中心网络( Information-Centric Networking,ICN)是未来网络架构中较为重要的一种。它采用信息缓存技术,提供了一种更加适用于今天的网络使用现状(尤其是内容分发与移动)的网络基础设施的服务,要求每个节点都能缓存流经的内容,使得覆盖全网络的缓存成为网络体系结构的一部分。近年来,存储机制成为ICN研究的一项热点,它减轻了服务器、核心路由器、网络链路的负载,降低了传输延时,提高了网络性能。文中主要研究ICN的存储机制(caching),介绍了其特征、分类,探索了其主要研究内容,重点分析比较了几种缓存放置策略和缓存替换算法,最后指出了未来研究方向与面临的挑战。
Abstract:
 The Information-Centric Networking ( ICN) is one of the important approaches of several future network architectures. This approach provides a network infrastructure service that is better suited to today’ s network ( especially in content distribution and mobili-ty) by making use of caching technique. In ICN,each node could cache the content object,which makes the caching become an inherent part of the network architecture. The caching technique in recent years becomes a hot spot in study of ICN,because it declines the load on server,routers and network links,and reduces the transport latency,in the meanwhile improves the network performance. Focus on the caching mechanism in ICN in this paper,and summarize the new features and taxonomies. Then explore its research spot,in particular an-alyzing and evaluating the existing cache decision policies and cache replacement algorithms. Finally,several key issues and challenges in ICN caching are discussed and future directions are pointed out.
