当前的互联网是基于旧的数据网络概念，其作用主要是建立一个容错的网络基础设施，使稀缺和昂贵的资源，如存储和CPU时间的有效共享。它的主要特点是在客户机-服务器模型下任何一对主机之间的端到端通信原则，这非常适合早期的Internet应用，例如，远程登录（CPU共享）和FTP（存储）。近年来，互联网的主要用途已经发展成为内容生成、共享和检索的载体，这由诸如P2P直播和点播流、用户生成内容（UGC）服务（例如，Youtube、Flickr）和社交网络（例如，Facebook、Google+）。为了适应这种转变，在内容中心网络（CCN）的通用名称下，已经提出了对未来互联网架构的重新设计。在本文中，我们提出了一种新的缓存方案，这样的CCN网络和评估网络缓存性能的这种政策，通过比较它与默认的建议政策，通过模拟。
The current Internet is based on the old concept of data networking whose role was to mainly build a fault-tolerant network infrastructure that enables efficient sharing of scarce and expensive resources such as storage and CPU time. Its main feature is the end-to-end principle of communication between any pair of hosts under the client-server model, which was well suited for early Internet applications, e.g., remote login (CPU sharing) and ftp (storage). In recent years, the main usage of the Internet has evolved to become a vehicle of content generation, sharing and retrieval, demonstrated by such extremely hot applications as P2P live and on-demand streaming, User-Generated Content (UGC) services (e.g., Youtube, Flickr ) and Social Networks (e.g., Facebook, Google+). To match such transformation, a clean-slate redesign of the future Internet architecture has been proposed under the generic name of Content-Centric Networking (CCN). In this paper, we propose a new caching scheme for such CCN networks and evaluate the in-network caching performance of this policy by comparing it with that of the default proposed policy via simulation.
