随着内容传播需求的不断增长，以内容为中心的网络（CCN）被认为是未来互联网的一种有前途的架构。为了应对CCN缓存中的挑战，我们开发了一个在线缓存方案（命名为RBC-CC），利用路由介数中心（RBC）和“预取”的概念，旨在显着减少昂贵的ISP间的流量，大大减少内容访问跳数。仿真结果表明，提出的缓存方案可以显着优于流行的缓存方法在节省率的ISP之间的流量。此外，RBC-CC在减少平均访问跳数方面表现良好，并且引起最少的缓存回收。此外，我们提出了一个彻底的分析访问模式，缓存大小，内容流行度和人口的影响上的缓存性能。结果表明，该方案具有良好的稳定性和可扩展性，同时具有较好的有效性。
With the increasing demand of content dissemination, Content-Centric Networking (CCN) has been proposed as a promising architecture for future Internet. In response to the challenges in CCN caching, we develop an online caching scheme (named RBC-CC) exploiting the concept of Routing Betweenness Centrality (RBC) and “prefetching”, aiming at significantly reducing costly inter-ISP traffic and largely reducing content access hops. Simulation results demonstrate that the proposed caching scheme can significantly outperform the popular caching approaches in terms of the saving rate of inter-ISP traffic. Besides, RBC-CC performs well in reducing the average access hops and incurs the least cache evictions. Further, we present a thorough analysis regarding the impact of access pattern, cache size, content popularity and population on the caching performance. We then come to the conclusion that our scheme is featured with good stability and scalability as well as its effectiveness.
