【摘要】：随着网络流量的急剧增长,现有的IP体系架构难以满足用户不断增长的需求。CCN成为未来网络研究的热点,其最大的特点是网络节点的处处缓存,所以为CCN设计一种高效的缓存机制显得尤为重要。针对CCN中现有的缓存机制存在一些问题,提出了一种基于内容收益的内容流行度和节点重要度PBCS的缓存方案。在请求次数满足收益标准的前提下,进行内容流行度与节点重要度的匹配,得到符合要求的缓存节点。仿真结果表明,该方案提高了内容的节点命中率,缩短了获取内容的平均跳数。
[Abstract]:With the rapid growth of network traffic, the existing IP architecture is difficult to meet the growing needs of users. CCN has become a hot topic in the future network research. The biggest characteristic of CCN is the cache of network nodes everywhere. It is particularly important to design an efficient caching mechanism for CCN. Aiming at some problems in the existing caching mechanism in CCN, this paper proposes a caching scheme based on content revenue based on content popularity and node importance PBCS. On the premise that the number of requests meets the profit criteria, the content popularity and node importance are matched to obtain the cache nodes that meet the requirements. The simulation results show that the scheme improves the hit rate of content nodes and shortens the average hop number of content acquisition.
