具有社团感知缓存策略的信息中心网络分析

Information Center Network Analysis with Community Aware Caching Strategy

为了提高信息网络缓存内容在时空上的分布合理性,论文提出了一种具有社团感知缓存策略(SCCNC)的信息中心网络,选择以编码替代移除的缓存替换策略,在保持原先节点缓存空间的前提下,进一步增加缓存内容的多样性并提高缓存的命中率。SCCNC机制对于小的α参数以及用户数比较少的情况将会表现得更加明显。当把原始块缓存到可具有较高社团重要度的节点上时,将会导致此类节点更易被别的节点进行访问。SCCNC表现出了比其他方案更优的跳数减少率。

In order to improve the information network in time and space distribution of rationality,this paper puts forward a kind of community awareness caching strategies(SCCNC)network information center,chooses to encode alternative to remove the cache replacement strategy,on the premise of keep the original node cache space,and further increases the diversity of the cache contents and improves the cache hit ratio.The SCCNC mechanism will be more obvious when the number of users is small and the number of users is small.When the original block is cached on nodes that have higher community importance,it will make such nodes more accessible to other nodes.SCCNC shows a better rate of reduction in the number of jumps than other schemes.
