【摘要】 为了使以信息为中心的网络缓存内容在空间和时间上分布更合理,提出一种社团感知的缓存策略(SCCNC);以社团为单位,社团重要度高的节点缓存原始块,其他节点缓存编码块,在不增加缓存空间的条件下,提高缓存命中率和缓存多样性。研究结果表明:SCCNC策略与其他3种策略相比,能更好地提升包括缓存命中率和传输流量等缓存性能。更多还原

【Abstract】 In order to make content cached more reasonable in temporal and spatial distribution in information-centric networking(ICN), a social community-aware caching strategy(SCCNC) was proposed. For each community, original blocks were cached by nodes with more importance to community, and coded blocks were cached by other nodes. Thus, cache diversity and cache hit rate were enhanced without increasing cache capacity. The results show that the proposed scheme achieves better cache performance than other three schemes in terms of cache hit rate and traffic etc.更多还原
