ICN中基于节点权重的缓存大小分配方案研究
Research on cache size allocation scheme based on node weight in information-centric networking
摘要
Abstract
In order to allocate cache size of each router reasonably,this paper defined a new metric named node weight which considered several metrics (e.g.,degree weight,closeness centrality,network centrality,and request influence degree).Then, it proposed a cache size allocation scheme based on node weight,to allocate router cache size proportional to node weight.Nu-merical experiments reveal that compared with the homogeneous assignment,the utilization rate of the router’s cache space in-creases by 8% at least and hit rate of the router’s cache space increases by 6% at least;compared with cache size allocation based on request influence degree,the utilization rate of the router's cache space increases by 3% at least and hit rate of the router’s cache space increases by 3% at least.关键词
