摘要

针对如何提高内容中心网络网内缓存性能的问题，提出一种基于层次划分的轻量协作的缓存存储策略。该策略通过Interest分组、Data分组以及路由器本地PIT表三者的协作把内容划分为多种优先级层级，使不同内容缓存在沿途的不同路由器。实验证明该策略可以有效地减少访问跳数，提高平均缓存命中率，降低服务器负载。

Abstract

For the issue of improving the performance of in-network cache in content-centric networking

a hierarchical division-based lightweight collaboration cache storage strategy was proposed. According to the strategy

content was grouped into different hierarchies by the cooperation Interest package

Data package and the local PIT of routers

so that the contents could be cached in different nodes along the delivery path. The performance of the scheme was eva-luated by comparing with the well-known schemes through simulation. Experimental results indicate that the scheme has good performance in reducing access hops

increasing the average cache hit ratio and reducing the server load.
