摘要

针对信息中心网络（ICN）环境下缓存内容放置优化问题，提出一种边缘优先逐级反馈的缓存协作策略（ECCS）。该策略通过将缓存决策提前至请求转发阶段，将下游节点的缓存决策信息及内容统计信息逐级反馈给上游节点，以达到缓存信息即时更新、辅助上游节点完成协作缓存的目的。实验结果表明，ECCS 在服务负载减少率、平均跳数减少率和平均缓存命中率等方面与现有方法相比有显著优势。

Abstract

In order to optimize the replica placement in information centric networking

an edge-first-based cooperative caching strategy (ECCS) was proposed.According to the strategy

cache decision was made during the interest forwarding stage.The decision result and statistic information would been forwarded to upstream routers step by step.Utilizing the information

upstream nodes could update their cache information table immediately to achieve cooperative caching.The experimental results indicate ECCS can achieve salient performance gain in terms of server load reduction ratio

average hop reduction ratio

average cache hit ratio

compared with current strategies.
