摘要

针对命名数据网络（NDN）内容请求节点容易忽略邻近节点缓存的问题，基于节点兴趣集群思想，提出一种面向邻近缓存的引导式便捷内容路由机制。首先通过构建节点兴趣集群将节点分为若干区域进行缓存通告；然后设计报文与便捷路由转发表项；最后选择最优路径发送请求数据。理论分析与仿真结果表明，该机制能够充分利用邻近节点缓存，有效地降低了用户平均时延，服务器负载减少约30%。

Abstract

It is very easy for the nodes in named data networking to ignore the neighbor nodes. To solve this issue

a leading routing mechanism for neighbor content store was proposed. Firstly

through building the interest clusters

the nodes were partitioned to different reigns to announce the information of content store. Secondly

the packets and the fast routing tables were designed. Finally

the best path was chosen to send the interest packets. The theoretical analysis and simulation results show that

this mechanism adequately uses the neighbor content and effectively decreases the average network delay. The server load is reduced by 30%.
