摘要
信息中心网络(ICN)已经展现出可以解决多种网络问题的趋势。与此同时,信息中心网络还有许多问题需要去解决,以推进这个非常有前途的架构。在这篇文章中,我们主要讨论两个问题:1)如何定位或选择网络中的节点作为缓存节点;2)缓存节点缓存什么样的内容使得缓存利用率较高。这篇文章通过介绍基于势能的缓存算法,使得在任意图网路中通过合理分配缓存节点和缓存内容达到较高的缓存利用率。通过和CATT的比较,请求节点的接入代价降低,内容路由器命中率增加。
ICN(Information Centric Networking) has shown the trend that can solve the problem of multiple network. Meanwhile,there are many problems need to solve, in order to promote this very promising architecture. In this paper, we mainly discuss twoproblems: how to locate or select node to cache the distributed contents? And how are these content distributed or cached by takingadvantage of cache in network? The paper through introducing the cache algorithm based on potential that achieve high cache utili-zation by reasonable distribution of the cache in network nodes in arbitrary topology.Through the comparison with CATT, the algo-rithm had make that the access cost of nodes in network reduced and increase the cache hit ratio.
