校园信息化网络安全的ICN缓存机制研究

摘要

Aiming at weak network in campus network and data center features, considering the cache size, caching, decision making and cache replacement algorithm, research and design a kind of cooperative caching mechanism for campus network security. Efficient information center network(ICN) cache mechanism has greatly improved the efficiency of the content distribution and compare the different combination strategy and algorithm for the analysis of network performance, cache cache based on low energy consumption delay to solve homogeneity and network billiton empty, etc. The problems of caching mechanism.Finally, through large-scale simulation experiments validate the feasibility of cooperative cache mechanism in the campus network security and cache performance.%针对校园网络中弱网元和数据中心等特性，综合考虑缓存大小、缓存决策和缓存替换算法，研究并设计一种面向校园网络安全的协作式缓存机制。高效的信息中心网络（ICN）缓存机制极大地提高了内容分发的效率，对比不同策略和算法组合来分析缓存网络性能，在低能耗时延的基础上解决同质化缓存和网络拓空等当前缓存机制存在的问题。最后通过大规模仿真实验验证该协作式缓存机制在校园网络安全中的可行性和缓存性能。
