摘要 根据主动网络中的任何一个主动节点都可以用于放置缓存及其智能性等特征,提出一种基于主动网络的自适应网络缓存机制.即在自动构建层次拓扑的基础上,采用了缓存摘要技术进行通信协作,通过集中式管理缓存摘要的方法来减少协作通信量;并依照缓存服务器的负载情况进行缓存服务器之间的负载平衡.最后,使用trace-driven模拟方法,以Network Simulator仿真器作为模拟工具,模拟结果显示本文设计的系统与层式结构系统相比有较多优势. Based on the intelligence of the active network and its characteristic that any active node in the active network can be used for caching,an self-adaptive network caching mechanism is proposed:based on automatically constructing hierarchical topology,caching abstract technique is used for communication cooperation,and the quantity of cooperation communication is reduced by the centralized management of caching abstract.The load balance among caching servers is finished according to their loads.Trace-driven simulation algorithm and Network Simulator are used to simulate the mechanism.The result shows that the mechanism has much more advantages than the conventional systems.
