提出了一种应用于内容中心网络的缓存策略,对高热度内容进行分布式缓存,允许缓存节点之间协作,保证热度高的内容在缓存中生存更长的时间,并在内容请求过程中利用跟踪节点实现缓存内容的定位,允许内容请求用户从网络中参与协作的缓存节点获取被请求内容的不同部分,达到分布式缓存协作的目的,提高网络中缓存资源的利用率,降低内容请求用户获取内容的时间.仿真结果表明,该策略能有效减少网络的平均时延.
This paper proposes a caching strategy applied to the content center network, which distributes the cache of high heat content and allows the cache nodes to cooperate to ensure that the hot content can survive longer in the cache and be used in the content request process The tracking node realizes the positioning of the cached content and allows the content to request the user to obtain different parts of the requested content from the caching nodes participating in the collaboration in the network to achieve the purpose of distributed caching cooperation and improve the utilization of the cached resources in the network and reduce the content to request the user to obtain Content time.The simulation results show that the strategy can effectively reduce the average delay of the network.
