【摘要】 针对网络中存在大量重复流量的问题,基于大规模接入汇聚网络创造性地提出了抵近式缓存的思想,利用大规模接入汇聚路由器覆盖广、汇聚能力强的特点,在骨干网中,将热点内容单播推送至尽可能逼近用户的网络接入点缓存,在接入网中,将网络接入点中的缓存内容以多播方式智能高效地分发至用户,从而为提高用户体验质量、减少网络流量、降低服务器负载提供了一种解决途径。更多还原

【Abstract】 Aiming at the problem of many repeated traffic in the network, the idea of offset-caching(OC) was put forward creatively based on the idea of large-scale access convergence network. In the backbone network, the hot content was pushed to the network access point as close as possible to the users. In the access network, the cached content in the network was multicasted access point to the users. The idea would provide a resolution to improve the quality of the user experience, reduce the network traffic and the server load.更多还原
