信息中心网络(information-centric networking
ICN)与传统IP网络的重要区别在于,前者的路由器节点具备缓存能力,能将热门内容推送到更靠近客户的网络边缘,从而降低客户获取内容的时延。然而ICN中的节点缓存特性会导致传统的自适应流媒体协议出现视频抖动甚至播放中断,降低客户的观看体验。提出了ICN中的动态自适应流媒体算法,在保证客户端播放流畅的同时,尽可能地提升视频片段的码率,提升客户的观看体验。通过在现有的ICN平台中进行仿真实验,证明了该自适应算法在性能上优于传统的算法。
Information-centric networking(ICN)has different type of router node from the traditional network
which has caching facilities
and popular content will be pushed to the edge of the network closer to the user
reducing the delay of the user's access to the content. However
ICN's caching will result in the shake or even the interruption of video play when client uses the traditional adaptive streaming protocol
reducing the user's viewing experience. An algorithm for dynamic adaptive streaming in ICN was proposed
ensuring smoothly playback as well as improving the average bitrate of play thus to enhance the user's viewing experience. Simulation experiment on the existing ICN platform proves that the adaptive algorithm performs better than the traditional algorithms.
