摘　　要：为了更好解决目前流媒体服务体系中存在的节点随意性问题,提出一种基于DHT的双层环的流媒体服务体系,该体系运用Vivaldi方法计算出节点在网络中的位置,这样流媒体数据只需要少量的网络跳数,就能找到目标位置,很好地解决"路由绕路"问题,从而提高流媒体服务系统的效率和可扩展性。Brings in a double-layers streaming media service system based on DHT for better solving the matter of the arbitrariness of the nodes in the current streaming media service system, so as to enlarge and optimize the efficiency and scalability of the streaming media service system. Ap- plies the Vivaldi methodology into the aforesaid system to substantially reduce the frequent of hops of the network in locating the target point, as well as eliminate the ＂detour routing＂ effect caused by nodes.
