| 摘 要： | 提出了一种基于分簇结构的混合分发算法,算法采用分簇的方法将流媒体中的节点资源进行簇划分,形成由簇头、簇内节点构成的分簇网络结构,簇头与簇内节点通过拉拽算法来获得数据,而簇头间采用推送分发算法.仿真结果表明,该算法能提高数据块复制速度,减少数据传播时延,有效降低系统的控制开销,提高了播放连续度.

| Abstract: | A hybrid scheduling algorithm based on clustering is presented. In the algorithm, node resources are divided into cluster head and cluster nodes by clustering method and form a clustering network structure. For the network, data is obtained by push algorithm between cluster heads and heads, while pull algorithm between cluster heads and inter-cluster nodes. Simulations show that the algorithm can increase the speed of data block duplication, reduce the data propagation delay and the control overhead of stre... |
