提出了一种新的编码数据分发算法,该算法通过收集每个多播路径簇上承载业务信息的带宽,来确定编码后数据的分发策略,使编码节点能够对带宽不相同的数据进行处理并在解码节点正确解码,从而更加贴近现实网络。仿真结果表明,该算法在资源消耗和网络均衡方面较传统的多播算法有更好的表现。
In this paper, a new algorithm for encoded data distribution is proposed. The algorithm through collecting the bandwidth of information beared by each multicast path cluster to determine the encoded data distribution, allowing the encode node can process the data of different bandwidth and correctly decoded in the decoding node, and thus closer to the real network. Simulation results show that compared with traditional multicast algorithms, performances of our algorithm improved at a great extent in resource consumption and load balance.
