摘要
IP组播在网络中的活动组很多时候会造成网络性能的下降以及实际效率低下的问题。本文提出了一种改善组播网络性能的方法,即聚合组播,并对聚合组播的生成算法进行了研究,在贪心算法的基础上给出了伪动态算法,最后通过实验对两种算法进行了分析论证并给出了结论。
A lot of active muhicast groups will cause the declination of network performance. One effective method, which is called aggregated muhicast and can improve the performance of multicast network, is introduced, this paper focuses on the research on algorithm of aggregated multicast and proposes p-dynamic algorithm based on studying the deficiency of greedy algorithm. With the simulation experiment results are analyzed.
