基于边缘簇组播树构造算法的分析与改进

Analysis and Improvement of Edge Clustered Tree Algorithm for Building Multicast Tree

在分析IP域中支持QoS的基于边缘簇的组播树构造算法的基础上,针对该算法生成的组播树的总体路径费用较高的问题,提出了一种改进的基于边缘簇的组播树构造算法IECT,该算法可在承载组播流量的网络核心域构造出总体路径费用较小的组播分发树。

Analyzes ECT, the Edge Clustered Tree algorithm for building QoS multicast distribution tree in IP domain. Aiming at the problem of the total path cost of multicast tree built by ECT is high, it proposes IECT, the Improved Edge Clustered Tree-building algorithm, which can build a multicast tree with lower total path cost in core domain network carrying multicast traffic.
