摘要： 根据动态组播代理的移动组播算法原理，提出一种移动组播协议，采用新的快速组播切换机制，以时间量度和距离量度为依据，动态选择组播代理。仿真结果表明，该协议避免组播转发树的频繁重构，降低组播切换延迟，具有次优的组播传输路径，可以与现有网络协议相融合。

Abstract: According to the principle of mobile multicast algorithm for dynamic multicast Agent, this paper proposes a mobile multicast protocol. It adopts a novel fast multicast swithc mechanism and selects the multicast Agent dynamicly according to the time measurement and distance measurement. Simulation results show that this protocol avoids the frequent reconstruction of multicast delivery tree, decreases the multicast switch delay. It has the near-optimal multicast transfers path and capability of integration with the existing network protocols.
