摘要： 在分析MMT, AMFM和ATMM等组播方案的基础上，针对其单一管理节点容易成为骨干网上组播的瓶颈，影响MPLS骨干网上组播树的健壮性问题，提出一种环形管理组播树的策略，通过对该策略的仿真分析，表明该策略能有效地解决单个管理节点超载和组播聚合树的信息丢失等问题，提高骨干网络中组播聚合树的效率和健壮性。

Abstract: On the basis of analyzing multicast schemes, such as MMT, AMFM and ATMM, this paper proposes an annular management strategy for multicast tree in MPLS network, aiming at that single management node brings bottleneck of the multicast tree and affects haleness of the MPLS network. This tactics can have an effect to resolve problems, such as overload and the drop of the information of multicast tree.

Key words: annular management, Multi-Protocol Label Switching(MPLS), multicast
