在深入研究现有的能够减少组播转发状态和组播抖动，以及高效容错多协议标签交换组播策略的基础上，提出了一种综合的多协议标签交换组播策略，即基于聚合和隧道技术的组播策略，采用组聚合机制和隧道技术，能够更有效地缓解有限标记空间，增强组播的健壮性和稳定性。On the basis of researching existing multicast approaches in Multiple Protocol Label Switch (MPLS), a new strategy named Aggregated and Tunnel-Based MPLS Multicast (ATMM) is proposed. ATMM merges group aggregation and tunnel technology and can alleviate limited label space, and strengthen the multicast robustness and stabilization.
