摘要
作为下一代网络的重要部分,分组传送网当前的热点是源于MPLS技术的T-MPLS。分组传送网对生存性有着比TDM传送网更多的要求,这对T-MPLS是很大挑战。本文提出了一种基于FRR的双重自愈机制,并给出了相应的信令扩展,它能显著改善网络的自愈性能。
Packet transport network is a key part of NGN. The present attention is focused on T-MPLS which comes from MPLS. PTN has more requirement about survivability than legacy TDM-based transport network, so it is a great challenge to T-MPLS. This paper puts forward a new method called FRR-based dual self-heal mechanism to address survivability in T-MPLS and presents responding extensions to signaling protocol for FRR. It can greatly enhance performance of self-health.
