| Abstract: | To improve the restoration performance of a multicast service of multi-protocol label switching transport profile (MPLS-TP) enabled optical network,this letter proposes a local-node initiated fast restoration (LNIFR) scheme for MPLS-TP optical multicast service.The proposed scheme allows the local node to establish a segment of fast loopback label switch path by the local node along the upstream of the failed node or link to the nearest downstream node.The fast restoration of optical multicast trees is real... |
