摘要
A method of delivering, by a first node in a first network, traffic in a dual-homed structure of a multi-protocol label switching-transport profile (MPLS-TP)-based network comprises the steps of: receiving, from a node of a second network, first information indicating that a link between the node of the second network and the first node is modified from a backup path link to an activated path link; transmitting the first information to one or more different nodes of the first network; receiving, from a second node, which keeps maintaining an activated path link with a node of a third network, among the one or more different nodes of the first network, second information indicating that the link between the node of the third network and the second node is the activated path link; and receiving traffic of the node of the second network via the link modified to the activated path link and delivering the traffic to the second node via the link between the first node and the second node based on the first information and the second information.;COPYRIGHT KIPO 2016
