METHOD AND APPARATUS FOR PROTECTION SWITCHING IN ROOTED MULTIPOINT (RMP) CONNECTION NETWORKS

摘要

A method of operating a root node in which the root node transmits/receives traffic with a plurality of leaf nodes through a plurality of working paths is disclosed, the method including receiving, from a first leaf node, a first signal failure (SF) message indicating an occurrence of a failure on a first working path of the first leaf node, receiving traffic from the first leaf node by switching the first working path to a first protection path, and receiving traffic from remaining leaf nodes aside from the first leaf node while maintaining the working path.

1. A method of operating a root node, the method comprising:
receiving, from a first leaf node, a first signal failure (SF) message indicating an occurrence of a failure on a first working path corresponding to the first leaf node from among a plurality of leaf nodes that transmits/receives at least one of transmitting traffic and receiving traffic through a plurality of working paths; receiving, from the first leaf node by switching the first working path to a first protection path, receiving traffic; and receiving, from remaining leaf nodes aside from the first leaf node, receiving traffic through each of remaining working paths aside from the first working path.
