| 1. A method for processing protection signaling messages in a node in an optical network, comprising:
treating protection signaling messages with a highest priority when there are resource contentions with other types of signaling
messages;
treating all protection signaling messages in a single first-in-first-out fashion if there are multiple protection signaling
messages waiting to be processed in a single node;
merging two channel failure response messages, each of said two channel failure response messages generated upon receipt of
a corresponding channel failure message, destined for a same next node into one single combination channel failure response
message in a single node; and
transmitting the single combination channel failure response message to the same next node in the optical network.
