METHOD FOR EXCHANGING INFORMATION FOR ESTABLISHING A PATH BETWEEN TWO NODES OF A COMMUNICATION NETWORK

摘要

An exemplary method and apparatus are provided for exchanging information for establishing a path between a first node and a second node of a communication network. The first node and the second node are adapted to send continuity check messages to monitor the established path. The technique includes generating, at the first node and at the second node, at least one link state message according to a routing protocol; inserting continuity check link state information into the at least one link state message; and exchanging between the first node and the second node, the link state messages for computing the path. The continuity check link state information are indicative of at least one rate of transmission of the continuity check messages supported by the first node and the second node.

1. A method for exchanging information for establishing a path between a first node and a second node of a communication network, said first node and said second node being adapted to send continuity check messages to monitor said established path, said method comprising:
a) generating, at said first node and at said second node, at least one link state message according to a link state routing protocol; b) inserting continuity check link state information into said at least one link state message; and c) exchanging, between said first node and said second node, said link state messages for computing said path; wherein said continuity check link state information are indicative of at least one rate of transmission of said continuity check messages supported by said first node and said second node.
