Abstract:
1. A method for establishing traffic engineering (TE) tunnels, the method comprising: sending, by a first node, a first Path message for establishing a first unidirectional TE tunnel from the first node to a second node, wherein the first Path message comprises: (1) triggering information configured to trigger the second node to send a second Path message for establishing a second unidirectional TE tunnel from the second node to the first node and (2) bandwidth information that specifies a bandwidth for the second unidirectional TE tunnel, wherein the bandwidth for the second unidirectional TE tunnel is different from a bandwidth of the first unidirectional TE tunnel; receiving, by the first node, the second Path message and a first Resv message responsive to the first Path message; and sending, by the first node, a second Resv message responsive to the second Path message.
