A multi-protocol label switching (MPLS) packet network, methods and traffic engineering extensions to label distribution protocol are provided, capable of carrying traffic of multiple classes of service over the same label switch path.
1. A method for signalling between nodes in an MPLS network comprising nodes, the method comprising the steps of:
(i) generating signalling messages, each message comprising;
a set-up message object comprising:
a set-up message object header having a field for identifying a multi-class-of-service message object type; and
a multi-class-of-service set-up message object contents, including:
a field identifying the number of classes of service in the object contents, and
a traffic profile field for each class of service; and
(ii) exchanging the signalling messages between the network nodes.
