Abstract
A label switched path is determined in a communications multi-service network comprising a plurality of nodes interconnected via quality of service capable tunnels to provide a QoS guarantee for a session in which resource availability from the network edge to multiple central stages and resource availability from the multiple central stages to the destination edge are established. A series of quality of service capable tunnels is selected by offering a plurality of candidate central stages to the destination edge and allowing the destination edge to select a complete path across the network. A label stack comprising a set of four labels is attached to a payload to define a selected sequence of tunnels.
