Abstract: A method implemented by an end user device in a network, comprises transmitting user service expectation data to a network element (NE) in the network, the user service expectation data describing an expected network attribute of a path between the end user device and a destination, receiving path aware network data from the NE in response to transmitting the user service expectation data describing the expected network attribute to the NE, the path aware network data comprising a path index, path quality information, and data plane information, the path index identifying the path, the path quality information describing a network attribute supported by the NE on the path, and the data plane information comprising information associated with a protocol by which to transmit a data packet along the path, and transmitting the data packet along the path based on the data plane information.

Abstract: A method implemented by a network element (NE) in a network receiving, by the NE, an advertisement comprising preferred path route (PPR) information describing a path from an ingress NE to an egress NE in the network, the PPR information comprising a PPR identifier (PPR-ID) and an attribute associated with a resource to be reserved on the PPR, transmitting, by the NE, the advertisement comprising the PPR-ID and the attribute associated with the resource to be reserved on the PPR to another NE in the network, and updating, by the NE, a local forwarding database to include the PPR information in association with the egress NE in response to the NE being identified in the PPR information.
