Abstract
An apparatus comprising a receiver configured to receive a first path computation request (PCReq) message from a path computation client (PCC) requesting path computation for a label switched path (LSP) in a network, wherein the PCReq message indicates a time interval scheduled for the LSP to carry traffic, a processor coupled to the receiver and configured to compute a path in the network for the LSP by determining that the path satisfies a network constraint in the scheduled time interval, and reserve a network resource on a link along the path computed for the LSP, wherein the network resource is reserved in advance for the scheduled time interval, and a transmitter coupled to the processor and configured to send a path computation response (PCRep) message to the PCC indicating the path computed for the LSP in the scheduled time interval.
