Claim:
1. A method comprising: storing, in a memory accessible by a path computation client (PCC), at least one profile identifier; generating, by the PCC, a path computation element communication protocol (PCEP) request message comprising a destination identifier and a profile identifier of the at least one profile identifier, wherein the generating the PCEP request message is in response to detecting a network state that is local to the PCC by determining which of the at least one profile identifier is the profile identifier corresponding to a network service associated with a peer node and determining that a path from the PCC to the peer node does not exist for the profile identifier, wherein the peer node is a destination associated with the destination identifier; transmitting, from the PCC, the PCEP request message to a path computation element (PCE); and receiving, by the PCC from the PCE, a PCEP reply message comprising a path from the PCC to the destination associated with the destination identifier, wherein the path satisfies at least one path constraint, stored remote from the PCC, corresponding to the profile identifier.
