Abstract
Disclosed is a network element (NE) comprising a receiver configured to receive a path computation request, a path computation element (PCE) coupled to the receiver and configured to compute a group of network paths through a network of NEs operating in a network stratum in response to the path computation request, wherein each network path comprises one or more physical links, and compute at least one constraint for each physical link, and an abstraction module coupled to the PCE and configured to receive the computed network path set and constraints, compute one or more abstract links that describe the network path group, and compute a constraint for each abstract link based on the physical link constraints.
