The Path Computation Element Communication Protocol (PCEP) allows Path Computation Clients (PCCs) to request path computations from Path Computation Elements (PCEs)@ and lets the PCEs return responses. When computing or reoptimizing the routes of a set of Traffic Engineering Label Switched Paths (TE LSPs) through a network@ it may be advantageous to perform bulk path computations in order to avoid blocking problems and to achieve more optimal network-wide solutions. Such bulk optimization is termed Global Concurrent Optimization (GCO). A GCO is able to simultaneously consider the entire topology of the network and the complete set of existing TE LSPs@ and their respective constraints@ and look to optimize or reoptimize the entire network to satisfy all constraints for all TE LSPs. A GCO may also be applied to some subset of the TE LSPs in a network. The GCO application is primarily a Network Management System (NMS) solution.
