Thus, a PCE is an entity capable of computing complex paths for a single or set of services. A PCE might be a [[Computer network|network]] node, network management station, or dedicated computational platform which is aware of the network resources and has the ability to consider multiple constraints for sophisticated path computation. PCE applications include computing Label Switched Paths for MPLS and GMPLS Traffic Engineering. The various components of the PCE architecture are in the process of being standardized by the IETF's ''PCE Working Group''<ref name=pce>IETF's Working Group, [http://www.ietf.org/html.charters/pce-charter.html "Path Computation Element (pce)"]</ref>.

PCE represents a modern vision of networks where route computations should more or less be separated from actual packet forwarding.
