The Path Computation Element (PCE) facilitates Traffic Engineering (TE) based path calculation in large, multi-domain, multi-region, or multi-layer networks. [Stateful-PCE] provides the fundamental PCE communication Protocol (PCEP) extensions needed to support stateful PCE functions, without specifying the technology-specific extensions. This memo provides extensions required for PCEP so as to enable the usage of a stateful PCE capability in GMPLS-controlled networks.
