For a Path Computation Element (PCE) to perform its computations, it is important that Link-State (and TE) information be complete and accurate each time. This requires a reliable Link-State Synchronization mechanism between the PCE and path computation clients (PCCs), and between cooperating PCEs. The basic mechanism for Link-State Synchronization is part of the PCEP Link-State (and TE) draft. This draft presents motivations for optimizations to the base PCEP Link-State (and TE) procedure and specifies the required Path Computation Element Communication Protocol (PCEP) extensions.
