Title : Optimizations of Label Switched Path State Synchronization Procedures for a Stateful PCE Authors : Edward Crabbe Ina Minei Jan Medved Robert Varga Xian Zhang Dhruv Dhody Filename : draft-ietf-pce-stateful-sync-optimizations-02.txt Pages : 23 Date : 2015-01-13 Abstract: A stateful Path Computation Element (PCE) has access to not only the information disseminated by the network's Interior Gateway Protocol (IGP), but also the set of active paths and their reserved resources for its computation. The additional Label Switched Path (LSP) state information allows the PCE to compute constrained paths while considering individual LSPs and their interactions. This requires a reliable state synchronization mechanism between the PCE and the network, PCE and path computation clients (PCCs), and between cooperating PCEs. The basic mechanism for state synchronization is part of the stateful PCE specification. This draft presents motivations for optimizations to the base state synchronization procedure and specifies the required Path Computation Element Communication Protocol (PCEP) extensions.
