The IESG has received a request from the Path Computation Element WG (pce) to consider the following document: - 'Optimizations of Label Switched Path State Synchronization Procedures for a Stateful PCE' <draft-ietf-pce-stateful-sync-optimizations-08.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-02-28. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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.
