Dear PCErs, This draft proposes three functions that can help to optimize the LSP DB Synchronization process for stateful PCEs. It merges some content from draft-ietf-pce-stateful-pce and the draft draft-zhx-pce-stateful-lsp-sync-00.
This new version have addressed the comments received with regard to both parts. Please review this version and any comments/suggestions are welcome.

Filename: draft-minei-pce-stateful-sync-optimizations Revision: 01 Title: Optimizations of Label Switched Path State Synchronization Procedures for a Stateful PCE Creation date: 2013-12-02 Group: Individual Submission Number of pages: 19 URL: http://www.ietf.org/internet-drafts/draft-minei-pce-stateful-sync-optimizations-01.txt Status: http://datatracker.ietf.org/doc/draft-minei-pce-stateful-sync-optimizations Htmlized: http://tools.ietf.org/html/draft-minei-pce-stateful-sync-optimizations-01 Diff: http://www.ietf.org/rfcdiff?url2=draft-minei-pce-stateful-sync-optimizations-01 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. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
