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. 

Best Regards,
Xian (on behalf of all authors)

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.
