5. Milestones Jun 2008 - Submit first draft of applicability statement (for inter-area MPLS and GMPLS Traffic Engineering) -> On the agenda Done - Submit PCE P2MP PCEP protocol extensions to the IESG to be considered as an Proposed Standard RFC -> RFC 6006 Feb 2009 - Submit the PCE MIB Internet-Draft to the IESG for consideration as Proposed Standard -> Work in progress Feb 2009 - Evaluate WG progress, recharter or close -> Action in progress with the chairs (ticket opened)

6. Documents • Two new RFCs since Maastricht • RFC 6006: PCEP Extensions for P2MP TE-LSPs • RFC 6007: Synchronized VECtor List • IESG Processing • Inter-layer Requirements: publication requested • Manageability Section (Historic): announcement sent • Expired • Textual Conventions and Discovery MIB

7. Not on the Agenda • draft-ietf-pce-gmpls-aps-req • solution (WG) I-D on the agenda • draft-ietf-pce-inter-area-as-applicability • new WG I-D (addressing an old milestone) • draft-ietf-pce-inter-layer-ext • implementations? • draft-ietf-pce-pcep-mib • work in progress • draft-ietf-pce-vpn-req • waiting for solutions • draft-ietf-pce-vendor-constraints • interest seems to be still there: editing to be discussed
