GMPLS Signaling Applicability Statement IETF #55, Atlanta draft-awduche-ipo-gmpls-signaling-applicability-00.txt Daniel Awduche Adrian Farrel

Background Applicability statements are the major outstanding work items for the IPO WG One class of applicability statements relates to GMPLS signaling protocols: –draft-ietf-mpls-generalized-signaling-09.txt –draft-ietf-mpls-generalized-rsvp-te-09.txt –draft-ietf-mpls-generalized-cr-ldp-07.txt The other category of applicability statements relates to GMPLS routing Applicability statements, in this context, delineate domain specific capabilities and limitations of the pertinent protocols

Why is This Draft in the IPO Working Group? It is a chartered deliverable It delineates the subsets of GMPLS signaling functionality that are useful within the context of IPO Networks

What Does the Applicability Statement Cover? Applicability of GMPLS signaling to IPO networks Highlights relevant capabilities of GMPLS signaling for IPO networks Includes premise and restrictions Indicates subsets of messages and objects that are needed to support specific IPO functions using GMPLS

Key Aspects Covered by the Draft Focused on provisioning Survivability Flexibility Interoperability

Next Steps Need to make improvements in next revision: –Distinguish between capabilities according to application context signaling between optical switches only signaling between MPLS/IP switches and optical switches –Provide quick-reference table of messages and objects by function Thanks for the feedback (on and off the list)

Actions Need to make some improvements in next revision: –Distinguish between pertinent capabilities according to class of switch signaling between optical switches only signaling between MPLS/IP switches and optical switches –Provide quick-reference table of messages and objects by function Request to adopt this draft as a WG doc
