GMPLS Signaling Applicability Statement

• IETF 55, Atlanta
• draft-awduche-ipo-gmpls-signaling-applicability-00
  .txt
• Daniel Awduche (awduche_at_isocore.com)
• Adrian Farrel (afarrel_at_movaz.com)

2
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

4
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

5
Key Aspects Covered by the Draft

• Focused on provisioning
• Survivability
• Flexibility
• Interoperability

6
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)

7
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
