Liaisons

• Liaison from DSL Forum
• Subject DSL Forum Liaison to IETF ANCP about
  WT147
• Dear Mark/Jari
• We continue to track the progress of the ANCP WG
  with great interest. At the same time we wish to
  share with you our progress of the corresponding
  WT-147 work. Towards that end we attached the
  current version, the output of our Beijing 2007
  meeting.
• Our next meeting is in Nashville, August 27-30th,
  2007.
• Sincerely,
• Gavin Young
• DSL Forum Technical Chair
• Attachments WT-147

ANCP Multicast Handling

• Some observations of the chairs on the mailer
  discussion
• Use-cases/scenarios
• There appears to be broad agreement as these
  being plausible.
• Broad agreement that provisioned white/black
  lists are useful. Some technical aspects to be
  cleared up.
• To address specific cases, the non-default
  triggered query and response mode would seem to
  provide the missing flexibility that white/black
  lists dont have.
• Questions
• Do we want the framework requirements draft to
  address the complete protocol requirements for
  the multicast use-cases?
• Do we agree that we need optional mechanisms
  beyond white/black list to address the use-cases,
  eg query NAS (that fit within the ANCP WG
  charter)?

Extension of ANCP for Satellite and Terrestrial
Wireless Modem Networks

• Lloyd (lwood_at_cisco.com)
• internet-drafts/draft-floreani-ancp-wireless-00

12
Extensibility of ANCP

• How do we address extensibility of ANCP?
• Clearly, same protocol functions can be re-used
  in other access technology areas
• Two immediate proposals
• Need to decouple use of tech-type from protocol
  function
• Need to define extensibility scheme/guidelines.
