Identity Adhoc - Summary

• Do we agree we have a problem?
• Unanimous Agreement that we do have a problem.
• If we have a problem, what should be the next
  step?
• No point in mapping solutions until we all agree
  on requirements.
• Next step is to work the requirements until we
  have better agreement.
• Who is willing to be involved in ongoing work
  (e.g., drafting, reviewing, proposing
  solutions)?
• Several folks indicated interest and willingness
• Is it appropriate to keep this as a DISPATCH
  topic and try to take more positive steps at
  IETF77?
• Need to actively work on the topic between now
  and IETF-77.

6
Call Control for UUI (CCUS) Status

• New proposed charter text sent to the list for
  discussion
• Changes based on feedback at IETF-75 and mailing
  list discussion
• Discussion on DISPATCH list on charter scope and
  focus is ongoing
• More feedback welcome
• No revisions of requirements or mechanism drafts
• Need to finish charter discussion so we can get
  back to this interesting work

SIP Overload Control

• SIP Overload Control WG Charter Proposal
• Objective of the proposed working group is to
  develop mechanisms for SIP overload control. Two
  complementary approaches
• Preventing overload in SIP servers by adjusting
  the incoming load to a level that is acceptable
  for this server.
• Preventing overload in SIP servers by
  distributing load control filters to SIP servers
  that throttle calls based on their destination.
• Status feedback addressed
• Mailing list SIP Overload Control
• Three drafts on SIP Overload Control
• draft-ietf-sipping-overload-design-02
• draft-hilt-sipping-overload-07
• draft-shen-sipping-load-control-event-package-03
• Expert review on current drafts (reviewers
  welcome!)
• Next step charter WG?
