  1. CLUE Framework Interim September 17, 2013 Mark Duckworth draft-ietf-clue-framework-11

  2. Framework Agenda • Switched captures in multipoint • Roles • Editorial suggestions • #33 Security • #35 framework and data model consistency • #36 encoding and encoding group parameters • #43 remove consumer choice attributes • #44 remove detail about ack’ing Advertisement

  3. Switched Captures – next steps • We still have fundamental open issues regarding an important class of scenarios from the use cases and requirements documents • draft-duckworth-clue-switching-example-01 points out some issues, suggests solutions, but still needs work • draft-groves-clue-multi-content-00 raises many questions and suggests solutions, but hasn’t had any discussion yet • Need more discussion on the email list before updating individual drafts or any working group documents • includes tickets #19 and #26

  4. Roles – next steps • draft-groves-clue-role-clarifications-00 • Email discussion started, need more input on the list

  5. Mary’s suggestions • Email list discussions Mary started • Make Framework Standards Track (currently Informational) • use MUST and SHOULD etc., in some cases • Various proposals for clarification • Next step – Mark to incorporate the suggestions, and continue email discussion for items that don’t appear to be settled yet

  6. #33 security • Framework should mention security threats • Mary said she will start • Input from group would be helpful

  7. #35 framework and data model consistency • Recent updates to both documents bring them in line • This will be an ongoing task to keep them consistent • Keep open for now, as reminder to keep them consistent for any new changes • No immediate action required

  8. #36 computational complexity parameter • Discussed at IETF87 • Framework should say there are Encoding parameters that are codec-specific • framework should not itemize or give detail on codec specific parameters • Remove max pixels per second from Encoding Group constraints • this is codec-specific. There is no good way to use this in a way that applies to different codecs in the same encoding group. • Mark to propose specific changes to framework • will need some corresponding changes to data model

  9. #43 - Remove idea of attributes with Consumer choices • Problem: Provider can Advertise multiple values for scene-switch-policy, and Consumer can choose in the Configure message • email list discussion has pointed out unintended complications and side effects of this • Solution: do not allow Consumer to choose the value. Provider can Advertise different Captures with different values, just like all the other attributes. • Mark to propose specific change to framework • will need corresponding change to data model also

  10. #44Remove detail about ack’ing Advertisement with a Configure • From IETF87 discussion – details should not be in the framework • Mark to propose specific change to framework
