RMCAT @ IETF104 Prague
Mon 25 Mar 11:20-12:20 Karlin I/II

1. WG Status:

    SCREAM and SBD published as 8298 and 8382 respectively
    NADA last done
    GCC dormant and no further worked expected
    Coupled CC going through final steps

2. Hackathon Update (Jonathan Lennox):
    NADA algorithm being implemented reacting to CC Feedback
    Some interesting observations on very large feedback packets exceeding MTU:
    need to factor in impact of feedback size.

    Sergio: some implementation expected single sequence space
    Jonathan: could keep local mapping
    Colin: single has been suggested before but you can reconstruct this as said

3. RTP CC Feedback (Colin Perkins):
    -03 draft based on implementation experience at Bangkok hackathon
    Jonathan clarification: -03 format was used at Prague hackathon
    (-03 format is num_reports not end_seq_num)
    Must report on every active SSRC not every SSRC which is being CC'd - in
    SDP must be wildcard rtcp-fb.

    Jonathan: in offer/answer, answerer must only negotiate one feedback
    mechanism.

4. AOB:
    Sergio Mena: NADA actively being implemented for Firefox.
