All things related to multicast

[Alan Crosswell <>]

Multicast WG BoF Wed Oct 15, 2008

There were about 20 attendees.  Elaine has the list.
Presentation slides will be posted to the I2MM web site once I receive them.

Items discussed follow:

* High bandwidth multicast over WiFi
  - no progress on getting any significant information from vendors other
    than the realization that there are a number of problems with
    rate limiting, flooding, sending all multicast down tunnels to APs, etc.
  - See Bruce's mail regarding Cisco APs and roaming.

* New Applications
  - Philadelphia Orchestra global concert series
    - They experienced significant technical issues with campus multicast
      - This did lead to several new campuses now able to do interdomain
  - "Move network" cache servers (unicast) beta w/Dave Devereaux-Weber
  - Intercast multicast to storage for entertainment content being
beta-tested
    at a couple of member schools.
  - Vbrick multicasting powerpoint.etc. to go along with the audio/video
  - Inuk Networks - software player in demo room

* Doing it without SAP
  - Hitoshi referenced his
draft-asaeda-mboned-session-announcement-req-00.txt
    and ask that we support moving this draft from individual to the group.
  - Hitoshi & Kazuhiro Mishima presented a "channel-reflector" system
this is
    in activie development and solicited participation.
    See http://demo.channel-reflector.net
  - Tsuyoshi Hisamatsu briefly presented his latest DVTS follow-ons:
    - DVRTP gldvshow DVTS client using OpenGL
    - MPEG2-H.264 realtime transcoder

   - Rich Mavroegeanes showed a Vbrick-developed SAP-replacement that
uses RSS
     and asked for interested people to contact him to provide input,
     suggestions, possibly generate an I-D.
     Includes an RSS listener for Sametime
     Vbrick reflector is used for interdomain unicast, local multicast
     Presentation viewer as mentioned above.

* SSM
  - Vbrick now supports SSM in their products (yay!)
  - Apple still no SSM and no liklihood of this every being fixed.
  - Silverlight doesn't support any multicast

* Merit doing measurement & multicast monitoring using Zenoss

* New Chair for the WG
  Richard Machida has graciously agreed to take over as the Chair of the WG
  effective today.  Thanks, Richard, I'm off now to remove myself from
Sympa:-)
