A Control Package for BFCP

• Individual contribution to deal with floor
  control in the MCCF
• When FCS co-located with the MS
• AS co-located with the FCS doesnt need this
• No explicit milestone for this in the charter,
  but it is related to the mixing stuff
• Parallel/complementary development with the
  mixing work (e.g. find additional requirements)

Requirements

• Need to provide the AS with means to configure
  and manage the moderation of a MS conference
  instance
• Is conferencing the only target? (e.g. Push To
  Talk)
• Need mapping of media labels with floors
• Which mixed streams are available?
• How to enforce decisions?
• Need to support RFC4583
• Is an explicit add participant needed?
• Need an event notification mechanism
• Which events should be triggered? (apart from
  granted/not granted anymore)

RFC4583 Support

• RFC4583 specifies a way to negotiate a BFCP
  connection in SIP/SDP (COMEDIA)
• Also provides clients with needed info (FCS
  transport address, BFCP-related identifiers,
  etc.)
• However, it assumes the FCS is already aware of
  the participant
• Issue in signaling (INVITE precedes ltjoingt)
• Proper synchronization between 3PCC and Control
  Channel is needed

RFC4583/3PCC v1

RFC4583/3PCC v2

Final Remarks

• Is the draft on the right track?
• Are more directives/events needed?
• Which signaling pattern is to be preferred?
• Should it be an extension of the mixing
  package(s), or a package on its own?
• Extension mechanism still undefined
• May extend optional packages
• Conferencing might not be the only target
• Suggestions? Comments?
