The reason this documents Updates RFC5104 is that it clarifies that the
TMMBR message that is defined in 5104 can also be used for pause if one
sets bandwidth to 0. This is important to know also for anyone not
intending to implement PAUSE and Resume semantics.
I realize that this is not clearly stated in the introduction. Perhaps
something we should address by adding a sentence or two to this
paragraph from Section 1.
The Temporary Maximum Media Bitrate Request (TMMBR) message of CCM is
used by video conferencing systems for flow control. It is desirable
to be able to use that method with a bitrate value of zero for pause,
whenever possible.
Cheers
