[Loren Schwiebert <loren@bert.eng.wayne.edu>]

As the subject line implies, I would like to know how bandwidth is
allocated/reserved in the backward direction of an ABR connection.
Specifically, assume a situation where the flow of data is
unidirectional.  In this case, the destination sends only the backward
RM cells.  How does the network determine how much bandwidth to
allocate for such cells?

I realize that we could specify an MCR > 0, but is there some other
mechanism that I have missed.  I read through the TM 4.0
specification, but was unable to find any explicit discussion of
this issue.  If someone could give me a pointer to this discussion
within the specs, that would also be great.

I am also curious how the allocation of bandwidth for the backward
RM cells is handled for a point-to-multipoint connection.

Thanks in advance for your assistance.

Sincerely,

Loren
