Changes from draft-ietf-rmt-bb-tfmcc-00.txt:

* In section 3.1, set the initial sending rate to 1 packet per maximum
RTT

* In section 3.2, decreased R_max decay factor to 0.9 (from 0.95)

* In sections 3.3, 3.4, 3.6, changed incorrect notation MaxRTT to R_max

* In section 3.3, corrected maximum increase to "8s/R_max bits/s every
R_max" (from 1 packet/RTT^2)

* In section 3.4, added the sentence 
"Feedback that causes the corresponding receiver to be selected as CLR,
but was from a non-CLR receiver at the time of sending also
contributes to the feedback suppression." for clarity

* In section 3.4, changed the duration of a feedback round by adding
the sentence:
"After a time span of T, the feedback round ends if non-CLR feedback
was received during that time.  Otherwise, the feedback round ends as
soon as the first non-CLR feedback meesage arrives at the sender but
at most after 2T."

* In section 3.6, changed wording of slowstart increase limit and
added sentence "As in normal congestion control mode, the receiver
with the smallest reported rate becomes CLR." for clarity.

* In section 4.5, changed the wording of the feedback mechanism for
non-CLR receivers. Non-CLR receivers always set a feedback timer at
the beginning of a feedback round.

* In section 4.5, added a sentence specifying that a data packet
indicating a new feedback round cancels all feedback for older rounds.

* In section 4.5, added a paragraph on feedback suppression in the
face of rapidly changing calculated rates and introduced X_fbr, the
calculated rate of a receiver at the beginning of a feedback round, to
prevent a feedback implosion.
