There were no technical issues found. If anyone has any
other issues such as scheduling, or identifying data-limited intervals –
then it would be good to know. Some NITs are listed below: ----------------------------------- General changes: Isn’t -> is not Don’t -> do not --------------------------------------- 1. Introduction TFRC is designed to be reasonably fair
when competing for bandwidth with TCP flows, where a flow is
"reasonably fair" if its sending rate is generally within a factor of two
of the sending rate of a TCP flow under the same conditions
[ref?]. ----- 3.1 TCP Throughput Equation " Ideally we'd prefer a throughput
equation based on SACK TCP," -> Ideally we would prefer.. ------ 4. Data Sender Protocol "If the sender does not receive a feedback report for four
round trip times, and the sender has not been idle over that entire
period, then it cuts its sending rate in half." It is to be noted that the sender cuts the rate into half
during idle periods too..so its better to avoid discrepancy.. -> If the sender does not receive a feedback report for four
round trip times then it cuts its sending rate in half. ---- Section 4.3 "However, any interval that covers
the transmission of at least two data packets
is not a data-limited interval for this sender." This is not clear. `data-limited interval' ->
'data-limited' ``if'' -> "if" ----- C.1 "..an idle period, the first feedback packet receives
reports a receive rate of one packet per round-trip time, " -> ..an idle period, the first feedback packet received
reports a receive rate of one packet per round-trip time, "Standard TFRC after long data-limited periods:
[RFC3448] does not distinguish between data-limited and
not-data-limited periods." -> Standard TFRC after long data-limited periods:
[RFC3448] does not distinguish between data-limited and
non-data-limited periods. "For Revised TFRC, this document distinguishes between
data-limited and not-data-limited periods." -> For Revised TFRC, this document distinguishes between
data-limited and non-data-limited periods. ------- C.3 "For a moderate data-limited period, Standard TCP would be limited by
X_recv from the most recent feedback packet. " -> For a moderate data-limited period, Standard TFRC would be limited by
X_recv from the most recent feedback packet. ------ C.4 " ...idle and data-limited periods, or with idle or
data-limited periods during Slow-Start," -> idle and data-limited periods, or with idle or
data-limited periods during Slow-Start. ------ C.5 "Work in progress such as Faster Restart [KFS07] can also decrease a application's incentive
to pad its sending rate," -> Work in progress such as Faster Restart [KFS07] can also decrease an application's incentive
to pad its sending rate, "Revised TFRC's response to data-limited periods is
less conservative that those of Congestion
Window Validation (and Standard TFRC's response to data-limited
periods was considerably more conservative that those of
Congestion Window Validation)." -> Revised TFRC's response to data-limited periods is less conservative than those of Congestion
Window Validation (and Standard TFRC's response to data-limited
periods was considerably more conservative than those of
Congestion Window Validation). Arjuna ------------------------------- Dr.Arjuna Sathiaseelan Electronics Research Group Email: arjuna@xxxxxxxxxxxxxx Web: www.erg.abdn.ac.uk/users/arjuna Phone : +44-1224-272780 |
