<DIV><FONT size=2> Hi, </FONT><FONT size=2>while implementing a
streaming server, I am currently doing TFRC transport adaptation
module.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>After reviewing several papers of Sally Floyd and A.
Zakhor, I sill cannot implement it just because</FONT></DIV>
<DIV><FONT size=2>I cannot understand one thing:</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>"How to calculate Round-trip time in Receiver?"</FONT></DIV>
<DIV><FONT size=2>--------------------------------------------</FONT></DIV>
<DIV><FONT size=2>it is written in her paper how to get Roud Trip time in
Sender, measuing the feedback for same sequence num.</FONT></DIV>
<DIV><FONT size=2>(now my quetion, when the Rx decide to reply it?)</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I need this value because </FONT></DIV>
<DIV><FONT size=2>"Rx should report feedback to the sender at least once per
round-trip time if it has received packets in that interval"</FONT></DIV>
<DIV><FONT size=2>(page 3 of SIGCOM 2000 publication, Equation-based
Congestion control for Unicast Application, Sally Floyd et al).</FONT></DIV>
<DIV><FONT size=2>I checked it from D. Tan and A. Zakhor papers in IEEE
multimedia, but the mechanism is not clear.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Maybe I can check with Sally's ns-2 simulation script, but it
is too much her computer-setting dependent script.</FONT></DIV>
<DIV><FONT size=2>I think it is not a big problem on their work, but I just want
to know how they implemented it.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Thanks.</FONT></DIV>
