<DIV><FONT face=Arial size=2> The paper "performance evaluation and
comparison of westwood+, Newreno and vegas tcp" we published in ACM CCR, april
04 issue contains some experience that could be considered. In
particular:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><FONT face="Times New Roman" size=3>1. one single
forward connection and on-off-on-off reverse traffic in order to test the effect
of reverses traffic (f.i. one reverse TCP of the same
flavour)</FONT></FONT></DIV>
<DIV><FONT face=Arial size=2><FONT face="Times New Roman"
size=3></FONT></FONT> </DIV>
<DIV><FONT face=Arial size=2><FONT face="Times New Roman" size=3>this scenario
is to test the effect of reverse traffic that is VERY important becasue it
affects the ack flow of the forward TCP connection</DIV>
<DIV><BR>2. single bottleneck</DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>the sequence number versus time of different
connections show how fair is the advancement of each connection. this graph can
show strong unfairness and starvation</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV>3. multi bottleneck. this case is quite complex . under high load our
experience is that all TCPs performance slow down. </DIV>
