<DIV><FONT face=Arial size=2>We have updated the TCP Westwood+ linux kernel
implementation with the<BR>two following changes:<BR><BR>o RTT_min is updated
each time a timeout event occurs (in order to<BR> cope with hard handovers
in wireless scenarios)<BR><BR>o The bandwidth estimate filter is now initialized
with the first<BR>bandwidth sample in order to have better performances in the
case of<BR>small file transfers.<BR><BR>The patch has been applied to the
mainstream kernel and it will be<BR>available for kernels >=
2.6.18.<BR><BR>The patch is available at:<BR><BR> <A

in<BR>order to enable the logging of the "end to end bandwidth estimate"
variable used by westwood+.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I remember for sake of completeness that
the only diffrence between westwood and westwood+ is the "bandwidth estimate"
algorithm that in westwood+ provides a measure of used bandwdith that is not
aliased.</FONT></DIV>
