Correct... the sender is notified of the loss... you could

Hello everybody,
I'm running FreeBSD 6.2-RC1 GENERIC i386 on a lenovo 3000 v100 laptop which
has a Intel 3945 wireless device. I found the driver here
http://people.freebsd.org/~flz/local/wpi/wpi-freebsd-20061109.tgz
This driver was made by Damien Bergamini (merci enormement à lui)
I compiled
Thanks Randall.

Btw, TCP Urel is a option. To use it, you have to add something like,
int rc = setsockopt( inSettings->mSock, IPPROTO_TCP,TCP_URE, (char*)
&val, len );
to enable Urel option
Sveiki,
Yep, it was a problem at the upstream which was seeing the packets
twice and adding them into the pipe twice because of that. There were
no skipto rules at the upstream.

Michael,
In PR-SCTP where retranmission is set off, does it allows the
applications to know which part of data is lost in the stream?
Thanks
Yep.. you subscribe for a notification event and SCTP will
return you the data that was not sent.
So not only does it let you kno

It doesn't try to retransmit at all. A lost segment is lost and
resending it would be pointless for realtime content. On the other

Hi George,
Compare to SCTP, TCP Urel is much simpler. Drawback is the (1) lack of
multihoming, (2) directly implmentation of partial reliabiliity. These
drawbacks, however, allows more flexibility for usage.
hmm... I don't think I agree here :-)

Thank you Andre. You explain it clearer than me.
Yes, TCP's interweaving with retransmission scares people from
multimedia streaming point of view. So we find a way to remove
retransmission in TCP.
Acctually it turns out to be easier than it looks. We only add another
