too slow, in the sense for connections that usually never get out of slow start
and are latency sensitive need something faster. Proposals; second is nto really
a customer complaint per-se but not good behavior in general, which is that
slow start doubles rate before it hits a loss and this overshooting of buffer
should be avoided if we can detect it. <o:p></o:p></span></p>

Slow Start.<br>
The first discussion is about the scope of the SSDT group. A good starting
point is to list what people have experienced as incovenient behavior of slow
start. Once we agree on what to address, we can scope the objectives/goals of
the SSDT group.<o:p></o:p></span></p>

Subject: Re: [Iccrg] "Slow Start" design team<br>
<br>
Greetings Michael and Lars,<br>
<br>
An advantage of separate mailing lists is that it allows people set up<br>
filters for the mail clients. That could also be done by asking<br>
people to put a keyword in their email subjects (like slowstartDT).<br>
<br>
FWIW, I'm unlikely to subscribe to the DT mailing lists, but wouldn't<br>
mind extra traffic on iccrg@...<br>
<br>
Cheers,<br>
Lachlan<br>
