I agree with other saying that you cannot avoid timeouts in general.
At best, you can reduce them..<br>
In any case, you can check <br>

<br>
But the best source is: ;)<br>

``Passive analysis of TCP anomalies'', Computer Networks, Vol.52,

[algorithm implemented in tstat, and results are available online :)]<br>

then<br>
- select polito/LIVE as trace<br>
- tcp::stats -> total number of anomalies<br>
Note that the algorithm has been fine tuned to 2007 TCP... so today
it may need some refinement..<br>
<br>
We also did some work on how to reduce the number of RTOs<br>

Hi.
<br>
<br>
Are there some papers out there comparing how often TCP congestion
is detected by timeout and how often it is detected by triple
duplicate ack?
<br>
<br>
I'm basically interested, whether timeouts could be overcome
completely or whether there will be a permanent need for a working
timeout scheme in TCP.
<br>
<br>
Thanks.
<br>
<br>
