<br>
The FairDrop queue we have implemented to drive our tests with
DCTP simply drops packet of the most opportunistic flows in the
queue. Meaning that if you have 3 flows and a full queue of 30
packets, you should have 10 packets of each flow enqueued.

Three flows. <br>
<br>
Manu, how do you want to implement fair queueing on a backbone
router with actually 200.000 flows? 150.000 of them being "mice"?<br>
<br>
At least this question should be discussed for both kind of
approaches, VJCC and DTCP. <br>
<br>
So to my understanding, neither VJCC nor DTCP separates the problem
of resource allocation from the problem of congestion control, nor
do they eventually <i>solve</i> the problem of (fair) resource
allocation.<br>
<br>
To my understanding, many of us recognize the problem of a missing
(convincing) resource allocation scheme here and replacing VJCC by a
scheme which runs into the same difficulties as VJCC is a bit
beating about the bush.<br>
