Fair Queueing

[Taroon Mandhana <mandhana@research.bell-labs.com>]

Hi,

 I am using FQ in ns. What I could understand, for FQ by default, in the
link, the head_ points to a FQ classifier_ which has pointers to various
DropTail queues_ (corresponding to each flow) and each of these DropTail
queues_ point to a FQ object(which maintains the finish tags etc etc). So
when an enque happens on one of the flows(it happens on one of the
DropTail queues), it checks for the qlim_(on the droptail queue for that
flow)  to decide about dropping. But, this qlim_ is seperate for each flow
queue.

 I am trying to simulate a router with fixed number of buffers, hence I
want to impose qlim_ for global queue and not individual flows. Is that
feature already available in ns?? 

Thanks,
Taroon
