Re: R: [ns] queue limit

[Ganesh <ggopalak@lucent.com>]

Hi,

If every node has a Traffice source  ( like a CBR or FTP source etc..)
and a Agent like TCP or UDP etc..where exactly is this queue u are
talking about ?? Between CBR source and TCP ?? If so, shouldnt it be
ideally very large ?? ( Please correct me if I have worngly understood
the scenario u guys are referring to )

I have a question regd this..

1) Can I modify the queue limits or is it fixed ?? Does it vary with each
type of traffic source or each Agent ??
2) How do I know a packet was dropped because it overflowed the sender
queue ?

Thanks,

Ganesh
