queue discipline...............


hello,

accordi[/B]ng to my knowledge the working of linux queue
is as below .Can u please tell me is it right......

( I traced pkt traversal from dev_queue_xmit( ) in linux2.4.**/net/core/dev.c till
hard_start_xmit( ) linux2.4.**/ net/sched/sch_generic.h)

here it goes

dev_queue_xmit( ) -> takes an skb and

calls q->enqueue( ) .

After pkt is enqueued dev_queue_xmit( ) calls
qdisc_run( )

Which inturn calls qdisc_restart( )

here the pkt is dequeued (q->dequeue( ))

and finally pkt is sent to device with the

hard_start_xmit( )................

Now my doubts r,
->are the above steps repeated for each single pkt or
do they work on 'n' number of pkts?


-> How many pkts are queued at once( ie in the dev_queue_xmit( ) )?
is it just 1 or more.

Thanks ,
SHRI
