Hi,
I want to drop the packet on the basis of aging of the queue.
Aging is the time for which packet can reside in the queue.If packet
remains in the queue more than aging time then we have to drop the
packet.
For this i have added a field in the skb structure lets say qInTime
which will be updated at the time of enqueing to the queue with the time
of enqueue.We can calculate the aging time (time of dequeue -
skb->qInTime) while dequeing the packet.Depending on the
configured/custom aging of queue we have to drop the packet.I have added
field aging in Qdisc structure for aging.
I have added code for dropping packet in the dequeue function of the
queue (RED and FIFO) used on the basis of aging time.Ideally the number
of packets going in to htb tree is equal to the number of packets coming
out from htb tree.As we are consuming (dropping) packets in the htb tree
of traffic control so it is showing warning as "pfifo qdisc 300: is
non-work-conserving?".
Please suggest the way/place for dropping packet on the basis of
aging.Please help me ASAP.
Have you looked at "codel" or "fq_codel" in the more recent kernels?
The COntrolled DELay algorithm/heuristic does something that sounds
rather like what you are looking for, albeit with a couple tweaks.

I did check in codel but did not find any way.Can any one suggest here ?
