IFQ drops problem in ns2.35
I have my own routing protocol, which has been built using ns2.35 and Ubuntu 14.04. Previously, I used to run an 80 seconds simulation for 10 flows of CBR packets (0.2 interval) over UDP with 54Mbps data rate.The PDR value collected from an awk file was perfect with no drops at all. Currently, I'm running a 30 seconds simulation for 9 flows of CBR packets (0.01 interval) over UDP with 24Mbps data rate, but it gives me a bad PDR value that sometimes reaches 2% because of the many IFQ drops in the trace file despite the successful sending of the AGT packets. Increasing the ifq length or the queue of the protocol itself does not make any changes.
Any idea about the problem I'm facing knowing that the ARP has already been disabled?
