[ns] Queue Behavior

[Lee <yli@gpu.srv.ualberta.ca>]

Hi all,

I got confused by the queue bahavior as follows.

queue  delayed  lost
  50  0.000000 0.031301
 100  0.027464 0.031114
 250  0.132526 0.030552
 500  0.133060 0.029616
1000  0.134127 0.027739
2000  0.134621 0.026927
4000  0.134621 0.026927
12000 0.134621 0.026927
The first column is queue size,
I set it by, Queue set limit_ 1000
(Instead of $ns queue-limit n1 n2 limit for all the links)
Second column is the delayed packet the receiver agent observes.
Third column, lost packet.

I guess the first two rows are incorrect since the receiver
agent could not see all the packets, before they get lost in the network.

For the next 6 rows I am confused.
The buffer size becomes much larger,
however the percent of lost packets varies a little.

Would you like to give me some clue,
why the queue behaves like above?

Thanks so much!
Lee
