Dear Ganesh,
I've tried to download your paper but I have received a 404 error by the
web server.

Best regards,

You will see more out-of-sequence packets than using the real
Internet. It is actually very straightforward to simulate (Max
theoretical) the condition using a simple C program to find the
maximum expected number of out-of-sequence packets. I had to face
this situation when using NIST Net for UDP transmission at 1000
packets/sec. You can use the FIFO patch to rectify it -- but remember
you will also be adding additional queuing delay and this will change
your distribution.
I have a paper on the performance results. You can download it here :

If you need the code to simulate, i can provide it to you as well.
Best,
Ganesh

Browsing of the mailing list archives is just available to mailing list
members.
The access is at http://www-x.antd.nist.gov/mailman/private/nistnet/
Search for a FIFO patch.
Hope this helps,
David

Thanks a lot
BTW: how to search previous emails? I just joined the mail list not long ago.
Thanks

Subject: Re: [nistnet] NISTnet mis-order packets
It's the expected behaviour. If the previous packet is randomly delayed
more time than the next, then there is a packet disorder.
I remember that somebody posted a patch to avoid packet disordering when
configuring a variable delay. Search the mailing list archives.
[EMAIL PROTECTED] escribi¨(R):
We are seeing when NISTnet running, packet misorder were seen after
adding jitter to traffic (delsigma not equal to zero )
The NISTnet version is 2.0.12b, anybody has any idea on that? Is it an
inherent problem of NISTnet implememetation.
Appreciates any inputs and help!
Thanks
Stephen
