Re: [ns] Ns-users Digest, Vol 45, Issue 4
i have a problem the foloowing problem in NS2 (1) How to allocate buffer size (2) why is that +(Enqueue) and - (Dequeue) in trace files are sometime the same, when Enqueue means Arrival at the queue and Dequeue is departing , what is the reeason behind this? (3) How do i calculate Throughput and Jitter from the data in my trace file? (4) How do i calculate Loss rate from the information in my trace file. (5) how do i calcualte my sending time, because the trace file i got did not have sending time(s) what do i do? (6) can any one let me know how i can simply get the total (+), (-) , (r), in my trace file? thank you very much.

Re: [ns] printing the ackno
Hi, A one-way TCP does not use field ackno_. Instead, the TCP Sink creates an ACK packet by placing ACKNO in the field seqno_ of the ACK packet. So you just need to print out field seqno_ but you have to make sure that the corresponding packet is an ACK number. Cheers, Teerawat On 9/4/2007, Sebastian Harko [EMAIL PROTECTED] wrote: Hello, I want to print the acknowledgment number of every ACK in the terminal... So I went to tcp.cc ( newack method ) and I did this: cout ACK number is: tcph-ackno_ endl; but all the ACK numbers it prints for a simple simulation are equal to zero... note that i was able to print the correct sequence numbers using the exact same approach. what am i doing wrong ? regards
[ns] Wired cum Wireless routing using 802.11 snapshot.
Hi Everyone, I am doing research in the IEEE 802.11e hcca QoS enhancement using the ns2 802.11 snapshot ( ns-2-94a21377a8a6) by Mathieu Lacage. I was looking through the NS2 developers' mailing list and I saw that there was some attempts to implement Wired cum Wireless simulations using the 802.11 snapshot, and Franceso Gringoli from the University of Brescia mentioned that they had a script which they were going to try out. I have tried to adapt the model from Marc Greis' tutotrial but with nos succes. Does anyone have any tips or suggestions on this issue? Thanks very much in advance. Samuel Senkindu.

[ns] Relation between cwnd and rate?
I'm simulating CUBIC using TCP Linux and tracking cwnd and sending rate but the results are somewhat puzzling. I would expect the sending rate to equal cwnd * MSS / delay but it doesn't. It appears to be correct in itself (~90% of the link bandwidth), but the formula above suggest a rate about 3.5 times higher for all my experiments, with varying bandwidth, number of TCP flows and delay. What am I missing? -- Jasin
