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] cbr packet loss & or packet count scripts in perl>>>>
Plz see the following awk scripts that calcualate the following
Performance Metrics Used
Routing Overhead
Normalize Routing Load
Packet Delivery Fraction
Average End to End delay
Jitter
Drop Packets
Drop Bytes

These scripts work with new trace format and DSR protocol. Make changes for
other protocols.

awk -f throughput.awk output.tr

[ns] a question about Nils-Erik Mattsson's DCCP module
I'm using Mattsson's DCCP module under ns-2.26. But when I simulate DCCP in large BDP networks, I sometimes get the following error and the program exits: DCCPAckVector::sendAckVector - Failed to add ack vector to option: err -1, size 256 I took a look at the source code and found that the error stems from the length of the options exceeding DCCP_OPT_MAX_LENGTH(=255 by default). So I set the macro to be 1023, hoping that would solve the problem. But when I run the simulation again after modifying the macro, I get some other errors: 21.610164, DCCP/TCPlike(_o216)::send_packetRecv() - No ack vector on acknowledgment! 21.610184, DCCP/TCPlike(_o216)::processOption() - ECN check failed! The only change I made to the source code is just setting the value of the macro bigger. I don't know what's wrong. Can anyone help me? _ 用 Live Search 搜尽天下资讯！ http://www.live.com/?searchOnly=true
