I had the same problems in Ubuntu 6.10 and ns-2-31. I had to compile
with gcc and g++ 4.0 instead of 4.1 (default in my distro).
There are a couple of urls documenting this and how to install ns in

I do not know if carrying a bandwidth value inside the flow is the
best solution. Bandwidth as I see is data_transmitted/time. And time is
relative, are you going to measure the bandwidth in the last second, the
last minute, the last hour? So that why I think is not the best way. I
It would depend of what you want to do. I am using UDP and CBR in a
manual topology that I generated. There are some tools to automatic
generate a big number of nodes but I have not tested yet. Now my attacks
are confined to a small network.

I wonder if somebody has any documentation about rate-limit and
rate-limit-strategy. Both are under ns/pushback.
I have 69 nodes, it was working well until yesterday that I added one

You could get the rtt by c++ and by tcl. Tcl might be easier.
This is an example in tcl where $tcp0 is a tcp agent.
set rtt [$tcp0 set rtt_]

It would be great if you could share your experience in the wiki or in
a blog. I just could not make ns compile in eclipse.

I remember something similar with Frame Relay and mostly with ATM,

The original link is not working but you can use the google cache:
If you are working with your code in TCL may be you can make a map
Node_ID (from ns) to an IP address in your TCL script. If you are
working in C++ you can do what Sidney proposes.
Either way you have a way to do it, may be not trivial but definitely
Yes you can. You have to add the ns paths to eclipse. There is an old
e-mail with the references of the libraries to include and the paths.
Do a search in the list and you could find that e-mail.

You have to include your code (I am not sure but I think that you
should do it in the same path were the rest of the ns code is) and to
modify the make files in order to compile your code. Check the own ns
makefiles as an example, they will give you a hint of what to include.
Have you tried to install the BGP++ module in the latest version? May
be you would need to modify the make files and the ns-default TCL file
but it may be easier.
