[Ns-developers] GSOC application requesting information

[Ali Ahmed]

I have going over the information provided thus far and am trying to chalk
out the steps needed to port the Linux network stack to ns-3 simulator .
I am new to kernel development in general and would like to ask about the
scope of the project .

I am unclear on what comprises the network stack in linux .

A starting point would be the essential things like  net/core --  skbuff.c

along with  the assortment of headers like

netdevice.h , skbuff.h etc .

Form here on in where does the stack extend to .

All the way to routing cache and table ?

I know I may be a bit vague , but  could someone provide some insight  on
what is required for this project.

We did exchange a few emails recently about this:
http://mailman.isi.edu/pipermail/ns-developers/2008-March/003815.html

which has links to the nsc project which did something similar. nsc was
in fact half-ported to ns-3 a couple of months ago:

The target is really the latest kernels.
