LINUX IP Stack

LINUX IP Stack

[Ram Shankar]

We are interested in moving the IP stack into the
application area. i.e. It should link with our
application and use the devices (like /dev/eth0) for
the layer 2 interface.

Regarding this we have following questions

1. How feasible it will be to move the IP stack from
the kernel to the application level. Note we would
leave one copy of the IP stack in the kernel. But for
the interfaces we are interested in we want the IP
stack to be at the application layer.

If this is feasible, what would be procedure to be
followed?

2. Is there any documentation available for the linux
IP stack and all its interfaces (highest level calls
provided, interfaces to layer2 devices, interfaces to
other kernel services etc.)?

3. Is there any other free implementation of IP stack,
which would be better suited for this purpose?

Thanks,

Ram

Have a look at the arsenic project:
http://www.cl.cam.ac.uk/Research/SRG/netos/arsenic/

They've already done it. ;-)

I don't know, wether these meet your requirements, but Google
lists several:
