[LARTC] tcng and network processor

[LARTC] tcng and network processor

[Chris Clark]

I am considering a project to translate tcc output (C code or external
interface) to network processor code, so that the NP can do the actual
traffic shaping. I have a platform using the Intel IXP1200 NP on a PCI
card, which functions as a NIC for the host PC running Linux. This
approach would reduce the processing load on the host.

Has anyone attempted anything like this? 

I have never used tcng before, but I have been reading all of the
available documentation. Is there anything that I should know about tcc
or its output before I attempt this?

Thanks,
Chris

I see that Bivio uses a network processor with TCNG, but I can't find
any more details... There are no whitepapers on the website.

Werner (or anyone else at Bivio), are you able to provide any details?

As Jacob has pointed out, tcc's external interface is what
you're looking for.

It's about time somebody tackles the Intel NPs :-) Actually, it
would be good if - provided you get this project rolling - you
could find a way to get Intel to let you release your code
generator.
