Yes I have heard of barefoot, but have you heard of barefoot queuing architecture or pre-classifier granularity and queuing strategy or packet size based pps performance graph, well yeah neither did I.

Well there are use cases for fancy asics and use cases for simple asics.

Yup and those are dirt cheap compared to their home grown asics , this is because for a given pps rate they have lot less smarts.

Well I guess that could be a story of some of the smaller shops that can't afford investing in R&D and thus rely on well-trodden paths, but certainly not my problem.

I understand your passion for open sw and open hw architecture, but routing high pps rates on x86 will always be impractical compared to specialized asics.
Yes going x86 certainly makes sense for low pps use cases - a uCPE is a good example of such a use case.
And as far as the high pps rate use cases goes, reading other posts in this thread, it seems that the current state of the art with regards to any linux OS driving any white-box ASICs is not quite ready for primetime yet.
A viable alternative might be the FPGA NICs -but seems still not financially attractive.
Just wondering what's the latest on the GPU for packet forwarding front (or is that deemed legacy now)?
