Intel talks about the their Fulcrum silicon (FM6000) fully supporting OpenFlow. If one of the bigger merchant silicon vendors is shipping OpenFlow ready silicon, then I would expect new products to arrive in the next few months. I believe Intel is demoing this at Interop.
We’ve also contributed our Barcelona 10GbE TOR switch reference platform for an SDN demo that is part of the Interop Labs (iLabs). The demo shows how Barcelona performs when it is controlled by an OpenFlow software control plane.
