Re: Same old, same old
With the products due to ship tomorrow, I don't think there's much wiggle room.

If they ship it one time, that helps, too. I think there were some folks out there betting that after annoucement last fall, Cisco was going to change its plans or push out its schedule, but no such luck.

Re: Same old, same old
Cisco is betting that customers will value Cisco more than they want to separate the control and forwarding plane. It's a good bet.

Re: Same old, same old
There is no separation of control/ forwarding plane - both are on the switch. The APIC pushes policies (network profiles) to the switch and translation into concrete configs for switch control/forwarding plane happens locally. A declarative model.

One of the big boys (Google) is using the same approach for Container VMs in GCE.

Re: Same Old, Same Old
@sammasud, it certainly offers an "inhibited" SDN at a minimum.  I fully agree, it is a self-serving version.  But, as you and Mitch comment, they probably have the market standing to pull their version off as long as they provide excellent service.

There is, however, the opportunity for someone to truly develop SDN solutions that demonstrate the full capabilities that Cisco is not using.  It will be interesting to watch.

If APIC pushes polices out to the switches, then it seems to me this is not a separation of the control/forwarding planes. Seems like while the big boys, Facebook, Amazon, etc., have one vision for building networks, Cisco's response is to continue protecting its turf the old-fashioned way. Cisco has the money and time to get on the bandwagon, but old habits are proving hard to break.

Still, it won't matter whether Cisco fully embraces SDN--provided it can offer a solution that has better capex/opex than what SDN promises to deliver.
