In reply to Randy.

First let me make a comment on my blog, that I mention in places but maybe needs more emphasis. In this blog I am giving you my interpretation and observations from this conference, and only from this conference (with in some cases some additional external data points).

So for example in this case - OpenFlow on optical - I'm not suggesting there is a general industry movement on OpenFlow in optical networks, I'll be honest I don't know if there is or not! I am just reporting what I heard at the conference, and to be honest I heard more about OpenFlow on optical networks than any other type of network, so it made me question the likelihood of widespread adoption of OpenFlow to SDN across e.g. IP networks!!

At the conference, there was a detailed technical presentation on OpenFlow in optical networks, and one of the carriers at the conference separately talked with interest on OpenFlow. The presentation was from a university lecturer, it was an academic research proiject as I understand and to be honest I didn't pick up whether there were plans to implement such a scheme in production optical devices.
