Re: Cooperation pays off
Venders already did, last month Huawei announced that they delivery the first SDN optical network for one of china opeator in south-east part of china, it seems the first commercial launch.

Re: Cooperation pays off
Sterling,

In the context of SDN, you've used the term transport network to refer to the optical network. Now I could be wrong, but it seems to me that "transport" is a relative term: E.g. If Ethernet services are being used to move around IP packets, then isn't the Ethernet service/network itself the transport network. And if, as is typically the case, Ethernet frames/services are being delivered over xWDM channels, in that case the optical network is serving as the transport network. So the point I'm making is that the transport network can be at Layer 2(Ethernet) or at the optical layer. If I'm correct, then the term transport SDN should not be exclusively applied to the optical network.

Carol, exactly, these are the types of proof points that will be needed.

Sterling,

Might the demos be used to determine which approach makes the most sense?

Re: Cooperation pays off
I agree, the OIF and the ONF are a good combination to tackle transport SDN. As we discussed at BTE, one of the big challanges for transport is the analog and proprietary nature of optical transmission - which is something that is not going to change, possibly ever. There seems to be momentum for an intermediary controller that would translate between OpenFlow and the proprietary gear beneath it.

Beyond that though, there also is alot of momentum behind a host of IETF protocols that seem to be eating away at the role of OpenFlow in transport. I think the ONF and OIF have work to do to prove that OpenFlow with extensions is the best solution.

Re: Cooperation pays off
I think it does, Dan. There are definite issues that have to be addressed, but this is a significant step in the direction of addressing them.

Re: Cooperation pays off
Does this signal more openness to OpenFlow among carriers and their vendors? For a while, many of them have been skeptical, and I got the impression during a couple panels at BTE that might still be the case.

So many companies are in both groups -this makes sense on many fronts and could work to speed up the process of bringing SDN to the optical world.
