Re: AT&T's Open ROADMs
Absolutely fascinating, this sounds like the future in telecommunications!  It appears to be the next evolution of technology - along the lines of software-defined networks, virtualization, etc. 

Looking forward to the Radio Show.

Re: AT&T's Open ROADMs
I agree...as someone who started out in telecom by covering optical switching, I am looking forward to hearing Andre talk about ROADM.

As luck would have it, Alison over on the New IP has posted a very good Q&A with Andre

He has been busy. Alison had some questions I hadn't thought of, so a good primer for next week.

Re: AT&T's Open ROADMs
@Mike, thanks for the heads up.  That is good additional information.

I particularly like the points made on open ROADMs and open standards.  I look forward to hearing more about that in the Radio Show.

Re: AT&T's Open ROADMs
@NewIPLiz, I will be very interested in your comments after the presentation - with your background in optical switching!  Particularly your perspective on how much change this truly represents.

Re: AT&T's Open ROADMs
I had a SONET flashback while reading both Andre stories.

AT&T looks to be solidly on the train of history, but did they get on board too soon?
Proprietary/closed systems, methods, and formats have a very short lifetime, historically; all the advantages are with being able to use the larger net and the greater number of connections, and almost every successful technology goes more and more open on its way to becoming more and more standard. Once that transition happens, it's very self-enforcing: The standard may or may not be the best possible standard, but the best results are usually gotten by using the standard.

So AT&T is moving fast in the direction of the inevitable, and that's a good direction to move in general.

The interesting question is whether AT&T is making the move too soon (at the risk that someone else will pull off standardization around some other version of reconfigural optical multiplexers) or just in time (advantage of being first on the field and having others have to catch up with you).  But for sure, they're not making it too late, and better to take the occasional light hit from going too early (hello Apple) than the brutal wallop from going too late (insert names of a thousand defunct companies here).

Oh the possibilities
It is amazing what the possibilities might be when more telecom becomes open, rather than being bogged down by specific providers. The idea of not having to worry about how much traffic is  on the network when you're online is almost revolutionary. I can't wait to see what Fuetsch has to say on the radio show, and see just how long we will have to wait before this becomes a reality.
