re: Dr. Lawrence Roberts I'd place any amount of money I know exactly what Caspian is doing, and remember you heard it from "gea" first. Note that Daniel Blumenthal from UCSB has taken a leave to join Caspian.
What Caspian is going to try to do with optics is bascially the same thing that Ipsilon did with an ATM switch (converting a switch into a router by identifying switchable flows). With the Caspian switch, any time a flow is big enough to merit siwtching in the optical domain (ie, MEMs), then the electronic matrix will tag the flow and dump it down into the optical matrix.
In that sense, it is easy to scale to petabits, because once you have a wavelength flow, you've got 10Gb/s. Enough wavelength flows, and you're switching Petabits.

re: Dr. Lawrence Roberts What do people think of this statement?
"Roberts: I have a similar problem with it. And I have another problem. Once you successfully do photonic switching, itGÇÖs so cheap, where will [photonic switch manufacturers] get the revenue? LetGÇÖs just count the ports and how many there are going to be and what the market size is going to be. ItGÇÖs actually in the hundreds of millions at the best. "
The photonic switching companies carry hefty valuations based in large measure on perceived potential for exceptional revenue growth. Is the perception incorrect?-- will the revenue dry up because the market is smaller than thought?

re: Dr. Lawrence Roberts I agree with Roberts: There is little value add with core transport. There will be little intelligence in these boxes. Making the optical device to switch might be better, but actually moving the photons won't be a huge market.

re: Dr. Lawrence Roberts When I set out to read this interview, like other articles I am spending time with, what I was hoping for is what will make IP profitable? What keeps business owners up at night? The Internet? Does business find themselves lacking in bandwidth to accomplish their revenue goals with the internet? How much business is coming from the Internet anyway? What are the goals beside moving data and e-mail? Do they think they will be left out of the "New Economy" if they do not get a three demensional/fully interactive Web site? Isn't that what sales people are? What is the "New Economy"-Cisco thinks it is voice over IP. But then again, isn't that taking way the only considerable profitablility (economy) of a telecommunications/ISP? I guess the question boils down to, What markets are you creating with your products? Please do not tell me the "New Economy". Tell me your vision.
A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
