Re: Flow based architecture in data centers(more specifically Telco Clouds)

They don't have to be related. 🙂

I am curious about the distinction about the flow versus non-flow architecture for data centers and I am also 
fascinated by the separate issue of WAN architecture for these clouds.

Regards,

Roderick.

(caution, I'm just a chemical engineer, but)

You appear to ask one question: "What is the difference between flow
and non-flow architectures?"
then sideline in some discussion about fiber/waves vs
layer-3/transit/peering/x-connect

I don't think the second part really relates to the first part of your message.
(I didn't put this content in-line because .. it's mostly trying to
clarify what you are asking Rod"
