Maybe some clarification as to what you're asking for would help.  You're mixing fiber, networks, and a MAN.  Fiber is just the medium.  It could be for IP switching or projecting a light show.  Are you asking if there are diverse paths throughout a metro area?

Hello folks,

Simple question: does "routed optical networks" have a clear meaning in the metro area context, or not?

Put differently: does it call to mind a well-defined stack of technologies in the control and data planes of metro-area networks?

I'm asking because I'm having some thoughts about the clarity of this term, in the process of carrying out a qualitative survey of the results of the metro-area networks survey.

Cheers,

Etienne
