Josh, thank you, your remarks (and those of Matt and Eduard) are helping me to understand better. For some context, please look at this graphic <https://drive.google.com/open?id=1HkXAbd2PIQF_ACOeQYDtpeGxTEaTT1Y7&authuser=etienne.depasquale%40um.edu.mt&usp=drive_fs> that shows the results of the question "Which of the following best describes your current dominant form of metro-aggregation?" The left bar chart shows *NOG reponses; the right bar chart shows responses obtained through market research among Tier 1 and regional operators. Operator group respondents overwhelmingly selected "routed optical networks over Ethernet without ROADMs". Now, during an interview I held to assess the answers, the interviewee (an experienced network engineer) questioned the meaning. I realized that I may have been conditioned by Cisco marketing (I attend a few webinars), and I wanted to understand what respondents understood. Summarizing an answer to your observation, I was conditioned by Cisco marketing. Cheers, Etienne On Mon, May 1, 2023 at 10:30 PM Josh Luthman <josh@imaginenetworksllc.com> wrote:
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
