I'm new to this list ... I hope that I've understood the scope correctly.

I'm looking for reference implementations of IP/MPLS operator networks within ***the metro area***, that do not abstract the underlay (underlying transport).

To clarify, I would like to see the underlying multiplexing technology, whether it's wavelengths, OTN, statistical using long-reach Ethernet (e.g. 10GBASE-ER), SONET/SDH.

Can anyone suggest a pointer?

Sincerely,

Etienne
