confusion about metro ethernet
Can someone provide explanation please.
As i understand metro ethernet is just a MAN moving away from standard sonet/sdh layer 1 transport technology to ethernet based solution.
The most advanced form is using IP/MPLS in core to allow services such as L3 VPN.
However, I don't see this portrayed as WAN technology. Can this very same technology suit be used for large WAN distances? I guess I'm missing a point here in a difference between the two!

I think Metro Ethernet is usually a service offered in large cities where there is a lot of dark fiber available for use. MPLS Ethernet or VPLS is more of a WAN technology and I don't see why it couldnt be used for a Metro ethernet deployment?

Ok, I know about those links;
the confusion arises because the Metro Ethernet is not necessarily just Ethernet deployment in MAN, the way I see it; ISPs can offer Ethernet as WAN service, in addition with IP/MPLS in their core, to replace things like DS1 and Frame Relay;
So Metro Ethernet would be anything outside enterprise LAN... Does Sonet/SDH seem like a necessity for very long distances fiber or is Ethernet ultimately getting out as a winner?
What exactly is boundary of Metro Ethernet!?
Can anyone more knowledgeable wrap this topic up a bit?
Thx
