Customers are moving to FTTH and cable, or going WiMAX and Metro-Ethernet. Ethernet seems to have taken an even bigger bite out of DS-3. The bigger pipes seem to favor ethernet. A recent upgrade from OC-3 to GigE transport actually saved us a large chunk of money. I'm wondering if others are seeing the same behavior, if it's market-dependant, or if I'm just imagining things. I'm working on building new infrastructure and my current thoughts are to minimize my TDM footprint. It would be useful to get a better feel if this is an overall trend or something local.Why I think it comes down to is do you want to use frame-relay, atm, sdh and ethernet when you can just use ethernet? lan-phy ethernet has economies of scale that result in lower cost along virtually every dimension relative to the alternatives.Thoughts?
