No wonder there is still so much transport using SONET. Using Ethernet reduces your effective performance over long distance paths.
The only reason to use (10)GE for transmission in WAN is the completely baroque price difference in interface pricing. With todays line rates, the components and complexity of a line card are pretty much equal between SDH and GE. There is no reason to overcharge for the better interface except because they (all vendors do this) can. We've just ordered a new WAN to be built, and we're going with GE over (mostly) WDM because the interface prices are like six times higher per megabit for SDH. (which would have cost roughly equally per line given that it is quite OK to run SDH without the SDH equipment, just using WDM) Oh, s/SDH/SONET/ on above, but I'm in Europe, so.. -- Måns Nilsson primary/secondary/besserwisser/machina MN-1334-RIPE +46 705 989668 If I am elected, the concrete barriers around the WHITE HOUSE will be replaced by tasteful foam replicas of ANN MARGARET!
