In a decade, the Ethernet has gone from being one among many LAN technologies to totally dominating, and then commoditizing onsite enterprise data networks. Now equipment vendors and service providers appear to be counting on Ethernet to work its cost-cutting and customer-attracting magic again, this time in carrier networks. The idea is partly a marketing bet on the power of the Ethernet brand to lure enterprise customers and carriers away from their legacy private line, frame relay and ATM WAN circuits, and partly an effort to retool carrier infrastructures. If Ethernet can do for carrier access and transport networks what it has done for enterprise LANs, the carriers should wind up with lower costs as well as simplified, customer-friendly service offerings. Customers will benefit by not having to deal with different network technologies in the wide area or throttle down their data traffic among sites. Enterprises with fiber access can get point-to- point and multipoint Ethernet links today in many metro areas.
