Introduction to Metro Ethernet ServicesWhat is Metro Ethernet ?• “… generally defined as the network that bridges or connectsgeographically separated enterprise LANs while also connecting across theWAN or backbone networks that are generally owned by service providers.The Metro Ethernet Networks provide connectivity services across Metrogeography utilising Ethernet as the core protocol and enabling broadbandapplications”from “Metro Ethernet Networks – A Technical Overview” from the Metro Ethernet ForumSLIDE 8COPYRIGHT © 2012 ALCATEL-LUCENT.
