Ethernet increasingly is viewed as the replacement technology for outdated SONET/SDH metro and huge area networks, and considered by many to be the global transport solution for packet-based traffic going forward. But to displace SONET/SDH, Ethernet must be more than economical; it must be truly high performance and easily interoperable with existing support systems. This high-performance Ethernet is, in fact, available today, and being deployed by service providers, enterprises and government agencies worldwide. It's called Carrier Ethernet.
