"Delivering Carrier Ethernet: Extending Ethernet Beyond the LAN"

In this section, I bring you some results
that highlight current service provider trends.
As service providers shift their focus from legacy services (ATM, Frame Relay, leased
lines) to ever-increasing optical and Ethernet traffic, they rely more heavily on new, innovative
technologies and face the challenge of maintaining and upgrading their optical

networks while defining and deploying new Ethernet services. In 2006, Infonetics published
Service Provider Plans for Metro Optical and Ethernet: North America, Europe,
and Asia Pacific 2006, a study conducted to determine the metro optical and Ethernet
equipment requirements and network implementation plans of service providers over
the next year. The study found that service providers are offering a surprising number
of network-based services over Ethernet, including voice, video, and storage. Ethernet
is used not only to collect and move Ethernet traffic, but also for IP and legacy services
and to move data among customers and POPs and COs.
Service Providers have now made considerable investments in Carrier Ethernet and
are considering what the most efficient approach for offering Ethernet services is.
