A new optical transport layer also will emerge, Infonetics believes. This new layer will be a fused Ethernet-WDM packet transport with circuit-like capabilities via Ethernet transport tunnels, also known as COE, or connection oriented Ethernet. That means more adoption of T-MPLS and PBT, Infonetics believes.
There was a time when some argued that "connectionless" protocols such as IP would replace "connection oriented" protocols such as time division multiplex, SONET and asynchronous transfer mode. As it turns out, there's a reason why connection-oriented protocols, or at least protocols that emulate connections, are important. Some traffic types, especially video and voice, are susceptible to impairments that can arise when connectionless protocols are used.

Ethernet Keeps Growing
Ethernet continues to gain a more prominent role in networking capabilities being deployed by service providers in North America, Europe, and Asia Pacific, with most carriers reporting 90 to 100 percent increases in Ethernet traffic for the past two years, according to analysts at Infonetics Research. IP and MPLS traffic has grown 70 to 80 percent over the same period, Infonetics says.
