Equipment manufacturers have,
of course, also recognized this opportunity and, in fact, are providing numerous carrierclass
solutions to deliver Carrier Ethernet. (Chapters 1 and 2 provide some insight into
the evolution of Carrier Ethernet from its LAN origins to a formidable Service Provider
solution while Chapter 3 presents its market proliferation). Carrier Ethernet services
are incorporating new feature capabilities required to support the next-generation of
applications and are quickly being standardized (also noted in Chapter 2).
??¦But It??™s a Long Way to Domination
Notwithstanding Carrier Ethernet??™s very impressive growth, it is still, in relative terms,
addressing only a minor portion of the total addressable opportunity. At the current
time, it is largely supplanting existing substitutes such as ATM but still has a long way
to go to overtake solutions such as Frame Relay and Private Line. And while it is capable
of enabling sophisticated, real-time multimedia applications on a large scale, it is
currently being used to mostly offer simple applications (such as Internet access, LAN
interconnection, Ethernet Private Line, and to a much lesser extent Layer 2 VPNs).
