This
ultimately translates into lower CAPital EXpenditures (CAPEX), lower OPerational
EXpenditures (OPEX), and competitive positioning for Service Providers. Thus, Carrier
Ethernet helps realize the compelling benefits to both end users and Service Providers
as detailed in the Chapter 1.
Defining the attributes of Carrier Ethernet in greater detail and refining them further
to be more relevant for next-generation applications is an ongoing effort; considerable
progress has, however, been made.
54 Chapter 2
Enabling Carrier Ethernet
Carrier Ethernet is increasingly being adopted by the Service Provider and enterprise
end??“user community not only as the default access solution (i.e., service connectivity is
via Carrier Ethernet), but also one that is being employed end-to-end across the WAN.
Service Provider networks are, in fact, evolving to deliver the consistent Carrier-class
Ethernet services end users are coming to expect. Chapter 3 highlights the growing
demand for Carrier Ethernet services worldwide.
Carrier Ethernet is, however, still a work in progress; in fact, it is still in its infancy
and being more formally defined, refined, and continually augmented based on learning
from real??“life field deployments supporting emerging applications.
