The Solutions Have Different Focuses Most solutions today are primarily focused
on bridging the chasm in metro access??”between the customer premise location and
the Service Provider??™s first Point Of Presence (POP). Several, however, are focused on
delivering Carrier Ethernet in the metro and beyond, in to the WAN. It must be noted
that realistically, even if a solution can be deployed across the metro and the core, it
is likely these solutions will be packaged in different commercial offerings (i.e., two
different models), each addressing a different segment. Differing price sensitivities in
the various segments make it unrealistic to have a one ???box??? solution across segments
(without being economically unattractive).
Carrier Ethernet Is Still Evolving and So Are the Solutions A fundamental challenge
to Carrier Ethernet solutions is that Carrier Ethernet is still very much in its
infancy and in the process of standardizing and evolving to support the next generation
of applications. Within such a dynamic context, the solutions are also invariably evolving
to align with these developments; albeit it must be noted that solution vendors, in
an attempt to competitively differentiate, often offer new features that may still not be
ratified by standards bodies.
