Evolution of Solutions Delivering Carrier Ethernet
Over the longer run, especially as the market matures, it is reasonable to assume that
the solutions will evolve in the manner illustrated in Figure 16.8. The key points of
this evolution are
?– Multiple solutions for Carrier Ethernet will continue to be actively deployed over the
next several years, but it is likely that the number of such solutions will be reduced.
Evolution of Carrier Ethernet Solutions 529
?– As the overall trend to packet-based applications continues to accelerate and
voice applications (the mainstay of the many legacy solutions) are also migrating
to packet infrastructure, Service Providers will increasingly find the prospect
of maintaining legacy networks less attractive.
?– As competition intensifies and price pressure correspondingly increases, Service
Providers will have to move to more economically efficient infrastructures to
protect profitability.
?– The solutions that will coexist will do so for a variety of reasons, most notably
because there is no silver bullet, i.e., no single solution that addresses the multitude
of real-life deployment scenarios economically.
