However, it is increasingly becoming the de facto solution when higher bandwidth
is required (even on legacy solutions) and for all new service offerings; this, along with
the development of a highly competitive landscape, continual technical improvements
and standardization, make the prospect of Carrier Ethernet dominating the future of
carrier services, a very distinct possibility??”it appears to be more a question of when
this will likely happen and not if it will happen. Market trends confirm this conclusion
as well. Chapter 3 and this chapter (16) highlight Carrier Ethernet??™s growth prospects
while Chapters 2 and 16 identify the challenges that it would face in this quest.
532 Appendix
Multiple Delivery Solutions Exist Today??¦
There is no one commercial solution that provides the entire gamut of Carrier Ethernet
capabilities today, at least economically; realistically though, there is still not an immediate
need for all these features in any substantial measure, and consequently, the
numerous (partial) solutions for Carrier Ethernet that have emerged are perfectly
acceptable. In fact, multiple commercial solutions exist because the different legacy
(pre-Carrier Ethernet) solutions, be it SONET or TDM or Copper, have also been augmented
with features to address the customer requirements for Carrier Ethernet (although
perhaps not optimally), and are eminently viable from an economic standpoint.
