             Description:
             Network operators all over the world are facing the
             same fundamental dilemma – traffic growth is
             outpacing their revenue growth. To avoid financial
             disaster they must lower the capital and operational
             costs associated with transporting bits, increase the
revenue derived from those bits, or some combination of the two.
To meet these needs, operators are entering a new phase of the
Sonet/SDH-to-packet network migration. It will require new
optical networking architectures and new technologies that must
achieve the following:

   • Improve transport costs
   • Accommodate existing services
   • Enable new services
   • Deliver operational simplicity
   • Provide deterministic performance and resilience
This new phase of evolution will yield innovations in optical
switching while more tightly coupling both transport and
switching. This white paper details the main shortcomings of
current optical networking architectures and the features and
functionality needed for the next-generation switching and
transport network.
