network traffic and increasingly volatile traffic patterns are
causing significant economic challenges for service providers.
Current architectural approaches rely on network layers that are
built and operated independently. This model contributes to
scaling, provisioning, and operational inefficiencies that will
soon push service providers past the point where revenue can
keep pace with needed investments.  Technology advances within a
single network layer, although crucial, will not eliminate these
inefficiencies. An innovative new approach is needed that
softens and optimizes inter-layer boundaries to create a highly
converged transport architecture.  This converged transport
architecture must tightly integrate packet, optical time-
division multiplexing (TDM), an
