An architecture for facilitating wavelength-specific and packet-switched
routing comprises a primary metropolitan fiber ring, a primary
distribution/aggregation node in the primary metropolitan fiber ring and
a local service domain further comprising a secondary aggregation node in
communication with the primary distribution/aggregation node. A network
to provide local metropolitan switching and routing and broadband local
access distribution described in terms of its component layers comprises
a distribution/aggregation routing layer that interfaces with a primary
fiber metropolitan ring and a local customer primary
distribution/aggregation node via transport branches of a mesh
architecture, a local distribution and routing layer that routes specific
wavelengths and newly assigned wavelengths to and from a customer's
premises and a cross-connect layer that handles customer specific
wavelength and packet routing via one of fiber, millimeter wave radio and
free space optical communications.
