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.
