A router, comprising: a core controller; a plurality of egress edge units coupled to said core controller, said plurality of egress edge units including at least one egress port; and a plurality of ingress edge units coupled to said core controller and in communication with said plurality of egress edge units, wherein each ingress edge unit comprises: a plurality of ingress ports; an ingress interface associated with each ingress port, each ingress interface operable to segregate incoming optical data into a plurality of subflows, wherein each subflow contains data intended for a particular destination port; and a TWDM multiplexer operable to: receive subflows; generate a micro lambda from each subflow; time multiplex each micro lambda according to a schedule pattern; wavelength multiplex each micro lambda; and transmit each micro lambda to a switch fabric according to the schedule pattern.

Port-to-port, non-blocking, scalable optical router architecture and method for routing optical traffic

One embodiment of the present invention includes a router comprising an ingress edge unit with one or more ports and an egress edge unit with one or more ports connected by a switch fabric. The ingress edge unit can receive optical data and convert the optical data into a plurality of micro lambdas. The ingress edge unit can convert the incoming data to micro lambdas by generating a series of short-term parallel data bursts across multiple wavelengths. The ingress edge unit can also wavelength division multiplex and time domain multiplex each micro lambda for transmission to the switch fabric in a particular order. The switch fabric can receive the plurality of micro lambdas and route the plurality of micro lambdas to the plurality of egress edge units in a non-blocking manner.

Embodiments of the present invention provide a system and method for routing optical data. In one embodiment of the present invention, data can routed in a non-blocking fashion from a plurality of the ingress edge units to a plurality of egress edge units by selectively connecting the ingress edge units to the egress edge units at a photonic core. Switching at the photonic core can be driven by a clock signal and does not require an electrical to optical conversion to occur at the core. This can allow switching on the nanosecond level, substantially faster than many prior art systems.

System and method of routing data at a photonic core

Systems and methods for optical cross connects which switch data at a container (packet) level. In one embodiment, a plurality of optical switch edges are coupled to an optical switch core via a minimal number of optical fibers. The switch core is configured to optically switch data from an ingress edge to one of a plurality of egress edges in a nonblocking fashion. The ingress edge receives data streams and distributes the data among a plurality of container processors. Each of these container processors produces an optical signal of a different wavelength, which can then be multiplexed with others to form a multiple-wavelength optical signal that is transmitted to the switch core. The switch core then switches successive portions (containers) of the multiple-wavelength signal to the egress edges to which they are respectively destined. The respective egress edges perform the reverse of this process to form output data signals.

Container based crossconnect

A system and method for providing non-blocking routing of optical data through a telecommunications router that allows full utilization of available capacity. The router includes a number of data links that carry optical data packets to and from an optical router. The optical router includes a number of ingress edge units coupled to an optical switch core coupled further to a number of egress edge units. The ingress edge units receive the optical data packets from the data links and aggregate the optical data packets into &ldquo;super packets&rdquo; where each super packet is to be routed to a particular destination egress edge unit. The super packets are sent from the ingress edge units to an optical switch fabric within the optical switch core that routes each super packet through the optical switch fabric to the super packet's particular destination egress edge unit in a non-blocking manner (i.e., without contention or data loss through the optical switch fabric). This routing is managed by a core controller that monitors flow information at each ingress edge unit to control the super packet generation and transmission to the optical switch fabric and schedules each super packet to exit the optical switch fabric so as to avoid contention among the plurality of super packets in the transmission between the optical switch fabric and the egress edge units. The egress edge units receive the super packets, de-aggregate the super packets into the original optical data packets, and transmit the optical data packets to the data lines.
