摘要： A wavelength routing SW is a large-scale optical switch device of a conventional technique, and it requires as many wavelength-tunable light sources as the number of input ports. For the wavelength-tunable light sources to achieve a stable oscillating operation across a wide wavelength range, a complicated control mechanism is necessary. This has been an obstacle in providing a large-scale optical switch device in terms of cost and circuit scale. A wavelength routing SW in the present disclosure includes N wavelength group generators, a splitting-selection unit, and MN tunable filters. Each wavelength group generator includes M fixed-wavelength light sources. Inexpensive general-purpose devices that require no control mechanism for wavelength tuning can be used as the fixed-wavelength light source. The channel loss in the optical switch device can also be reduced by using light sources with a limited narrow range of tunable wavelengths and the wavelength-dependent output port selecting function of an AWG.

摘要： A network switching system and method and a computer program product for operating a network switch are disclosed. The network switch includes a multitude of input ports and a multitude of output ports. In one embodiment, one processing device is assigned to each of the input ports and output ports to process data packets received at the input ports and transferred to the output ports. In one embodiment, the method comprises creating an intermediate adjustable configuration of processing devices functionally between the input ports and the output ports, and assigning the processing devices of the intermediate configuration to forward the data packets from the input ports to the output ports to obtain a balance between latency and synchronization of the transfer of the data packets from the input ports to the output ports. In an embodiment, software is used to create and to adjust dynamically the intermediate configuration.

摘要： A photonic frame switching system may include a main controller and at least one photonic frame wrapper line card. The main controller may determine a point in time at which a photonic frame wrapper line card transmits a photonic frame by allocating a time slot to the photonic frame wrapper line card. When the photonic frame switching system includes a plurality of photonic frame wrapper line cards, points in times at which the plurality of photonic frame wrapper line cards transmits the photonic frames may be synchronized. In particular, when a portion of the plurality of photonic frame wrapper line cards transmit a plurality of photonic frames having different destinations, points in times at to which all of the plurality of photonic frame wrapper line cards transmits the photonic frames may be adjusted based on a latency by a destination change.

摘要： Hybrid dilated Benes photonic switching architectures employ an arrangement of two-by-one (2×1) photonic and two-by-two (2×2) photonic elements to enjoy improved cross-talk performance while maintaining moderate cell counts. A jumpsuit switch optical network node architecture comprising multiple stages may operate more efficiently than single stage switching fabrics, by enabling manipulation of connectivity in some stages to achieve load balancing over other stages. Specifically, a first stage of switching fabrics connected to input ports of the optical node may be manipulated to load balance incoming signals over a second stage of switching fabrics coupled to output ports of the optical node. Additionally, a third stage of switching fabrics connected to add ports of the optical node may be manipulated to load balance added optical signals over the second stage of switching fabrics.
