Abstract:
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.
