Abstract:
Systems and methods are disclosed for data communication by forming a hybrid that includes an electrical switching network with packet granularity of switching and store-and-forward forwarding services to network traffic and an optical switching network providing circuit granularity of switching and optical bypassing services to network traffic; applying local control of optical switching modules in the optical switching network with a network controller coupled to the electrical switching network, the optical switching network, and a loss-of-light detection module; and detecting loss-of-light in a failure point in the optical switching network and rerouting traffic to avoid the optical failure point.
