Abstract
Systems and methods for optical switching of time-varying traffic, including generating fixed-length bursts using one or more Optical Edge Nodes (OENs). The bursts are temporarily stored in electrical buffers located at the OENs, wherein the electrical buffers include one or more burst queues, and one burst queue is allocated for each of one or more destination OENs. The OENs are interconnected using one or more Optical Switching Nodes (OSNs). A control protocol is implemented to establish and remove soft reservations using at least one of the OENs and OSNs, optical channels are reserved for a duration long enough to transmit one or more data bursts, the duration being selected independently for each of the one or more burst queues, the control protocol gives precedence to avoiding disrupting of any existing soft reservations when reserving resources; and the soft reservations are capable of being reused until overridden.
