摘要： The present invention provides a system and method for slot deflection routing of optical data packets. The method of the present invention includes the steps of establishing a schedule pattern that includes a plurality of time slots. The schedule pattern includes at least one time slot in which an ingress edge unit can communicate with a destination egress edge unit, at least one time slot in which the ingress edge unit can communicate with a intermediate edge unit, and at least one time slot in which the intermediate edge unit can communicate with the destination egress edge unit. The present invention also includes receiving a data packet at the ingress edge unit and determining if the schedule pattern allocates sufficient bandwidth to send the data packet from the ingress edge unit to the destination egress edge unit without deflecting the data packet through an intermediate edge unit. If enough bandwidth has been allocated, the data packet can be sent to the destination edge unit from the ingress edge unit without deflection. Alternatively, if enough bandwidth has not been allocated, the data packet can be deflected to an intermediate edge unit prior to being communicated to the destination egress edge unit.

摘要： Embodiments of the present invention provide a system and method for providing non-blocking routing of optical data through an optical switch fabric. The optical switch fabric can include an optical switching matrix with a plurality of inputs intersecting with a plurality of outputs. A path switch can be located at each intersection that is operable to switch data arriving on an input to a particular output. The path switches can be configurable to create a plurality of unique paths through the optical switching matrix to allow routing in a non-blocking manner. Another aspect of the present invention can provide a system and method for providing non-blocking routing through an optical cross-bar switch. The optical cross-bar switch includes a plurality of input links, a plurality of output links and a plurality of switching elements. Each switching element can include a plurality of path switches connecting each of the input links to at least one of the output links and the plurality of switching elements can be configured to create a plurality of unique paths through the optical cross-bar switch.

摘要： A non-blocking optical matrix core switching method that includes maintaining a schedule for routing data through an optical matrix core and receiving and analyzing reports from peripheral devices. The method determines whether the schedule is adequate for the current data traffic patterns and if the schedule is not adequate a new schedule is implemented. The new schedule is then transferred to the peripheral devices for implementation and the new schedule is transferred to the optical matrix core scheduler. Implementation of the new schedule as the schedule on the peripheral devices and the optical matrix core scheduler is then performed.

摘要： Methods and systems for dynamically computing a schedule defining interconnections between ports in a switching system. In one embodiment, a switching core requests demand reports from the ingress ports. In response to this request, the ingress ports generate a series of suggested port schedules, beginning with a first choice, then a second choice, and so on. The schedules are transmitted to the switching core, beginning with the first choice. The switching core receives the first choice for each of the ports and determines whether the aggregate schedule defined by the first choices is valid. If the aggregate schedule is valid, then this schedule is implemented. If the aggregate schedule is not valid, portions of it are discarded and the next choice from each of the ports is examined to identify connections to replace the discarded portions. This process is repeated until a valid schedule is obtained.
