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.

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： An architecture and related systems for improving the performance of non-blocking data switching systems. In one embodiment, a switching system includes an optical switching core coupled to a plurality of edge units, each of which has a set of ingress ports and a set of egress ports. The switching system also contains a scheduler that maintains two non-blocking data transfer schedules, only one of which is active at a time. Data is transferred through the switching system according to the active schedule. The scheduler monitors the sufficiency of data transferred according to the active schedule and, if the currently active schedule is insufficient, the scheduler recomputes the alternate schedule based on demand data received from the edges/ports and activates the alternate schedule. A timing mechanism is employed to ensure that the changeover to the alternate schedule is essentially simultaneous among the components of the system.

摘要： A method for implementing an activity based resource assignment medium access control (MAC) protocol to allocate resources to subscribers in an interactive, multimedia, broadband satellite communications system. A plurality of channels is provided with at least one of said plurality of channels being assigned to each of a plurality of terminals. Utilization of the channel resources by the plurality of terminals is monitored and an evaluation is conducted of system needs based on the levels of activity and utilization of channel resources by the terminals. Requests for system resources by the terminals are communicated to a resource controller which calculates the system needs. The resource controller is utilized to adjust the channel resources based on the levels of activity and utilization of resources by the terminals. The adjustment provides active terminals as much resources as required during duration of their activity, subject to resource availability.
