System for switching data using dynamic scheduling
ActiveUS7218637B1Lower latencyImprove performanceData switching by path configurationTime scheduleData interchange
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.

A transmitter directed, distributed receiver using multi-user diversity provided by the distribution of the receiver. Advantage is taken of the uncorrelated variations over time in the condition of communication links between a common transmitter and several users. The greater the variation in the quality of a particular link over time, the greater the increase in total system throughput provided. A scheduler metric (or scheduler metric) represents the instantaneous quality of the communication link between each user and the transmitter with respect to the average quality of the link. Alternatively, the scheduler metric represents the instantaneous channel condition with respect to the average data throughput over that channel. The common transmitting station uses the scheduler metric to directly compare the desirability of granting each channel access with the desirability of granting each other channel access. The users with links that have the greatest scheduler metric are provided access to the channels.
