ABSTRACT:
A scheduling apparatus for a switch includes multiple schedulers which are assigned in a variety of ways to non-intersecting control domains for establishing connections through the switch. The control domains are defined by spatial and temporal aspects. The control domains may be dynamically selected and assigned to schedulers in a manner that achieves a high throughput gain. Control domains may be considered in a cyclic and/or a pipeline discipline for accommodating connection requests. The invention enables the realization of a highly scalable controller of a switching node of fine granularity that scales to capacities of the order of hundreds of terabits per second.
