1. Apparatus for facilitating establishment of connections in a switch fabric having a plurality of input ports and a plurality of output ports in response to a succession of connection requests received from said plurality of input ports, said apparatus comprising: multiple schedulers, operating concurrently and independently, and cyclically associated with non-intersecting control domains defined by non-intersecting sub-frames of a repetitive time frame, each scheduler operative to accommodate a connection request within a control domain with which said each scheduler is associated; a plurality of domain-state memory devices each holding occupancy states of all input ports of said plurality of input ports and all output ports of said plurality of output ports during a respective sub-frame from among said non-intersecting sub-frames; and a request distributor for distributing said succession of connection requests to said schedulers.
