Switch elements, each receiving data from external sources and transmitting data to external sinks, are interconnected through a single rotator to form a switching node. The single rotator has a number of inlets equal to the number of switch elements and a number of outlets equal to the number of switch elements. A first set of channels connects the switch elements to inlets of the rotator and a second set of channels connects the outlets of the rotator to the switch elements. The connectivity pattern of the second set of channels is a transposition of the connectivity pattern of the first set of channels in order to preserve sequential data order of switched data. A controller communicatively coupled to the switch elements exchanges timing data with external nodes of a time-coherent network and schedules data transfer among the switch elements. |
