A transit memory assembly of a rotator-based switching node is logically partitioned into two sections, one operated as a common-memory switch fabric and the other as a time-shared space-switch fabric. The composition of data received at input ports of the switching node determines adaptive capacity division between the two sections. Based on an indication of traffic type, a controller of at least one input port selects one of the two sections. The space-switch section enables scalability to a high transport capacity while the common-memory section enables scalability to a high processing throughput. The switching node includes rotators and a bank of transit-memory devices that facilitate the incorporation of any mixture of periodic, aperiodic, contention-free exclusive-access, concurrent-access, and multicast switching.
