Abstract: A macro-switch is described. This macro-switch includes facing integrated circuits, one of which implements optical waveguides that convey optical signals, and the other which implements control logic, electrical switches and memory buffers at each of multiple switch sites. Moreover, the macro-switch has a fully connected topology between the switch sites. Furthermore, the memory buffers at each switch site provide packet buffering and congestion relief without causing undue scheduling/routing complexity. Consequently, the macro-switch can be scaled to an arbitrarily large switching matrix (i.e., an arbitrary number of switch sites and/or switching stages).
