“…Eng and Acampora [11] further related a time-and-space division multiplexing problem for terrestrial switching systems for finding sequences The three-stage Clos network [7] is a fundamental switch of switching matrices for satellite-switched time division architecture for providing a connection between any pair multiple access networks; some subsequent work may be of input and output terminals. This basic architecture has found in [2,4,5,29,[35][36][37]. been successively generalized [20,33,34,38] to provide Varma and Chalasani [38] studied the routing of multimultiple simultaneous connections between sets of input connections in a rearrangeable three-stage Clos network.…”
