The upper bound on the minimum number of switching cells in crossbar switches was investigated. It was determined that the bound is given by N(N−1), where N is the switch size. Crossbar switches were embedded into ILLIAC(N, N−1) torus networks with cell counts given by the above formula and a simple routing control algorithm for the switches is introduced.

Inspec keywords: telecommunication control; switching networks; telecommunication network routing
