TDM hypercube and TWDM mesh optical interconnections

Proposes the time division multiplexed hypercube (TDM-cube) and the time/wavelength division multiplexed mesh (TWDM-mesh). The TDM-cube is an extension of the earlier work by Thompson (1991) on the dilated slipped banyan network, DSB. The TDM-cube(N) implements the binary hypercube interconnection among N nodes in log/sub 2/N time slots. The TWDM-mesh(n/sup 2/) uses a DSB(n) and combines the TDM and WDM. Both the TDM-cube and TWDM-mesh require only one fixed-wavelength transmitter and one fixed-wavelength receiver per node, and have a simple column control and a dilated operation. The performance in terms of channel efficiency, delay and throughput is analyzed.
