Summation and routing on a partitioned optical passive stars network with large group size

摘要

In a partitioned optical passive stars (POPS) network, n=dg processors are divided into g groups of d processors each, and such a POPS network is denoted by POPS(d,g). There is an optical passive star (OPS) coupler between every pair of groups. Hence, a POPS(d,g) requires g/sup 2/ couplers. It is likely that, in a practical system, the number of couplers will be less than the number of processors, i.e., d
