Switch and select topology for photonic switch fabrics and a method and system for forming same

摘要

A method for generating a switch fabric topology, comprising constructing a first switch fabric topology, modifying the first switch fabric topology to generate a second switch fabric topology, wherein modifying the first switch fabric topology comprises isolating center stage sets of the first switch fabric topology, and replacing each of the isolated center stage sets with a single × switching element to generate the second switch fabric topology, wherein is an integer representing a radix of the switching element determined in connection with the constructing of the first switch fabric topology.

1. A computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:
constructing a first switch fabric topology; and modifying the first switch fabric topology to generate a second switch fabric topology, wherein modifying the first switch fabric topology comprises:
isolating center stage sets of the first switch fabric topology; andreplacing each of the isolated center stage sets with a single × switching element to generate the second switch fabric topology; wherein is an integer representing a radix of the switching element determined in connection with the constructing of the first switch fabric topology; wherein each isolated center-stage set comprises 1× switching elements in a final stage of a plurality of input-port trees and ×1 switching elements in a first stage of a plurality of output-port trees; and wherein the 1× switching elements are connected with the ×1 switching elements by 2 waveguides.
