Title:
NETWORK CONFIGURATION ENUMERATION DEVICE, NETWORK CONFIGURATION ENUMERATION METHOD, AND NETWORK CONFIGURATION ENUMERATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/059378
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to propose a method for enumerating intermediate configurations at a high speed. A configuration enumeration device 10, upon acquisition of a smallest value C for the wiring capacity of mechanical patch panels having input layers 21, intermediate layers 22, and output layers 23, enumerates network configurations for the input layers 21, the intermediate layers 22, and the output layers 23 provided for the mechanical patch panels, the configurations minimizing the number of mechanical patch panels, using an α-quasi-nonblocking configuration where, with 0≤α≤1 being satisfied, when α=0, a rearrangeably nonblocking configuration is obtained and when α=1, a strictly nonblocking configuration is obtained.
