Rearrangeable nonblocking minimal spanning switch

Rearrangeable nonblocking minimal spanning switch

I am trying to build a larger crosspoint switch from smaller ones as found
here http://en.wikipedia.org/wiki/Nonblocking_minimal_spanning_switch
They refer to a clos network. I try to simulate the configuration of the
switches in java but dont know how to rearrange the middle stage so that
it is not blocking. I found a paper about how to implement but I have a
hard time understanding the permutation matrix calculations. Is there an
implementation in Java already or somebody has a clue how to implement the
paper
