Abstract	This paper presents a nonblocking routing algorithm for Beneš networks. Such networks are of potential interestin implementing large scale optical cross-connects, but theircomplex routing algorithm limits their applications. We use asimple approach to determine the routing tags for a conflictfree routing. Available methods proposed in the literature usecomputationally complex solutions to determine the routing tags.We propose a new approach for determining the paths throughthe network for all the requests coming to the inputs of the switchfor unicast routing. Each switching stage has been represented bya set of sub-matrices and hence a conflict free routing is found.The correctness of the generated routing tags have been validatedwith mathematical method as well as with a simulator thatcan validate the correctness of the routing tags. This algorithmrequires less complex practical implementation than the loopingalgorithm, making it viable for use in cross connect systems.
