A new logical topology based on barrel shifter network over an all optical network

This paper presents a new logical topology SBS-net, a scalable barrel shifter network to be used as a logical topology over an all-optical network using WDM. The major emphasis of the present work is to improve upon the scalability issue. This SBS-net connects any arbitrary numbers of nodes as opposed to the barrel shifter, de Bruijn graph and Shufflenet. The average hopping distance between two nodes using this topology is smaller compared to that in de Bruijn graph, Shufflenet & GEM net.
