Design of optical burst switches based on dual shuffle-exchange network

In this paper, we propose a multistage switch architecture for optical burst switching based on dual shuffle-exchange network (DSN). DSN is a deflection, self-routing network which exerts small penalty on each deflection. Its operational simplicity and bufferless nature are highly preferable in the optical environment. It can also be showed that this architecture is able to achieve high throughput even with blocking internal modules.
