    A novel optical switch architecture comprising internal ring-like fiber interconnections is presented and discussed in this paper. The architecture allows optical packet and burst switching as well as multicasting directly in the optical domain by copying and forwarding of packets and bursts without wavelength conversion. We expect a reduction of packet/burst discard probability due to the ability... View full abstract»
