We propose a novel optical switching system using fast time-slotted passive switching with shared OEO buffers. Simulation results show that the proposed system significantly reduces the blocking probability below 10 at a 28% cost of a traditional system due to flexibility of contention resolution using electrical buffer and potentially requires very low… (More)
We propose an Ethernet ring protection technique introducing a managed forwarding database scheme (FDB). The major benefit of the proposed FDB scheme is provisioning with a cost-optimized path that eliminates an unnecessary overprovision requirement.
Performance of optically transparent packet and burst switching is significantly improved by true buffers, even in a shared manner, rather than by wavelength converters in WDM OPS and OBS. A novel design rule is proposed, aiming at commercial feasibility.
