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.
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 10-6 at a 28% cost of a traditional system due to flexibility of contention resolution using electrical buffer and potentially requires very low… (More)
