1) High Speed Networks - Optical Networks


- Hybrid Optical Switching and Power Consumption in Optical Networks

New applications and services are driving the demand for new high-speed transmission technologies. Wavelength division multiplexing (WDM) is able to provide the required capacity by dividing the available bandwidth into different wavelength channels, each able to support up to 100 Gbps. Several switching paradigms have been proposed for WDM networks: optical circuit switching (OCS), optical burst switching (OBS) and optical packet switching (OPS). OCS is well suited for large and stable traffic flows but it is highly inefficient in presence of bursty sources. OBS perform efficiently both in case of constant and bursty sources, but introduces high losses at the core nodes. Finally, OPS provides high bandwidth utilization but requires a large optical buffering capacity at the core nodes which is very difficult to provide. In order to combine the advantages of all the three proposed technologies, a hybrid optical switching (HOS) approach has been recently proposed. In a HOS network, large flows are transmitted using circuits or long bursts while small flows are transmitted using packets or short bursts.
