The development of optical fibres combined with the advent of wavelength division multiplexing have enabled enormous growth of transport capacity in fibre based networks. Network nodes, such as switches and routers, deploy electronic solutions and have become a bottleneck of the Internet. In order to overcome the switching problem, optical solutions are developed, but components to enable switching in optical domain are lacking. Therefore, solutions that utilise both optical and electronic domain have been proposed. In this presentation, background for optical switching is introduced and the most promising optical switching concepts are surveyed. Finally, foreseen directions of optical switching are reviewed.
