Photonic packet switch architecture based on multi-wavelength label switch

摘要

Label lookup (forwarding) speed of routers is main bottleneck in the current Internet. To construct node systems that improve the label lookup speed tremendously, we study photonic packet switches, where optical technology is fully used. In this paper, we address multi-wavelength label packet-based photonic network architecture that is more scalable than lightpath networks. We describe a high-throughput photonic packet switch, in which multi-wavelength label switches based on photonic label lookup and optical buffers based on electronic buffer management are internally used.
