Abstract

In recent years, the amount of traffic in the Internet has doubled annually. To address this rapid demand, all-optical networks have gathered interest and attention in the research community. In this talk, I will give an overview of all-optical network architecture and introduce a breakthrough technology from NTT Laboratories called the Hikari Router. The Hikari Router is a GMPLS -based photonic multilayer router consisting of cost-effective multilayer (IP and optical layers) signaling and routing techniques. I will also discuss another recent research work on a cost-effective all-optical network architecture for metropolitan area network (MAN). This new architecture is a single-hop WDM network based on central arrayed waveguide grating (AWG) and it has an autonomic collision avoidance mechanism in couplers between the AWG and network nodes.

Dr. Noriaki Kamiyama received his M.E. and Ph.D. degrees in Communications Engineering from Osaka University, Japan, in 1994 and 1996, respectively. From 1996 to 1997, he was a visiting researcher at the University of Southern California, USA . In 1997, he joined NTT Multimedia Networks Laboratories as a research scientist. He has been active and engaged in network research areas focusing on IP networks, content-distribution systems, optical networks, and Internet measurement.
