Abstract (in Japanese) (See Japanese page) 
(in English) In order to perform an optical network which offers various services for future applications in metro area, this paper proposes a hybrid optical ring network architecture combing two forwarding paradigms, optical circuit switching (OCS) and multi-wavelength optical packet switching (MW-OPS).
Nowadays, ring networks adapting reconfigurable optical add/drop multiplexer (ROADM) technology based on OCS are widely used in metro area. Although it can provide QoS-guranteed communication, ROADM has the drawback of low bandwidth utilization due to the nature of circuit switching. On the other hand, while recently appeared ring burst technologies based on optical burst switching technology can provide high bandwidth utilization, very high accuracy for time slot allocation is needed to provide QoS-guaranteed communication.
In this paper, we propose a hybrid ring network architecture combining OCS and MW-OPS to utilize the merits of the both two forwarding paradigms. We design a hybrid switching node and preliminarily demonstrate the switching node in 120 ($12\lambda\times 10$) Gb/s testbed.
