Abstract (in Japanese) (See Japanese page) 
(in English) We are developing an optical layer-2 switch network (OL2SW-NW) that can efficiently aggregate traffic in a large-scale metro NW. The OL2SW-NW is based on WDM/TDM ring NWs of L WDM channels. This allows the bandwidth of wavelengths in the NW to be shared with m vs n logical paths between aggregation switches on the access NW and IP Edges on the core NW. The OL2SW-NW exchanges timeslot (TS) without buffers inside the network in terms of cost reduction. Therefore it is necessary to adjust the timing of the TS between each node in the OL2SW-NW. In this paper, we propose the method for synchronizing TS by using the control signal which is separated from data signals by applying the synchronization method of PON system to exchange TS between n vs m logical paths. We evaluate the accuracy of synchronization of timeslot by using a prototype system.
