An FPGA-based Node Controller for a High Capacity WDM Optical Packet Network

We present architecture and experimental results for an highspeed digital node controller developed in the “RINGO” project, a demonstrator of a next-generation ultra-high capacityn etwork based on WDM optical fiber ring. The MAC protocol and other controller functions have been developed on a high capacityF PGA, which supports efficient input queuing and multicast capabilities byh andling several concurrent real time processes.
