Abstract: This paper introduces the implement methods of a high-speed optical interconnection network adapter for double token-ring network topology cluster. This network adapter is implemented based on FPGA technology and adopts high-speed high-bandwidth DDR DIMM bus as interface, optical fiber as network transmission media. Its routing protocols are implemented based on hardware logic embedded in FPGA chip. The network characteristics such as high-bandwidth, low-latency, high-reliability are ensured.
