RHiNET-2/SW是一种网络交换机，可在分布式环境中实现基于高性能光网络的并行计算系统。在这样的计算系统中使用的交换机必须提供具有高可靠性的高速、低延迟分组交换。我们的交换机允许高速8 Gb/s/端口光数据传输，传输距离可达100米，总吞吐量为64 Gb/s。在RHiNET-2/SW中，8对800 Mb/s/spl倍/12通道光互连模块和单芯片CMOS ASIC开关LSI（784引脚BGA封装）安装在一个紧凑的板上。为了实现高性能并行计算，该交换机必须提供高速、高可靠的节点到节点数据传输。为了评估交换机的可靠性，我们测量了数据通道之间的误码率（BER）和偏斜。在800 MB/s /spl times/10 B的数据速率下，通过一个I/O端口的信号传输的BER优于10/sup-11/，具有大的定时预算裕度（870 ps）和小于140 ps的偏斜。这表明RHiNET-2/SW可以在基于网络的并行计算系统的节点之间提供高吞吐量、高可靠性的光数据传输。
RHiNET-2/SW is a network switch that enables high-performance optical network based parallel computing system in a distributed environment. The switch used in such a computing system must provide high-speed, low-latency packet switching with high reliability. Our switch allows high-speed 8-Gb/s/port optical data transmission over a distance of up to 100 m, and the aggregate throughput is 64 Gb/s. In RHiNET-2/SW, eight pairs of 800-Mb/s/spl times/12-channel optical interconnection modules and a one-chip CMOS ASIC switch LSI (a 784-pin BGA package) are mounted on a single compact board. To enable high-performance parallel computing, this switch must provide high-speed, highly reliable node-to-node data transmission. To evaluate the reliability of the switch, we measured the bit error rate (BER) and skew between the data channels. The BER of the signal transmission through one I/O port was better than 10/sup -11/ at a data rate of 800 Mb/s /spl times/10 b with a large timing-budget margin (870 ps) and skew of less than 140 ps. This shows that RHiNET-2/SW can provide high-throughput, highly reliable optical data transmission between the nodes of a network-based parallel computing system.
