具有旋转连接功能的双层光互连网络设计

在设计的双层光互连网络中,上层网络是星型连接,依靠数字路由结点进行通信.单通道最大传输速率为1.4 Gbps,数字路由结点吞吐率大于10 Gbps,底层为网络接口卡和结点机连成的环形网,峰值传输速率为1.056 Gbps.在底层网络中个别结点机与传感器之间配置有光纤旋转连接器,可传输动态数据.经计算,环网内最大通信延迟时间小于5.292 μs,互连网络的平均通信延迟时间为11.03 μs,环形网络的最大数据传输带宽为50 Mbit/s.

Design and Implementation of Two-layer Optical Interconnection Network with Rotating Connection

A two-layer parallel optical interconnection network has been designed. The top layer was a star network,which was made up of digital routing nod,node computer and optical network interface cards. The maximum transmission rate of single channel was 1. 4 Gbit/s and the total throughput of network was more than 10 Gbit/s with eight channels. The bottom layer was a ring comprising optical network interface cards and node computer. The peak transmission rate of optical interface cards was 1. 065 Gbit/s. Fiber optic rotary joints that can transmit dynamic data were assembled in sub layer network between the node computer and sensors. The maximum communication latency inside a ring was less than 5. 292 12s. The average communication latency of parallel optical interconnection network was 11.03/,s,and the bandwidth of the ring network was less than 50 Mbit/s.
