摘要
设计一个具有旋转连接功能的双层并行光互连网络.顶层为数字路由结点(DRN)和光网络接口卡(ONIC)组成的星型网,吞吐率大于10 Gbps;底层为ONIC连接而成的环形网,峰值传输速率1.056 Gbps.光纤旋转连接器(FORJ)的引入增加了网络的灵活性和使用范围.该网络的最大吞吐速率为8.448 Gbps;环网内平均延迟2 195 ns,环网间平均延迟4 713 ns;误码率小于10-14;结点机之间的链路长度最大可达5.46 km.
Abstract
A two-layer parallel optical interconnection network with rotary joint function was designed. The top layer is a star network with throughput more than 10 Gbps made up of a digital routing node(DRN) and optical network interface cards (ONIC); while the bottom layers are ring networks made up of ONIC with peak transmission rate of 1. 056 Gbps. The application of fiber optic rotary joint(FORJ) expands the flexibility and using range of the network. The peak throughput of the network is 8. 448 Gbps. The average transmission delay time of and between the rings is 2 195 ns and 4 713 ns, respectively. Bit-error rate is (BER) below 10-11.The maximal link distance between node computers is 5.46 km.
