摘　　要：针对三维有源光网络路径配置时间长、光路由器插入损耗大和网络硬件开销高等问题,文章设计了自适应路由算法和无阻塞、低损耗光路由器。自适应路由算法利用XYZ确定路由算法进行端口的初次判断,再根据端口阻塞情况进行二次判断,最终选择无阻塞和距离短的端口作为节点输出端口;针对三维通信需求分别设计层内6端口和层间3端口光路由器代替7端口光路由器。实验结果表明,利用自适应路由算法进行路由计算时,路径建立过程延迟小、阻塞低,光路由器所需波导和微环谐振器数量少、插入损耗低,平均插入损耗仅为0.88 dB,光网络硬件开销低。In order to solve the problems of three-dimensional active optical network,such as long path configuration time,high insertion loss of optical router and high network hardware overhead,this paper designs adaptive routing algorithm and non-blocking,low-loss optical router.The adaptive routing algorithm uses the XYZ determines the routing algorithm to make the first judgment of the port.Then it make a second judgment according to the blocking condition,and finally choose the non-blocking and short distance port as the node output port.Optical routers with 6 ports in the layer and 3 ports in the layer are designed to replace optical routers with 7 ports for three-dimensional communication.The experimental results show that when the adaptive routing algorithm is used for routing calculation,the delay of path establishment is small and the blocking is low.The number of waveguides and micro-ring resonators required by optical routers is small,and the insertion loss is small.The average insertion loss is only 0.88 dB and the optical network hardware has low overhead.
