摘　　要：数据中心互联链路通信质量的准确评估是实现数网协同的重要基础。文章建立了基于波长选择开关的全光数据中心互联网络中的混合放大模型,可快速评估互联链路中的光信噪比与误码率等指标。文章讨论了无中继放大条件下的数据中心互联链路,给出了不同互联距离下的放大器选择方案,并通过仿真对比了在同等互联距离及光功率增益条件下,不同路径选择对互联链路通信质量的影响。根据相应的理论模型及算法,可建立数据中心互联网络的最佳路由。The accurate evaluation of the communication quality of the interconnection link of the data center is an important basis to realize the coordination in the data network.In this paper,a hybrid amplification model for all-optical data center interconnection networks based on wavelength selective switches is established,which can quickly evaluate indicators such as optical signal-to-noise ratio and bit error rate in the interconnected links.In this paper,the data center interconnection link under the condition of no repeater amplification is discussed.The amplifier selection schemes under different interconnection distances are given.Through the simulation,the influence of different path selection on the communication quality of the interconnection link is compared under the conditions of the same interconnection distance and optical power gain.According to the corresponding theoretical model and algorithm,the optimal routing of the data center Internet can be established.
