激光的发散角很小,光束质量直接影响通信的可靠性和速率,导致增量大数据冗余,存在激光通信网络链路剩余负载率较低,丢包率较大的问题。由此提出了基于大数据分析的激光通信网络数据传输最佳路径选择方法。首先基于大数据分析技术计算激光通信网络的光束质量增量,结合光束质量优化代价、链路传输效率、链路剩余负载率和链路带宽建立路由决策函数,并根据决策函数得到激光通信网络路由的最优路径,最后进行了性能测试实验。结果表明,本方法可以描述激光通信网络路由变化特点,链路丢包率小,激光通信网络数据传输效率高,并且提高了激光通信网络利用率。

The divergence angle of laser is very small,and the beam quality directly affects the reliability and speed of communication,leading to redundancy of incremental big data.There is a problem of low residual load rate and high packet loss rate in laser communication network links.A method for selecting the optimal path for data transmission in laser communication networks based on big data analysis is proposed.Firstly,based on big data analysis technology,the beam quality increment of the laser communication network is calculated,and a routing decision function is established by combining the beam quality optimization cost,link transmission efficiency,link remaining load rate,and link bandwidth.Based on the decision function,the optimal path for laser communication network routing is obtained.Finally,performance testing experiments are conducted.The results indicate that the proposed method can describe the characteristics of routing changes in laser communication networks,with low link packet loss rate,high data transmission efficiency,and improved utilization of laser communication networks.
