摘　　要：光纤网络数据动态能力较强,受噪声的影响,易降低数据的分配效率。为此,提出一种新的多通道数据均衡化分配方法。在建立通信模型后,计算节点的负载占比变化,并均衡处理待分配数据节点的负载占比。然后建立传输过程的连续表达函数,并通过最小均方差的约束,保证分配代价的合理性。最后,计算在同时间间隔内数据载波带宽的变化分配相同带宽变化的数据。实验结果表明:应用该方法后,数据分配结果的归一化幅度保持在±0.6之间,不同类型的数据分布规整;该方法的分配误差集中在2.59%~3.51%之间,具有较高的精准度。The data dynamic ability of optical fiber network is strong,and it is easy to reduce the data distribution efficiency due to the influence of noise.Therefore,a new multi-channel data equalization allocation method is pro-posed.After the communication model is established,the load ratio of the compute nodes changes,and the load ratio of the data nodes to be allocated is balanced.Then the continuous expression function of the transmission process is es-tablished,and the rationality of the allocation cost is guaranteed by the constraint of the minimum mean square error.Finally,the data with the same bandwidth change allocated by the change of data carrier bandwidth in the same time interval is calculated.The experimental results show that the normalized range of data distribution results is within±0.6,and the distribution of different types of data is regular;The distribution error of this method is concentrated in 2.59%-3.51%,with high accuracy.
