摘要
基于深度学习的光网络流量诊断与预测等场景中,由于保密等原因,光链路的流量数据采集和存储工作受限。针对数据量少而无法支撑深度学习的问题,文章提出了一种基于拓扑链路识别的光网络流量数据合成算法,其核心思想是在生成对抗网络框架下,联合基于光网络拓扑的条件生成模型和基于光网络流量的数据合成模型,以自监督的方式合成指定光链路的流量数据。仿真结果表明,所提算法合成的光网络流量数据在自相关系数指标上与真实数据接近且使得基于全连接神经网络的流量预测模型准确率达到95%以上。
In the scenarios of traffic diagnostic analysis and prediction in optical network based on deep learning,the work of traffic data collection and storage for optical link is limited due to security and other reasons.Aiming at the problem that the amount of traffic data is too small to support deep learning training,this paper proposes an optical network traffic data synthesis algorithm based on topology link recognition.The core idea is to combine the conditional generation model based on optical network topology and the data synthesis model based on optical network traffic in the framework of generative adversarial networks.The traffic data of the given optical link is synthesized in a self-supervised way.The simulation results show that the auto-correlation coefficients of the traffic data synthesized by the proposed algorithm is close to the real data,and the accuracy of the traffic prediction model based on fully connected neural network is more than 95%.
