and completeness of delay data in delay-sensitive application scenarios
it is necessary to implement end-to-end service delay estimation in Optical Transport Networks (OTN).
【Methods】
2
This paper first analyzes the transmission characteristics of OTN services
and collects service routing information according to the sub-net connections. Next
it discretizes the basic data such as Network Elements (NE)
links
and cross-connection in service route. Then the characteristic variables for delay estimation are obtained. Finally
the paper proposes a delay estimation model based on engineering live network
and compares the simulation results of various machine learning algorithms.
【Results】
2
The Mean Absolute Percentage Errors (MAPE) of the delay estimation results based on Support Vector Regression (SVR) and decision tree regression were 3.362 8% and 1.284 9%
respectively.
【Conclusion】
2
The OTN service delay estimation method based on machine learning and the characteristic of OTN transmission in this paper has high accuracy and wide application scenarios.
