Design of an OTN-based Failure/Alarm Propagation Simulator

Abstract

This thesis presents OTN failure/alarm propagation behavior analysis and an OTN simulator based on failure/alarm propagation behavior on the optical layer of optical transport network (OTN) architecture. The simulator code is implemented by Python. The failure, alarm, and propagation behavior examples discover from the Huawei Optix OSN 8800/6800/3800 V100R009C10 reference book [HW]. The simulator is used to restore the basic failure/alarm propagation behavior and generates valuable results, including alarm, alarm flow, the ground truth matrix of alarm flow, and the active alarm flow dependency graph. The results are the ground truth data for future applications such as root cause analysis and restoring hidden propagation behaviors.
