This paper provides an integrated monitoring and analysis method for SDN-VPN. This method establishes a consistent process to monitor the status of SDN-VPN network elements (NE), and integrates the alarm and health information of NE for alarm correlation and service impact analysis. The maintenance personnel can monitor the status of all NEs with a single panel. The proposed consistent process consists of multiple parts, including the mechanism of collecting NE alarms and resource status from Resource Orchestrator (RO), alarm correlation analysis, and service impact analysis. With the process, we can learn the cause of the fault events in SDN-VPN, the nature of the fault, and the scope of service impact, thus accelerating trouble shooting and improving service quality.
