Abstract: A network monitoring system compares gathered network information with path information. The comparison between gathered network information and path information provides traceability of automatic and dynamic rerouting function of network and makes it possible to understand the relation between root cause and observed problems. The combined monitoring of data plane with control plane enables identification of the original failure point where behavior is changing though routing failure is propagated around. This will allow the identification of network issues that may lead to service outages and impairments as well as alerting of issues affecting customer satisfaction, and is effective to reduce MTTD (Mean Time To Detect)/MTTR (Mean Time To Repair) and increase service availability in all markets.
