Latency and drop information help determine if there is a loss in a particular flow and where the loss occurred. A Service Node action configured as a DANZ Monitoring Fabric (DMF) managed service has multiple separate taps or spans in the production network and can measure the latency of a flow traversing through any pair of these points. It can also detect packet drops between any two points in the network if the packet only appears on one point within a specified time frame, currently set to 100ms.
