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 DMF-managed service that, given two separate taps or spans in the production network, can measure the latency of a flow traversing through these two points. It can also detect packet drops between two points in the network if the packet only appears on one point within a specified time frame, currently set to 100ms.

The DMF Application Identification feature allows monitoring of applications identified from packets taken from filter interfaces and sent through the fabric by sending IPFIX reports to a collector. The feature provides a filtering function by forwarding or dropping packets from specific applications before sending the packet to the analysis tools.
