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.

This feature allows setting the desired maximum VOQ latency. Drop probabilities are adjusted in hardware to meet
