1. A method comprising:
identifying a fingerprint for traffic flow over a communication network from an application executing on a device to a multi-access edge (MEC) server instance hosted by a MEC platform, wherein the fingerprint is identified based upon source communication information used by the application and destination communication information of the MEC server instance;
utilizing the fingerprint to track the traffic flow between the application and the MEC server instance during runtime of the application for measuring round trip time latencies of the traffic flow;
in response to a round trip time latency of the traffic flow from the device to the MEC platform violating a latency management policy during a timespan, measuring segment latencies along segments of a communication travel path of the traffic flow from the device to the MEC platform during the timespan;
performing a management resolution function based upon one or more of the segment latencies exceeding a threshold; and
performing a reactive diagnostic latency test to determine if performance of the management resolution function resolved the violation.
