Systems and methods for profiling low latency applications using telemetry

A system comprising:

• a data processing system comprising one or more processors and memory, configured to:
• determine, using variability of data points of telemetry data received for a plurality of flows of packets, a variance of bandwidth, a variance of packet lengths, and a variance of inter-arrival times between packets for each of the plurality of flows of packets;
• generate, based at least on the variability of the data points of the telemetry data, a signature of a flow of packets of the plurality of flows of packets, the signature comprising a function computed using each of the variance of bandwidth, the variance of packet lengths, and the variance of inter-arrival times for the flow of packets;
• compare the signature of the flow of packets to a plurality of signatures of applications that are profiled;
• determine, based at least on the signature matching at least one of the plurality of signatures that comprises one or more variances of telemetry data that are at or below a variance threshold, a type of application for the flow of packets that supports maintaining a time interval between transmission and reception of packets for the flow of packets within a time threshold;
• and
• take, in response to determining the type of application, one or more actions to provide a quality of service for the flow of packets according to the type of application.
