Network path health scoring based on load binned latency data

A non-transitory, machine-readable medium having program code stored thereon, the program code comprising instructions to:

• determine observed additional latencies with respect to a base latency of a network path based on time-series latency data of the network path;
• determine circuit load of each of a plurality of time intervals of the time-series latency data based, at least in part, on both ingress and egress loads;
• bin the observed additional latencies into corresponding ones of a plurality of load bins based, at least in part, on the determined circuit loads;
• determine an observed additional latency average for each of the plurality of load bins;
• determine an average of the observed additional latency averages of at least a subset of the plurality of load bins;
• determine an average of expected additional latencies of the subset of the load bins;
• and
• score health of the network path based, at least in part, on the average of the observed additional latency averages and the average of expected additional latencies.

An apparatus comprising:

• a processor;
• and
• a machine-readable medium having instructions stored thereon that are executable by the processor to cause the apparatus to,
• determine observed additional latencies with respect to a base latency of a network path based on time-series latency data of the network path;
• determine circuit load of each of a plurality of time intervals of the time-series latency data based, at least in part, on both ingress and egress loads;
• bin the observed additional latencies into corresponding ones of a plurality of load bins based, at least in part, on the determined circuit loads;
• determine an observed additional latency average for each of the plurality of load bins;
• determine an average of the observed additional latency averages of at least a subset of the plurality of load bins;
• determine an average of expected additional latencies of the subset of the load bins;
• and
• score health of the network path based, at least in part, on the average of the observed additional latency averages and the average of expected additional latencies.
