Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. An apparatus, comprising:
one or more network interfaces;
a processor coupled to the one or more network interfaces and configured to execute one or more processes; and
a memory configured to store a process that is executable by the processor, the process when executed configured to:
obtain first set of measurements of a path metric for a path in a network that are measured using periodic probing of the path;
obtain a second set of measurements of the path metric for the path that are measured using fine-grained probing of the path at a higher frequency than that of the periodic probing by providing a trigger pattern comprising a set of feature vectors to a router associated with the path, wherein the router initiates the fine-grained probing of the path when measurements in the first set of measurements match the trigger pattern;
generate a predictive model that predicts values of the path metric, based on the first set of measurements and on the second set of measurements; and
cause, based on a value of the path metric predicted by the predictive model, traffic to be rerouted from the path to another path in the network,

wherein the second set of measurements is obtained based on a control strategy that optimizes an accuracy of the predictive model while minimizing an amount of the fine-grained probing performed along the path.
