1. A method comprising
determining, by a network controller, packet congestion on a network path using an inflection point detection mechanism (IPDM);
detecting, by the network controller, a potential inflection point in response to a one-way delay (OWD) of a first packet being lesser than an OWD of a second packet by a quantity greater than a function of a difference of inter departure time (IDT) between the first packet and the second packet; and
determining, by the network controller, an inflection point in congestion of the network path based on the potential inflection point.
