1. A method for determining health of a link in a communications network comprising a plurality of network devices, the method comprising:
establishing a first data link and a second data link between two endpoints of the communications network;
for each of the first and second data links, determining a first metric based on:
a first scaling factor indicative of a rate at which link health degrades over time, and a time at which a most recent packet was received on the respective data link;

for each of the first and second data links, determining a second metric determined based on a second scaling factor for controlling how often to probe the first and second data links in addition to regular data packets; and
based on the first and second metrics, selecting one of the first or second data links.
