Systems and methods for predicting future traffic loads of outgoing interfaces on network devices

Abstract:

A disclosed method may include (1) sampling traffic forwarded by a network device in accordance with certain prefixes, (2) determining, based at least in part on the sampling of traffic, a subset of the prefixes whose usages satisfy a certain threshold, (3) computing a plurality of hit probabilities that each represent a relative likelihood that one of the subset of prefixes is used by the network device to forward the traffic, (4) identifying a plurality of outgoing interfaces that carry the traffic in connection with the subset of prefixes, (5) identifying a plurality of prefix-specific loads of the outgoing interfaces, and then (6) predicting a plurality of future traffic loads of the outgoing interfaces based at least in part on (A) the hit probabilities of the subset of prefixes and (B) the prefix-specific loads of the outgoing interfaces. Various other systems and methods are also disclosed.
