Inference-based network route control

Abstract

Described herein is an inference-based approach to process network route definitions, e.g. routes received from other network devices according to a defined routing protocol. In examples, at least one proposition is defined that relates to at least one property of the route. Probabilities are also defined in association with the proposition. A first probability may be indicative of a randomly-selected network route and a second probability may be indicative of randomly-selected network route that is suitable for use in routing network traffic. In certain examples, a probability that a given route is malicious or erroneous may be computed. Probabilities may be calculated by processing historical routing data, such as network route definitions that are labelled as suitable for routing traffic. Probabilities may also be evaluated cumulatively over multiple routing policy elements. Final actions may be made by applying a configurable range or threshold to an output confidence value.
