METHODS FOR EVENT PRIORITIZATION IN NETWORK FUNCTION VIRTUALIZATION USING RULE-BASED FEEDBACK

摘要

A method is implemented by an event collector to utilize feedback from an event handler to prioritize event forwarding to the event handler. The method includes receiving feedback from the event handler in response to a successful match-action in a rules engine, the feedback including a derived condition which is a generalized version of a condition stored in the match part of a rule, determining whether the derived condition is stored in an event prioritizer, and storing the derived condition in the event prioritizer with initial expiration timer and hit counter, in response to the derived condition not being present in the event prioritizer, and updating a hit counter and expiration timer of the derived condition in the event prioritizer, in response to the derived condition being present in the event prioritizer.
