Method and system for detecting normalization of forwarding behavior of router in core routing area

摘要

The present disclosure provides a method and system for detecting normalization of forwarding behavior of a router in a core routing area. The method includes: obtaining data flow received by ports of a core router; performing matching check to the data flow according to the data flow state table; if the data flow does not match the data flow state table, checking state of the data flow to calculate a state check result S(i); determining whether the data flow state table needs to be updated, if yes, updating the data flow state table; and determining whether the state check result S(i) is a trigger state, if yes, calculate state r of the forwarding behavior of the core router, and determining whether the forwarding behavior of the core router is abnormal according to the state r of the forwarding behavior of the core router, if yes, generating an alert log.
