First Claim
Patent Images
1. An intelligent network management device, disposed in a software-defined network (SDN) and connected to a SDN switch and a SDN controller used to control the SDN switch, the intelligent network management device comprising an analytic unit portion and a processing unit portion, wherein:
- the analytic unit portion of the intelligent network management device is configured to conduct an analysis according to packets received by the intelligent network management device via the SDN switch to determine whether a given event has occurred and notify the processing unit portion of the intelligent network management device when the given event is determined to have occurred; and
the processing unit portion of the intelligent network management device is configured to generate and send an instruction to the SDN controller to change configurations of the SDN switch when the analytic unit portion of the intelligent network management device determines that the given event has occurred, wherein the configurations of the SDN switch are changed by the processing unit portion as directed by the analytic unit portion when the analytic unit portion determines that the given event has occurred so that the SDN switch sends packets originally destined to the intelligent network management device to another device on the SDN.
