Abstract:

A method and server to detect, diagnose, and mitigate issues in a network include receiving Operations, Administration, and Maintenance (OAM) data related to the network, the OAM data related to current operation of the network; instantiating a rule engine to evaluate one or more rules based on any one of the OAM data, an event, policy, and an anomaly; and performing one or more actions based on the evaluating the one or more rules. A Software Defined Networking (SDN) controller is also described.

Abstract:

A method, operated by a Software Defined Networking (SDN) controller associated with an Autonomous System (AS) with one or more peering points, each peering point with an associated router communicatively coupled to the SDN controller, the method for detecting and defending against Distributed Denial of Service (DDoS) attacks, and the method includes receiving data from the one or more peering points; detecting malicious traffic at the one or more peering points; determining a peer quality measurement for the one or more peering points; and communicating the peer quality measurement and other data associated with the malicious traffic to one or more other SDN controllers, associated with Autonomous Systems connected through the one or more peering points, to facilitate convergence of the peer quality measurement back to a nominal level.
