Abstract: Obtain, by a controller, from at least one provisioning database of an internet service provider, assigned bandwidth per customer for a plurality of internet service provider customers. Obtain, by the controller, from a plurality of peering entry points of the internet service provider, currently used bandwidth per customer for the plurality of internet service provider customers. Compare, by the controller, for the plurality of internet service provider customers, the assigned bandwidth per customer to the currently used bandwidth per customer, to determine at least one given customer of the plurality of internet service provider customers putatively suffering from a distributed denial of service attack. Initiate at least one remedial action for the at least one given customer of the plurality of internet service provider customers putatively suffering from the distributed denial of service attack.

Abstract: Methods and systems for a multiple domain quality of service software-defined networking (SDN) controller are described. A method includes discovering network devices in a network, collecting traffic flow data from each of the discovered network devices, collecting configuration and operational data from each of the discovered network devices, categorizing the traffic flow data into traffic flow types for presentation as a first level view, determining source and destination pairs for each traffic flow in each of the traffic flow types for presentation as a second level view, generating network device micro-topologies for each of the source and destination pairs for presentation as a third level view, mapping at least one network device characteristic for each network device in each network device micro-topology for presentation as a fourth level view, and performing corrective measures on network devices identified for issues from the presented network device characteristics.
