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.

Abstract: An electrical device cover includes an access panel having an orifice and an adapter plate configured with an opening dimensioned to receive the operative face of an electrical device. The front face of the access panel includes a depressed platform surrounding the orifice and dimensioned to receive the adapter plate. An interlock between the access panel and the adapter plate is provided by channels formed on the rear face of the adapter plate and the front of the access panel and fillets formed on the access panel, and adapter plate, the fillets being seated in the channels. The adapter plate includes a pair of trapezium flanges which define the longitudinal boundaries of the adapter plate and which are received in the depressed platform.

Abstract: A kit for covering electrical devices includes a housing having a rear panel which receives adapter plates. An opening in an adapter plate is defined by a forwardly tapered chamfered wall. A frustum insert having a chamfered wall opening may be received in the adapter plate opening and successive frustum inserts, each having a smaller chamfered wall opening, may be inserted within the opening of the prior insert. Each of the openings is dimensioned to receive the face of a different electrical device. A frustum plug having a rectangular toggle switch opening can be received in one of the chamfered openings. The top and side of the housing include arrays of hinge pins and a lid includes mating arrays of hinge knuckles. The lid is mounted to either array of pins. Selected pins have enlarged heads to prevent inadvertent disengagement.
