Abstract: A computing device receives information associated with a server computing device and a plurality of client computing devices, each client computing device communicatively coupled to a router device. The computing device receives, for each respective client computing device of the plurality of client computing devices, TCP packet capture data associated with the respective client computing device. The computing device accesses an expected average packet round trip time (APRTT) for a client computing device from among the plurality of client computing devices. The computing device performs a comparison of a real-time APRTT for the client computing device and the expected APRTT for the client computing device. The computing device generates user interface imagery based on the comparison.

Abstract: Channel information is accessed that identifies a plurality of channels, and for each channel a multicast address to which packets carrying channel content are addressed. Multicast data rate information is obtained from a plurality of routers that identifies, for each respective router, a real-time data rate of data addressed to a multicast address being routed by the respective router. It is determined, based on the multicast data rate information, that an output channel data rate of a first channel of the plurality of channels is lower than an expected output channel data rate that corresponds to the first channel. Information indicating that the first channel has an output channel data rate that is less than the expected output channel data rate is presented on a display device.

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.

Abstract: Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for controlling Quality of Service (QoS) within a service provider network by retrieving from the network QoS related data, processing the retrieved QoS related data via one or more time series prediction algorithm to determine QoS prediction data, and responsively generating network management or configuration commands adapted to ensure continued services delivery in accordance with QoS requirements.

Abstract: A Mapping of Address and Port using Translation (MAP-T) border relay controller for managing and controlling a MAP-T network. Configuration and performance data are collected, by a border relay configuration collector, from one or more MAP-T border relay nodes of a MAP-T network. Internet Protocol (IP) flow data are collected, by an IP flow data collector, across one or more Internet peering routers coupled to the MAP-T network. A network anomaly that impairs performance of the MAP-T network is analyzed, by a logic algorithm module, using the configuration and performance data collected by the border relay configuration collector and the IP flow data collector. A network translation capability of the MAP-T network is reconfigured based on the analysis of the network anomaly and/or availability of network resources.

Abstract: External border gateway protocol peer analysis is disclosed. For each of a plurality of external border gateway protocol (EBGP) routers in a first autonomous system (AS), corresponding EBGP peer information about at least one EBGP peer router of the respective EBGP router is obtained. User interface imagery that comprises a plurality of EBGP router controls, each EBGP router control corresponding to one of the plurality of EBGP routers, is presented on a display device. A router selection input that identifies a first EBGP router control of the plurality of EBGP router controls is received, the first EBGP router control corresponding to a first EBGP router of the plurality of EBGP routers. In response to receiving the router selection input, user interface imagery that identifies the at least one EBGP peer router of the first EBGP router is presented on the display device.
