Abstract: Various embodiments comprise systems, methods, mechanisms, and apparatus by which a network operator such as a wireline internet service provider (ISP) may determine that an endpoint device has one or more other wireless devices tethered to it, such as a mobile handset providing dual-Wi-Fi ad-hoc tethering (i.e., connected to a high-speed Wi-Fi network while simultaneously providing Wi-Fi connections to wireless devices tethered to the mobile handset), by monitoring Transmission Control Protocol (TCP)/IP traffic flow associated with endpoint devices (i.e., to or through endpoint devices), characterizing these traffic flows in accordance with one or more error indicative criteria to establish thereby a baseline profile of error indicative criteria that is indicative of a TCP/IP traffic flow associated with an endpoint device that is not associated with tethering (e.g., a rate or number of duplicate ACKs), wherein deviations from the baseline profile of error indicative criteria beyond a threshold are indicative of a TCP/IP traffic flow associated with an endpoint device that is associated with tethering.

Abstract: Methods, systems, and apparatus for detecting and mitigating anomalous network traffic. With at least one processor in a network, information regarding network traffic flows is obtained and a classification model is generated based on the obtained information, the classification model comprising one or more classification rules for classifying network traffic as normal or anomalous. With the at least one processor in the network, the network traffic is classified as anomalous or normal based on the generated classification model and at least one mitigation action is initiated based on the network traffic being classified as anomalous.

Abstract: Various embodiments comprise systems, methods, and apparatus for allocating resources in a 5G network comprising Citizens Broadband Radio Service Device (CBSD) nodes configured for communicating via granted spectrum with customer premises equipment (CPE) supporting wireless access points (WAPs) and the like, wherein an initial small bandwidth part (BWP) is assigned to each CPE, a BWP update process provides to a policy control function a list of devices/capabilities consuming CPE bandwidth so that the PCF may calculate a new bandwidth requirement for the CPE, the new requirement being used by the CPE to generate a CPE UE capability information message for the CBSD node, the CBSD node assigning an appropriately sized BWP for the CPE.

Abstract: An improved channel access mechanism provides collision avoidance improves throughput. A communications device, e.g. an end node in a long range wireless communications system, determines that data is to be transmitted and performs a channel activity detection operation to determine if a communications channel is busy or idle. In response to determining that the channel is busy, the communications device determines a wait time based on a random number and a number of times a busy channel has been detected since determining that data is to be transmitted. The communications device uses the determined wait time in determining when to transmit.

Abstract: Methods and systems for service integrated domain name servers are described. A method for out of path border gateway protocol (BGP) validation includes receiving, at a network component, a prefix announcement. The network component denies acceptance of the prefix announcement. A BGP monitor at the network component sends the prefix announcement to an out of path validation controller. The out of path validation controller evaluates the prefix announcement against one or more validation tests, sends a validation notification based on the one or more validation tests, and programs the network component for a validated prefix announcement.

Abstract: Methods and apparatus related to characterization of digital content, such as in a content delivery and/or service provider network. In one embodiment, a method is provided for identifying characteristics of digital content by a first-pass analysis of the content data, and subsequent adjustment of results of the first-pass data analysis based on a heuristic analysis. In one variant, the first-pass analysis is based on an extant (COTS) or off-the-shelf analytics framework which generates a result; artificial intelligence and/or machine learning techniques are utilized for analyzing the result based on a multi-source or multivariate analytical framework to enable convergence of a final result having suitable level of accuracy, yet with optimized temporal and processing overhead characteristics. In one implementation, the methods and apparatus are adapted for use in a content distribution network advertisement ingestion processing system.

Abstract: Collect a full band capture spectral reading from a plurality of cable/fiber broadband network customer units (e.g., cable modems or equivalent optical units); for each of the cable/fiber broadband network customer units, construct an ideal spectral reading. For each of the cable/fiber broadband network customer units, subtract the ideal spectral reading from the full band capture spectral reading to obtain a resultant spectrum. For at least one of the cable/fiber broadband network customer units, identify a persistent deviation from zero in the resultant spectrum that does not match a known impairment type. Identify at least one new impairment type corresponding to the persistent deviation from zero. Remediation of the new impairment type can be carried out as appropriate, and/or a detection pattern can be deployed to identify future occurrences of the new impairment type.

Abstract: A mobile network operator (MNO) base station, e.g., an eNB, instructs a mobile virtual network operator (MVNO) user equipment (UE) to monitor to detect signals from base stations in its MVNO network and to report back the results. If the UE reports to the MNO base station, that it has detected signals from base stations, e.g. CBSDs, in its MVNO, the MNO base station applies one or more rules included in a stored Service Profile Identifier, corresponding to the UE, the applying of the one or more rules causes the MNO base station to disconnect or deny service to the UE. Alternatively, when it is determined that the UE did not detect a signal from a base station, e.g. a CBSD, in its MVNO, then the MNO base station provides communications service to the UE.

Abstract: Systems, methods, and devices for identifying and responding to illegitimate devices on a service provider network include computing devices that are configured to collect dynamic host configuration protocol (DHCP) information related to a device (e.g., a modem, etc.) that establishes or requests to establish an internet protocol (IP) connection to the service provider network. The computing devices may determine features based on the collected DHCP information, apply the determined features to a classification model, and predict whether the device is an illegitimate device based on a result of applying the determined features to the classification model. The computing devices may perform a responsive action (e.g., blacklist or quarantine the device, etc.) in response to predicting that the device is an illegitimate device.
