Abstract: The disclosed technology is directed towards locating and counting unused nodes, such as free Internet Protocol version 4 (IPv4) address blocks. A hierarchical structure of nodes is created from an origin block to a specified lower level, and the hierarchical structure is processed using mapping and eliminating to locate free nodes. A first node group comprises node(s) in use, a second node group identifies intermediate subnets between the first node of the first node group and the specified origin block, and a third node group identifies any subnets hierarchically below node(s) in use. Unused (free) node count information is obtained based on nodes below the origin block that are not in the first node group, the second node group, or the third node group.

Abstract: Adaptable resiliency for a virtualized radio access network (vRAN) framework is disclosed. A resiliency management component can determine vRAN topological adaptations that can reflect resiliency requirements of service instance(s). Accordingly, sufficient redundant vRAN components to satisfy the resiliency requirements can be deployed. However, unlike conventional redundancy techniques that can determine a highest level of redundancy and then apply that relative to all supported services, the disclosed subject matter can avoid over-deploying redundant vRAN components, e.g., redundant components exceeding the resiliency requirement of a service instance, resulting in lowered monetary and non-monetary costs to maintain a vRAN. Moreover, as the services change, the topology of the vRAN can be automatically adapted to purge excessive redundancies, add newly required redundancies, etc., which can facilitate propagating an adequate but lean vRAN topology that is sufficiently resilient.

Abstract: The described technology is generally directed towards latency diagnostics for multiparty systems, such as a system comprising a communication network, a content delivery network (CDN), and one or more internet service providers (ISPs). A latency analyzer component can process latency data in response to a latency diagnostic trigger, such as an alert from a video quality monitoring system. The latency analyzer can determine whether latency is attributable to the communication network. If not, the latency analyzer can determine whether the latency is attributable to the CDN. If the latency is not attributable to the communication network or the CDN, the latency analyzer can determine that the latency is attributable to the ISP, and the latency analyzer can identify the ISP and generate appropriate reports and notifications.

Abstract: Aspects of the subject disclosure may include, for example, identifying a threshold value of a streaming-media key performance indicator (KPI) based on a predetermined target portion of end-user devices that provide an acceptable performance. Performance records are obtained for a content delivery network (CDN) adapted to cache and serve media content requested by the end-user devices. Predicted values of the streaming-media KPI are generated according to the performance records of the CDN and compared to the threshold value of the streaming-media KPI to obtain a comparison. An anomaly is detected according to the comparison, to indicate that a predetermined number of the predicted values of the streaming-media KPI fail to satisfy the threshold value. Other embodiments are disclosed.

Abstract: Devices, computer-readable media, and methods for predictively managing the customer experience in a content distribution network are disclosed. In one example, a method includes acquiring a system log from a component of a content distribution network, detecting an event in a report derived from the system log that has been correlated with a decline in a key performance indicator of the content distribution network, and initiating a corrective action in response to the detecting.

Abstract: The disclosed technology is directed towards locating Internet Protocol version 4 (IPv4) address blocks that are not supernets to subnet address blocks. A list of IPv4 address blocks is first processed to determine supernet/subnet relationships across octets, to remove the supernets and provide a reduced list. The reduced list is iteratively processed in descending prefix length order to identify candidate supernets at each prefix length, determine which of the candidate supernets are actual supernets, remove the actual supernets, and move the remaining candidates to a leaf list. At the end of the iterations, the leaf list contains the IPv4 address blocks that do not have subnets (are not supernets).

Abstract: Architectures and techniques are presented that improve or increase network security for networks that have network slicing capability. In addition to (or instead of) conventional network slices, various security-based network slices can be defined and/or implemented. Network traffic of a subscriber device can be assigned to one of these security based network slices. Assignment can be based on characteristics of the subscriber device and/or based on the current behavior or role of the subscriber device. Further, in response to determining that a behavior of the subscriber device satisfies a criterion (e.g., a criterion relating to malfeasance or misbehavior, a criterion relating to switching to a maintenance cycle, and so on), reassigning network traffic of the subscriber device from the currently assigned network slice to a different network slice.

For example, the method determines a number of subscriber stations (SSs) that a Base Station (BS) is capable of supporting in accordance with at least one performance objective for voice traffic, wherein the at least one performance objective for voice traffic comprises a type of codec. The method then allocates bandwidth by the base station in accordance with the number of subscriber stations that the base station is capable of supporting.

Abstract: The transport latency, processing time, and computing time in virtual functions (VFs) and physical functions (PFs) that are allocated to delay sensitive services may be assessed and stored. The assessment may be used to create latency zones for network planning or design, as well as determining in near real time the available resources to meet the service needs.
