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.

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.

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.

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.

A method and apparatus for performing traffic engineering, e.g., allocating bandwidth, on a wireless access network are disclosed. 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.

A method and apparatus for enabling prioritization of signaling messages in a communication network are disclosed. For example, the method receives at least one signaling message, and classifies each of the at least one signaling message. The method schedules each of the at least one signaling message for processing, and discards selectively one or more signaling messages that have been scheduled under an overload condition.

Preemptive based radio access control is facilitated. Queue data is received, wherein the queue data corresponds to a set of requests for highly prioritized communications included on a prioritized queue. The queue data is used to determine whether a set of conditions for involuntarily terminating a radio communication session has been met. Session data corresponding to characteristics for each of a plurality of radio communication sessions are also received and utilized to determine which of the plurality of radio communication sessions to terminate if the set of conditions for involuntarily terminating a radio communication session have been met.
