Systems and methods include obtaining overlay telemetry data from a plurality of overlays, wherein each overlay is an application and there is a corresponding telemetry adaptor for each overlay; obtaining underlay telemetry data from one or more underlays, wherein each underlay includes physical infrastructure for supporting one or more of network, compute, and store functions for the plurality of overlays; analyzing the overlay telemetry data and the underlay telemetry data via a Key Performance Factor (KPF) model that correlates one or more of the plurality of overlays and the one or more underlays together; responsive to an anomaly or a threshold crossing based on the KPF model, performing a Root Cause Analysis (RCA) to identify a root cause of the anomaly or the threshold crossing; and mapping one or more actions with associated priorities to the root cause utilizing one or more remediation modules each associated with an overlay.

Systems and methods for precisely generalized and modular underlay/overlay service and experience assurance

A content caching system enables an NDN network to place content closer to each end user(s) and to provide an explicit path for the target end user(s) to that content for better performance just in advance of users' anticipated request(s). The apparatus includes NDN routers and SDN controller employing a content commander, at least a content placement agent and at least one content analysis agent.

Systems and methods for intelligent routing and content placement in information centric networks

An optimization platform system includes a network interface configured to communicate with a plurality user devices and a plurality of servers in a network; a processor communicatively coupled to the network interface; and memory storing instructions that, when executed, cause the processor to obtain network measurements including Quality of Service (QoS) measurements and one of measured Quality of Experience (QoE) measurements and inferred QoE measurements from the QoS measurements for one or more streams in the network, wherein each of the one or more streams has a type selected from a group consisting of a video stream, a Voice over Internet Protocol (VoIP) call, a gaming stream, and an Augmented Reality (AR)/Virtual Reality (VR) stream, and wherein the QoE measurements and the inferred QoE measurements of each of the one or more streams is based on the type of the respective stream, analyze the QoE measurements to determine poor QoE in the network, determine remedial actions in the network to repair the poor QoE, and cause implementation in the network.

Adaptive systems and methods enhancing service quality of experience

Systems and methods for adaptive Over-the-Top (OTT) content optimization based on Quality of Experience (QOE) are implemented in an OTT optimization platform communicatively coupled to a plurality of devices in a network. The system and methods include receiving a plurality of inputs comprising network inputs, service and software inputs, and QOE inputs; analyzing the plurality of inputs with respect to one or more OTT content streams to perform an optimization thereof; determining adjustments in the network based on the optimization; and one of notifying a network operator of the adjustments and automatically causing the adjustments in the network.

Systems and methods for adaptive over-the-top content quality of experience optimization

Network replica systems and methods include, via a server, a group of servers, or in a cloud computing environment, communicating with one or more management systems and one or more networks associated with the one or more management systems via one or more Application Programming Interfaces (APIs); obtaining data from the one or more management systems and/or the one or more networks; storing the data in a database of record which defines a detailed model of a current state of the networks; and applying one or more assertions to data of interest in the database of record to emulate behavior in the one or more networks, wherein the assertions map actual device, process, business, architecture, and technology behaviors onto the data of interest from the database of record to emulate the behavior, wherein the database of record and the applied one or more assertions include a network replica of the networks.
