    Abstract: 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.

    Abstract: 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.

    Abstract: Modem reclamation systems and methods for optimizing optical modem use in a network include determining costs and capacity range for Lx adjacencies in the network based on Lx information and L0 information, wherein Lx is a digital layer with routed traffic and L0 is a media layer with optical modems that are reclaimed when their utilization is reduced in the digital layer; determining an order of Lx connection moves that minimizes the costs of the Lx adjacencies, to reclaim or minimize the optical modem use; and performing the Lx connection moves based on the order and updating the Lx adjacencies.

    Abstract: Systems and methods for bandwidth optimization in a network include monitoring a state of the network, wherein the network is a connection-oriented network; utilizing analytics based on the monitoring to predict trends, create triggers, and determine updates to policy associated with the network; and performing bandwidth optimization on one or more connections based on the trends, the triggers, and the policy, wherein each of the one or more connections has one or more of a Wave Division Multiplexing (WDM) component, a Time Division Multiplexing (TDM) component, and a packet component, and wherein the bandwidth optimization finds the one or more connections with inefficient resource usages and moves the one or more connections, in one or more of time and space, to more optimal paths.
