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

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.

Data network and execution environment replication for network automation and network applications

Systems and methods for instantiating a network service in a network include receiving a service request for a network service; determining network resources in the network to instantiate the network service; determining a price for the network resources utilizing forecasts with adjustments to the price based on a current network status; providing the price in response to the service request; and responsive to acceptance of the price, causing instantiation of the network service through the network resources in the network.

Network service pricing and resource management in a software defined networking environment

Traffic-adaptive network control systems and methods for a network, implemented by a server, include monitoring data associated with the network; generating a traffic forecast based on the monitored data; generating a schedule of actions based on a comparison of the traffic forecast to observed data; and causing orchestration of the actions in the network based on the generated schedule. The network can include a Software Defined Networking (SDN) network.

Traffic-adaptive network control systems and methods

A method for path computation in a network includes determining dynamic link weights for links in the network, responsive to a request for a path, for a connection, between a source node and a destination node in the network with a requested bandwidth amount, wherein the dynamic link weights, for each link, are based on a current status of the link and a future status of the link; determining one or more paths for the request based on the dynamic link weights; and selecting a path of the one or more paths to minimize cost in the network. The method can be implemented through a Software Defined Networking (SDN) controller.

Optical and packet path computation and selection systems and methods

Modem reclamation systems and methods for optimizing optical modem use in a network include determining costs and capacity range for Ladjacencies in the network based on Linformation and Linformation, wherein Lis 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 Lconnection moves that minimizes the costs of the Ladjacencies, to reclaim or minimize the optical modem use; and performing the Lconnection moves based on the order and updating the Ladjacencies.

Multi-layer modem reclamation systems and methods

Systems and methods for a representative bandwidth calculation in a network include receiving a request for representative bandwidth information; obtaining network measurements; combining, filtering, and retiming network measurements based on the request to determine the representative bandwidth information. The systems and methods convert the combined, filtered, and retimed network measurements into the representative bandwidth information which has an additive property in an algebraic domain. The additive property enables the representative bandwidth information to be used for admission control, overbooking determinations, network planning, and/or dynamic pricing in the network.

Representative bandwidth calculation systems and methods in a network

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.

Bandwidth optimization systems and methods in networks

Systems and methods are described for network service pricing and service resource management, implemented by a server communicatively coupled to a Software Defined Networking (SDN) network configured to provide the network service. The systems and methods includes receiving a service request for a network service in the SDN network; determining one or more price categories and one or more network resources for the service request, wherein the network resources are selected to instantiate the network service; adjusting a price of the network resources by adjusting the price within a range of the price categories based on current and known future network information of the SDN network; and responsive to acceptance of the price, instantiating the network service through the network resources in the SDN network.
