摘要： In one embodiment, a learning machine may be used to select observer nodes in a LLN such that the liveness of one or more nodes of interest may be monitored indirectly. In particular, a management device may receive network data on one or more network traffic parameters of a computer network. The management device may then determine, based on the network data, a candidate list of potential observer nodes to monitor activity or inactivity of one or more subject nodes. The management device may then dynamically select, using a machine learning model, a set of optimized observer nodes from the candidate list of potential observer nodes.

摘要： In some examples, a method for converged system compliance checking can include identifying a converged system compliance checking field for hardware in a converged system. The compliance checking field can, for example, be based on the purpose of the hardware. The method can further include identifying baseline compliance data for the compliance checking field, identifying actual compliance data for the compliance checking field by testing the hardware, comparing the actual compliance data to the baseline compliance data, and determining whether the hardware is in compliance with the converged system based on the comparison between the actual compliance data and the baseline compliance data.

摘要： A system and apparatus for monitoring networks and quality-of-service elements within networks. Probes placed at strategic locations throughout the network activate at predetermined intervals or upon predetermined events, conduct tests emulating actual user experience, and report the results of the tests to a controller. The data collected by the controller is used to maintain the integrity of the network and to evaluate the user experience within the network.

摘要： A method for network adaptation includes receiving, by an adaptation coordinator of a virtual network, a performance measurement generated at a performance checkpoint located in the virtual network. The method also includes generating, by the adaptation coordinator, a first update of a service-specific configuration of the virtual network. The first update includes at least one of a modification of a performance checkpoint configuration, a modification of a Virtual Network Function (VNF) configuration, a modification of a protocol configuration, a modification of a resource allocation input, or a modification of a logical graph. The service-specific configuration includes a configuration of a plurality of logical nodes and a plurality of logical links of the virtual network in accordance with a service-specific data plane logical topology.

摘要： An information terminal 10 successively receives a plurality of packets that configure distribution data from an information distribution server 20, and requests the information distribution server 20 to change a bit rate of the packets that configure the distribution data, if it is judged that congestion occurs in communication with the information distribution server 20 based on a change in time interval from transmission to reception of each of the successively received packets, and if it is judged that a packet loss rate, which is a rate of a loss packet corresponding to a loss included in the packets transmitted from the information distribution server 20 and calculated based on the successively received packets, is increased as compared with a value obtained by multiplying a packet loss rate before the packets that configure the distribution data are received, by a predetermined weight.

摘要： Systems and methods for integrating ultra-fast programmable networks in microgrid are disclosed to provide flexible and easy-to-manage communication solutions, thus enabling resilient microgrid operations in face of various cyber and physical disturbances. The system is configured to establish a novel software-defined networking (SDN) based communication architecture which abstracts the network infrastructure from the upper-level applications to significantly expedite the development of microgrid applications, develop three functions of the SDN controller for microgrid emergency operations, including time delay guarantee, failover reconfiguration and rate limit and create a hardware-in-the-loop cyber-physical platform for evaluating and validating the performance of the presented architecture and control techniques.

摘要： A the network-side distribution point in a telecommunications network includes an input measurement function which monitors the total power delivered to the power combiner from the various customer premises, and an output measurement function which monitors the total power requirements of the components of the distribution point. The data from these monitoring functions are used by a power extraction control unit to control the combiner/extraction unit to draw power from the forward power feed to makes up any shortfall in the power required to operate the components. This allows each customer premises system to deliver power to the distribution point at a rate determined only by the services it is itself using, and without any need for co-ordination between the distribution point and the customer premises systems.
