A system and method for monitoring network connection quality utilizes software installed on a user computer to monitor a first network connection to a target server used for a desired activity and a second network connection to a benchmark server. Various network quality metrics are recorded and compared for each of the connections and displayed on a visual display so that the user may easily and accurately judge the health of the connection to the target server.

The present application relates to communications between a partner network and a wide area network (WAN) via the Internet. Although Internet service providers may act as autonomous systems, the WAN may control routing from the partner network by advertising unicast border gateway protocol (BGP) address prefixes for a plurality of front-end devices in the WAN. An agent in the partner network measures a plurality of paths to a service within the WAN. Each of the plurality of paths is associated with one of the plurality of front-end devices and a respective unicast BGP address prefix. The WAN selects a path within the WAN for the service. The WAN exports a routing rule to the agent. The agent forwards data packets for the service to the respective BGP address prefix via the Internet. The WAN receives data packets for the service of the partner network at the selected device.

The WAN advertises unicast border gateway protocol (BGP) address prefixes for a plurality of front-end devices in the WAN. An agent in the partner network measures a plurality of paths to a service within the WAN. Each of the plurality of paths is associated with one of the plurality of front-end devices and a respective unicast BGP address prefix. The agent provides measurements of the plurality of paths to the WAN. The WAN selects a path within the WAN for the service. The agent receives a routing rule specifying a unicast address prefix for a selected device of the plurality of front-end devices of the WAN. The agent forwards data packets for the service to the respective border gateway protocol address prefix of the selected device via the Internet.

Provided is a remote control system and a method enabling packets, related to a control signal and simultaneously transmitted from a controller to a plurality of controlled devices, to be received by the controlled devices without a difference in delay. Edge nodes that are packet transfer devices are provided on communication paths between a controller provided on a network and a plurality of controlled devices provided in a location. The edge nodes each include a transfer processing unit that transfers the packets from the controller to the controlled devices, and a timing control unit that controls transmission timing of the packets in the transfer processing unit to reduce a difference in arrival time of a plurality of packets simultaneously transmitted from the controller to the plurality of controlled devices, at the plurality of controlled devices.

Systems, methods, and computer-readable media including software logic are provided for optimizing Border Gateway Protocol (BGP) traffic in a telecommunications network. In one embodiment, systems and methods include, with a current state of one or more inter-Autonomous Systems (AS) links, causing performance of an action in the telecommunication network, determining a metric based on the action to determine an updated current state of the one or more inter-AS links, and utilizing the metric to perform a further action to achieve one or more rewards associated with the one or more inter-AS links.

A network administration device may include one or more processors to receive operational information regarding a plurality of network devices; receive flow information relating to at least one traffic flow; input the flow information to a model, where the model is generated based on a machine learning technique, and where the model is configured to identify predicted performance information of one or more network devices with regard to the at least one traffic flow based on the operational information; determine path information for the at least one traffic flow with regard to the one or more network devices based on the predicted performance information; and/or configure the one or more network devices to implement the path information for the traffic flow.

Dynamic and self-healing optimized traffic rerouting is provided. A system and method are described for determining and implementing optimized traffic routing decision. A route orchestration system monitors network resource performance characteristics information for identifying a traffic redirection triggering event and for determining an optimized traffic control decision based on the network resource performance characteristics information. The decision may include software defined networking (SDN) instructions that may be communicated to one or more network resources (e.g., PE devices, P devices, and/or routers) that may cause traffic to be rerouted the one or more targeted servers. For example, the optimized traffic control decision may be determined to improve load balancing amongst performing servers and other network resources in the network while reducing or minimizing administrative costs. Network resources may include a programmatic component that allows the optimized traffic control decision determined by the route orchestration system to be implemented by the resource.

In one aspect, a computerized method includes the step of providing process monitor in a Gateway. The method includes the step of, with the process monitor, launching a Gateway Daemon (GWD). The GWD runs a GWD process that implements a Network Address Translation (NAT) process. The NAT process includes receiving a set of data packets from one or more Edge devices and forwarding the set of data packets to a public Internet. The method includes the step of receiving another set of data packets from the public Internet and forwarding the other set of data packets to the one or more Edge devices. The method includes the step of launching a Network Address Translation daemon (NATD). The method includes the step of detecting that the GWD process is interrupted; moving the NAT process to the NATD.

Techniques for in-situ passive performance measurement are described. In one embodiment, a method includes receiving a data packet at a first network element, determining whether measurement information is to be collected for the data packet, providing one or more measurement fields for the data packet based on a determination that measurement information is to be collected for the data packet in which at least one measurement field identifies a measurement type, and forwarding the data packet to a second network element. The method further includes determining, by the second network element, the measurement type for the data packet, and performing one or more actions based on the measurement type.
