A method and system for managing traffic in a network. For each label switch path of at least two logical switch paths, logical paths are identified. Each label switch path begins at a first provider edge and ends at a second provider edge. Most recent data received from the first provider edge is transmitted to the second provider edge via a selected logical path.

In one embodiment, a system includes a switch controller configured to communicate with a plurality of network devices in a network. The switch controller includes a processor and logic integrated with and/or executable by the processor. The logic is configured to determine a throughput associated with a workload in the network and select an optimum location for the workload in the network based on the throughput associated with the workload. In another embodiment, a computer program product includes a computer readable storage medium having program code embodied therewith. The embodied program code is readable/executable by a processor to cause the processor to determine a throughput associated a workload in a network. The embodied program code is also readable/executable by the processor to cause the processor to select an optimum location for the workload in the network based on the throughput associated with the workload.

In some examples, method includes receiving, with a software-defined network (SDN) controller in an SDN containing a plurality of controlled network nodes, a dynamic network parameter for the SDN from a controlled network node in the SDN, selecting, with the SDN controller, an adjusted spanning tree protocol (STP) path cost value for a path cost along a datapath between a source network node and a destination network node in the SDN based on the received dynamic network parameter, and installing, with the SDN controller, the adjusted STP path cost value on controlled network nodes along the datapath.

The present invention relates to a method of managing congestion in a multi-path network, the network having a plurality of network elements arranged in a plurality of switch stages and a plurality of network links interconnecting the network elements, the method comprising the steps of detecting congestion on a network link, the congested network link interconnecting the output port of a first network element with a first input port of a second network element in a subsequent switch stage; identifying an uncongested network link connected to a second input port of said second network element; and directing future data packets on a route across the multi-path network which includes the identified uncongested network link. Also provided is a multi-path network and an Ethernet bridge or router incorporating such a multi-path network.

Systems and techniques are described which improve performance, reliability, and predictability of networks without having costly hardware upgrades or replacement of existing network equipment. An adaptive communication controller provides WAN performance and utilization measurements to another network node over multiple parallel communication paths across disparate asymmetric networks which vary in behavior frequently over time. An egress processor module receives communication path quality reports and tagged path packet data and generates accurate arrival times, send times, sequence numbers and unutilized byte counts for the tagged packets. A control module generates path quality reports describing performance of the multiple parallel communication paths based on the received information and generates heartbeat packets for transmission on the multiple parallel communication paths if no other tagged data has been received in a predetermined period of time to ensure performance is continually monitored. An ingress processor module transmits the generated path quality reports and heartbeat packets.

The present disclosure discloses a method and device for receiving and sending a message, a channel unit and communication equipment. The method for receiving and sending the message of the present disclosure specifically includes that: a channel unit receives a message sent by equipment born by an equipment network interface; the channel unit judges whether the received message is a message required to be processed by a CPU or not; when a judgment result is that the received message is the message required to be processed by the CPU, the channel unit sends the message to the CPU, receives a response message returned by the CPU, and directly forwards the response message to the equipment; and when the judgment result is that the received message is not the message required to be processed by the CPU, the channel unit generates and sends a corresponding response message to the equipment.

In a multiple interface, low power and lossy network comprising a plurality of nodes, a low transmission power and medium transmission power topology are defined for the network and a channel-hopping schedule is defined for the devices operating in each topology. A sender determines that data is capable of being transmitted via a link on the low transmission power topology. The sender determines the transmission parameters for the transmission of the data over the link on the low transmission power topology and determines a low transmission power channel for transmission of the data. The sender transmits the determined channel and the transmission parameters to the receiver. The sender transmits the data via the determined channel in the low transmission power topology.

The virtual broadcast system of the present invention optimizes the routing of digital content among nodes along overlay networks that are dynamically reconfigured based upon forecasts of frequently-changing congestion levels of component interconnections within an underlying network. In the context of delivering streaming video over the Internet to large numbers of concurrent users, the present invention makes efficient use of the limited capacity of congested ASN peering points by employing deep learning techniques to forecast congestion levels across those ASN peering points and, based on those forecasts, to optimize the routing of video content along dynamically reconfigured overlay networks. The virtual broadcast system handles unscheduled as well as scheduled events, streams live as well as pre-recorded events, and streams those events in real time with minimal delay in a highly scalable fashion that maintains a consistent QoE among large numbers of concurrent viewers.

A method for scoring a service node includes: obtaining address information of the service node; monitoring the service node according to the address information of the service node, and obtaining a plurality of performance evaluation information of the service node; and scoring the service node according to the plurality of performance evaluation information.

Systems and methods include steps of determining a state of a network based on telemetry data; determining a value of a reward associated with the state; determining an action to take on the network to bring the network to a next state that is expected to have a better than or equal to value of the reward; and causing the action to be implemented in the network. The steps can also include continuing the determining steps and the causing step.
