Abstract: A network analytics controller is established in a network. The network includes a plurality of nodes. A plurality of network analytics agents is established; each agent at a node of the network. Network analytics configuration parameters, including a network analytics scope, are received at the networks analytics controller. A task is assigned to each agent at a node determined to be within the network analytics scope, the task comprising that portion of the network analytics specified in the network analytics configuration parameters relevant to the corresponding node. The assigned task is performed at each agent assigned a task. The networks analytics controller receives the results of each performed task, and aggregates the received results.

Abstract: Installing on a node of a computer network, an agent of a network system. The installed agent receives a network task via the network. The network task involves a second node of the network. The receiving agent generates a probe implementing the task and targeted to the second node. Either the receiving agent or the generated probe generates a command for the second node. The command is related to the probe and can be in the form of a data link layer protocol data unit for network operations, administration, and maintenance (OAM). The agent or node that generates the command communicates the command to the second node. The second node executes the communicated command. The second node communicates an acknowledgment of the executed command to the first node.

Abstract: A network analytics controller in a computer network receives specification of a network analysis task. The controller creates maplets. Each maplet corresponds to an agent executing on a network node in the computer network. Each maplet specifies the network data collection configuration, collected data processing, and processed data reporting to be performed to support the network analysis task at the node executing the corresponding agent. The controller communicates the maplet corresponding to the agent over the computer network to each agent. Each agent receiving a maplet configures its corresponding network node for network data collection, collected data processing, and processed data reporting in accordance with the received maplet. Each agent receiving a maplet collects and processes network data, and reports the processed data to the controller, in accordance with the configuration. The controller aggregates, as the result of the network analysis task, the data reported from each agent.

Abstract: In one implementation, the power consumption by network devices may be managed by accessing a routing protocol that manages an allocation of processing resources in a network. The routing protocol may be used for generating a first configuration, for which a utilization of resources may be determined. A first cost for the first configuration may be determined. A second configuration may be identified to support the utilization of the resources. A second cost may be determined for the second configuration. The first cost may be compared to the second cost. The prospective performance of the network for the second configuration may be assessed. Based on the results of the comparison and the assessment, the network may be configured to use the second configuration. Processing resources may be activated on inactive network devices to support the second configuration and deactivated on active network devices that are not utilized in the second configuration.

Abstract: Disclosed is a technique for data network congestion diagnosis using remote estimation of round-trip delays. A monitoring node transmits test messages between network nodes and measures the transit times between when the test messages are transmitted from, and when they return to, the monitoring node. A path delay between network nodes is determined based on the measured time delays. The techniques for determining network path delay are also utilized in conjunction with a three phase test procedure for diagnosing network congestion problems. Due to various network topologies and routing tables, certain confirmatory checks may be required to determine whether the procedures of the first or second phase test procedures are appropriate for particular path segments. Further, queuing delays may be determined by subtracting traffic independent delays from the measured transit times of the test messages, and such queuing delays may be used to determine the path delays.
