    Abstract: Techniques are presented herein for determining equal cost multi-path (ECMP) performance health in a network. In accordance with an example embodiment, a method is provided that involves obtaining information indicating ECMP paths in a network, the network comprises of a plurality of nodes that includes at least one branch node. The method includes configuring the branch node to obtain ECMP performance metrics, and obtaining the ECMP performance metrics from the branch node. The method further includes analyzing the ECMP performance metrics to determine ECMP performance health of the branch node.

    IPC: H04L12/24

    Abstract: A method is performed at one or more entities configured to configure and provide assurance for a service enabled on a network. The service is configured as a collection of subservices on network devices of the network. A definition of the service is decomposed into a sub service dependency graph that indicates the sub services and dependencies between the subservices that collectively implement the service. Based on the subservice dependency graph, the sub services are configured to record and report sub service metrics indicative of sub service health states of the sub services. The sub service metrics are obtained from the subservices, and the subservice health states of the subservices are determined based on the sub service metrics. A health state of the service is determined based on the subservice health states. One or more of the sub services are reconfigured based on the health state of the service.

    Abstract: A method comprises configuring a service as a collection of subservices on network devices of a network, and decomposing a definition of the service into a subservice dependency graph that indicates the subservices and dependencies between the subservices that implement the service. The method further comprises, based on the subservice dependency graph, configuring a subservice among the subservices to record and report a subservice metric as an indicator of subservice performance. The method further comprises determining a rate at which to obtain values of the subservice metric from the subservice, determining a confidence interval for the values of the subservice metric, and obtaining the values of the subservice metric from the subservice at the rate, to produce values for monitoring the subservice. The method also includes determining whether at least one of the values for monitoring the subservice is within the confidence interval.
