Title
(EN) IDENTIFICATION OF CANDIDATE PROBLEM NETWORK ENTITIES
(FR) IDENTIFICATION D'ENTITÉS DE RÉSEAU PROBLÉMATIQUES CANDIDATES
Abstract
(EN) The detection of network communication problems in networks that have multiple end nodes, and multiple transit nodes in between. One or more of the end nodes monitors one or more flows, creates associated flow information including performance information for each flow, and then reports the flow information. A system then estimates, for each of multiple flows within the network, a likely path that network traffic takes through that network. The system might then use performance information for each of the reported flows to identify at least one candidate problem network entity that is common amongst the estimated paths of the at least the subset of the plurality of flows.
(FR) L'invention concerne la détection de problèmes de communication réseau dans des réseaux comprenant une pluralité de nœuds d'extrémité et une pluralité de nœuds de transit intercalés. Un ou plusieurs des nœuds d'extrémité surveillent un ou plusieurs flux, génèrent des informations de flux associées comprenant des informations de performance pour chaque flux, et rapportent ensuite les informations de flux. Un système estime ensuite, pour chacun d'une pluralité de flux dans le réseau, un trajet potentiel pouvant être emprunté par le trafic dans ce réseau. Le système peut ensuite utiliser des informations de performance pour chacun des flux rapportés afin d'identifier au moins une entité de réseau problématique candidate commune aux trajets estimés du ou des sous-ensembles de la pluralité de flux.
