Correlating end-to-end passive measurements using hierarchical filters

摘要

A system (DGM) is dedicated to end-to-end parameter measurement management for a network management system (NMS) of a packet-oriented communications network including a multiplicity of peripheral equipments (EP). The parameter measurement management system (DGM) comprises management means (MG) adapted to send selected peripheral equipments (EP) selected filter definitions associated with selected filter identifiers, correlation means (MCN) adapted to correlate each notification including a selected filter identifier received from an ingress peripheral equipment (EP-1) with a selected set of notifications received from egress peripheral equipments (EP-2, EP-3) and including a filter identifier having one or more relationship links with the selected filter identifier, and calculation means (MCM) adapted to derive parameter measurements from values contained in the correlated notifications.
