Definitions

  • Today's networks are very distributed and can comprise of several call processing nodes.
  • a single call typically traverses across several nodes within the network. It is extremely challenging to isolate problems based on nodal alarms that are typically single event driven.
  • the invention provides a way to monitor network performance in near- real time, providing:
  • Network Performance Indicators provide a methodology of performing near real-time monitoring of complex, distributed networks. Network Performance Indicators are useful as following:
  • the present invention provides two levels of NPIs, one at solution level (E2E) and other on the node level. Nodes then have a network and nodal view as well. Combined together these NPIs provide a mechanism for fault identification and isolation.
  • a method of monitoring network performance comprising providing a first network performance indicator bearing on a performance of a network from an end-to-end perspective. Then, providing a second network performance indicator bearing on a performance of a node within the network, wherein the second network performance indicator is related to the first network performance indicator. The first and second network performance indicators are correlated to identify and isolate a problem within the node or network.
  • Figure 1 illustrates the NPI solution of the present invention and nodal framework according to one embodiment of the present invention.
  • Figure 2 shows the NPI solution of the present invention and a nodal diagram. The capability to correlate data between the E2E NPIs and nodal NPIs is key to practicing the present invention.
  • NPIs Network Performance Indicators
  • They are typically metrics built upon counters/OMs which describe the traffic flow on a large scale.
  • E2E NPIs Describe the behavior of the service from an end-to-end perspective
  • the E2E NPIs indicate that there is a problem in the network, and product NPIs indicate where the problem is.
  • the E2E & Product NPIs facilitate quick drill-down to the root cause of the disruption.
  • Figure 5 illustrates several events that may impact network performance, and their respective distinct fingerprints.
  • Figure 6 the present invention allows us to assess and/or explain NPI changes over upgrades to the network. This includes product behavioral changes and OM logic changes.
  • the present invention also allows proactive performance monitoring.
  • trending enables proactive identification of issues and engineering bottlenecks in the network.
  • Proactive trending can identify issues before they impact service.
  • Figure 8 illustrates an example of a scenario where performance monitoring is integrated into network activities. Performance monitoring may be integrated into all network activities, including but not limited to: • Software upgrades
  • Real time performance monitoring includes: • A methodology of performing real-time monitoring of complex, distributed networks
  • a single call can be impacted by any number of nodes, interfaces, routing issues, etc.
  • Performance monitoring according to the present invention addresses these challenges in the following ways:

Abstract

L'invention concerne un procédé de surveillance de performance de réseau, comprenant la mise à disposition d'un premier indicateur de performance de réseau sur la base d'une performance de réseau en termes de fonctionnement de bout en bout; ensuite, la mise à disposition d'un second indicateur de performance de réseau sur la base d'une performance d'un noeud à l'intérieur du réseau, le second indicateur de performance de réseau étant apparenté au premier indicateur de performance de réseau. Le premier et second indicateur de performance de réseau sont corrélés pour identifier et cerner un problème dans le noeud ou le réseau.
