Résumé

L’article expose le projet expérimental de lasip pour la gestion et la supervision de son réseau de transit prévoyant un système centralisé de recueil et d’élaboration des données en provenance des commutateurs du réseau. Les anomalies de charge du réseau ainsi que les pannes sont visualisées graphiquement sur des panneaux muraux, aussi bien au niveau national qu’au niveau régional. De plus, des applications ont été conçues pour analyser les corrélations entre les événements observés, détecter les origines communes et prévoir l’éventuelle diffusion de l’encombrement que pourraient provoquer de graves étranglements de flux de trafic. Après une brève description du réseau italien, l’article décrit la structure et les fonctions du Centre de supervision national, ainsi que les méthodes mises en œuvre pour détecter et localiser les situations d’encombrement anormales, et traite enfin des prospectives de futurs développements.

Abstract

The Italian Telecommunication Companysip has started an experimental project for transit network supervision. The project, calledcsn, provides a centralized system to collect and work out data coming from the network exchanges. Load and failure anomalies are singled out on graphic wall display by using regional and national maps. Besides, some sofware applications allow to gather the present anomalies by perceiving their similarities and to point out the congestion diffusion due to serious traffic streams obstructings. After a brief description of the italian telephone network, the csn structure and functionality are described by pointing out the critérium on which an anomalous congestion is perceived.
