Title (EN) BANDWIDTH MANAGEMENT SYSTEM USING VARIABLE VIRTUAL PATHS
(FR) SYSTEME DE GESTION DE LARGEUR DE BANDE A TRAJETS VIRTUELS VARIABLES
Abstract:
(EN) A system comprises ATM switches (130G-130K) and a control module (160). The control module (160) communicates with the ATM switches via a first ATM switch (130) and a physical interface. A virtual connection extending between a first and second ATM switches has a bandwidth which is dynamically controlled by the control module (160). Virtual channels of a virtual path are selectively created or destroyed as needed. Customer contract and the time of the day are checked to determine whether the adjustment to certain parameters is permitted.
(FR) L'invention porte sur un système comprenant des commutateurs MTA (130G-130K) et un module de commande (160). Ce dernier (160) communique avec les commutateurs MTA via un premier commutateur MTA (130) et une interface physique. Une connexion virtuelle reliant un premier commutateur MTA à un deuxième présente une largeur de bande commandée dynamiquement par le module de commande (160). Des canaux virtuels d'un trajet virtuel sont créés ou détruits sélectivement selon les besoins. Une vérification des contrats des clients ainsi que des dates permet de préciser si l'ajustement à certains paramètres est autorisé.
