Abstract

L'invention concerne un procédé et un dispositif de contrôle de trafic, et un support de stockage informatique. Le procédé de contrôle de trafic est appliqué à un dispositif de contrôle de trafic. Le procédé comprend les étapes consistant à : acquérir respectivement une vitesse d'écriture V1 d'une extrémité d'envoi, une vitesse de lecture V2 d'une extrémité de réception, une vitesse d'émission V définie par un utilisateur et une capacité L d'une file d'attente de données d'une zone d'antémémoire du dispositif de contrôle de trafic lui-même et une capacité utilisée E de la file d'attente de données ; et, en fonction de la vitesse d'écriture V1, de la vitesse de lecture V2, de la vitesse d'émission V, de la capacité L et de la capacité utilisée E, commander le temporisateur de démarrage et le temporisateur d'arrêt pour que l'extrémité d'envoi écrive des données dans la zone d'antémémoire et/ou commander le temporisateur de démarrage et le temporisateur d'arrêt pour que l'extrémité de réception lise des données dans la zone d'antémémoire.
