Abstract

L'invention concerne un procédé permettant de réguler une surcharge dans un réseau à commutation par paquets, en particulier, un réseau mobile ou sans fil dans lequel on utilise le protocole de commande de transmission (TCP) comme protocole de couche de transport. On ajoute des informations de notification d'encombrement à un paquet de données qui suit un paquet de données perdu à cause d'un débordement de tampon. Cela constitue une manière efficace d'améliorer le fonctionnement du protocole TCP dans des réseaux mobiles ou sans fil, du fait qu'il est possible d'agir sur l'encombrement de façon totalement indépendante des retransmissions. Le mécanisme proposé constitue une manière simple de mise en place de stratégies de régulation permettant d'éviter l'encombrement du protocole TCP dans des réseaux mobiles ou sans fil. En outre, les informations de notification de congestion doivent être ajoutées au moins avant d'excéder un nombre seuil de paquets suivants de façon à fixer la cadence du déclenchement de la régulation de l'encombrement et de la récupération des pertes dues à l'encombrement.
