Récemment, le trafic de communications en temps réel telles que la vidéo ou la téléphonie IP a augmenté sur Internet. Un faible délai et une faible gigue de communication sont nécessaires pour exécuter ce type de services en douceur. Le système CoS (Class of Services) qui contrôle le trafic par unité de classe telle qu'une application fait actuellement l'objet d'une attention particulière. Il est considéré comme un mécanisme de contrôle efficace qui utilise les caractéristiques du trafic Internet. L'une des méthodes efficaces de contrôle des files d'attente pour réaliser le CoS est le CBQ (Class Based Queueing). Une allocation de bande passante efficace et dynamique peut être réalisée en utilisant CBQ. Cependant, le mécanisme CBQ n’est pas nécessairement efficace pour la communication en temps réel. Dans cet article, nous clarifions l'effet du schéma de contrôle dynamique CBQ sur la communication en temps réel par expérience. De plus, nous montrons qu’une communication à faible délai et à faible gigue est possible en réduisant les frais de contrôle inutiles causés par le changement de trafic. Nous proposons un nouveau mécanisme qui modifie l'allocation de bande passante du CBQ en supprimant dynamiquement le trafic non temps réel et en donnant la priorité au trafic en temps réel lors de l'utilisation de la bande passante. Nous montrons également son efficacité en utilisant un système réel.

Abstract: Recently, traffic of real-time communication such as video or IP telephony is increasing in Internet. Low delay and low jitter communication is required to perform these kinds of services smoothly. CoS (Class of Services) scheme which controls traffic by the class unit such as application is currently being paid attention. It is considered to be efficient control mechanism which utilizes characteristics of Internet traffic. One of effective methods for queueing control to realize CoS is CBQ (Class Based Queueing). Efficient and dynamic bandwidth allocation can be realized by using CBQ. However, CBQ mechanism is not necessarily efficient for real-time communication. In this paper, We clarify the effect of dynamic CBQ control scheme on real-time communication by experiment. In addition, we show that low delay and low jitter communication is possible by reducing unnecessary control overhead which is caused by traffic change. We propose new mechanism which changes bandwidth allocation of CBQ dynamically suppressing non real-time traffic and giving priority to real-time traffic on using bandwidth. We also show its efficiency by using real system.
