최근 인터넷에서는 영상이나 IP 전화 등 실시간 통신 트래픽이 증가하고 있다. 이러한 종류의 서비스를 원활하게 수행하려면 지연과 지터가 낮은 통신이 필요합니다. 현재 애플리케이션 등 클래스 단위로 트래픽을 제어하는 CoS(Class of Services) 방식이 주목받고 있다. 이는 인터넷 트래픽의 특성을 활용한 효율적인 제어 메커니즘으로 평가된다. CoS를 구현하기 위한 효과적인 큐잉 제어 방법 중 하나는 CBQ(Class Based Queueing)입니다. CBQ를 사용하면 효율적이고 동적인 대역폭 할당을 구현할 수 있습니다. 그러나 CBQ 메커니즘은 실시간 통신에 반드시 효율적인 것은 아닙니다. 본 논문에서는 실험을 통해 동적 CBQ 제어 방식이 실시간 통신에 미치는 영향을 명확히 한다. 또한, 트래픽 변화로 인해 발생하는 불필요한 제어 오버헤드를 줄임으로써 저지연, 저지터 통신이 가능함을 보여준다. 우리는 비실시간 트래픽을 동적으로 억제하고 대역폭 사용 시 실시간 트래픽에 우선순위를 부여하는 CBQ의 대역폭 할당을 변경하는 새로운 메커니즘을 제안합니다. 또한 실제 시스템을 활용하여 효율성을 보여줍니다.

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.
