Abstract

Diff-Serv is a mechanism by which network service providers can offer differing levels of network service to different traffic, in so providing quality of service (QoS) to their customers. Because this mechanism has been deployed just for fixed hosts with the Token Bucket mechanism, DiffServ have been suggested can not satisfy the mobility service or the differential serrlce for Individual traffics. In this paper, we suggest WFQ mechanism for traffic conditioner and scheduling method for monitoring the AggF(Aggregate Flow) which will be controlled in edge nodes and border routers. So it will control traffic rate dynamically and suggest efficient usability of bandwidth.

Diff-Serv는 개별적으로 구분된 다른 트래픽에 대해서 다른 종류의 네트워크 서비스를 제공하기 위한 메카니즘이며 이용자들에게 양질의 서비스를 제공하기 위한 방법을 제시하고 있다. DS는 토큰 버켓 방법을 사용하여 고정된 호스트들에게 제공되기 때문에 이동성을 가지는 서비스나 개별적인 트래픽에 대한 차등적인 서비스를 제공할 방안이 존재하지 않는다. 본 논문에서는 트래픽컨테이너(TC)를 위해서 WFQ 방법과 변방 노드들과 경계 라우터들 내부에서 제어가 가능한 AggF(Aggregate Flow)를 모니터링하여 스케쥴링하는 방법을 제시한다. 이 방법은 트래픽 비율(traffic rate)을 유동적으로 제어가 가능하며 대역폭의 효율적인 이용성을 제공하고 있다.
