Abstract

This paper examined the performance of differentiated services applied to each different traffic. For this purpose, we used three traffics which have a different quality of service and generate packets from a specific source to destination. To allocate a proper code point according to QoS, a common policy which is the simple policy model of time sliding window with 3 color marking (TSW3CM) was established to each traffic. To evaluate the performance, we investigate and compare code points to each traffic. Simulation results using NS-2 showed that the code points 10, 11, and 12 can be differently allocated to each traffic according to its sending rates 1Mbps, 2.5Mbps, and 4Mbps.

본 논문에서는 개별 트래픽에 적용된 차등화 서비스의 성능을 고찰하였다. 이를 위해 QoS 특성이 다르고 특정 송신원에서 수신원으로 향하는 패킷들을 발생시키는 세 개의 트래픽을 사용하였다. 각 트래픽에는 서비스 품질에 따라 적절한 코드 포인트를 할당하기 위해서 간단한 3 색 표식을 갖는 타임 슬라이딩 윈도우의 정책 모델을 공통의 정책으로 적용시켰다. 성능 평가를 위해 개별 트래픽에 대해서 코드 포인트를 조사하여 비교하였다. NS-2를 이용한 실험 결과 각 트래픽의 전송속도 1Mbps, 2.5Mbps, 4Mbps에 따라 차등적으로 코드 포인트가 10, 11, 12로 할당됨을 확인할 수 있었다.
