초록

ATM과 IP 망에서 혼잡발생시 높은 우선순위를 가진 패킷은 낮은 우선순위를 가진 패킷에 비해 영향을 적게 받도록 설계되어야 한다. 이러한 문제 해결을 위해, 본 논문에서는 기존 If 망에서 사용되는 가중치 CSFQ(Weighted Core-Stateless Fair Queueing)를 ATM 노드의 공간 우선순위(space priority) 정책에 적용하였다. 성능분석을 위해 임계치(threshold)를 갖는 MMPP/D/1/K 큐잉모델의 트래픽 클래스별 셀 손실률을 유도하고 그 결과를 논하였다. 분석결과를 통해 가중치 CSFQ 기법이 ATM 혹은 IP 노드에서 차별화된 서비스 제공에 매우 유용함을 보였다.

In ATM and W networks, high Priority Packets should be selectively favored over low Priority Packets in case of congestion. For this purpose, we introduce a space priority policy for ATM nodes in this paper which is very similar to the weighted core-stateless fair queueing(WCSFQ) in IP nodes. We also analyze the loss probabilities for different classes of cells for MMPP/D/1/K with a threshold level, and discuss the numerical results. The numerical results illustrate that the WCSFQ scheme can be used to support the differentiated services in ATM or IP nodes.
