초록

비동기식전송모드망에서 선입-선출은 각 연결들이 요구하는 다양한 서비스 품질을 보장하기 어렵다. 따라서 각 VC에 확실한 대역폭 할당을 통해 요구하는 QoS를 보장하는 트래픽 분리 기법에 제안되었다. 본 논문에서는 이러한 목적을 위해 VC 단위의 “주기적토큰-기반 조절기”를 사용하는 흐름제어 셀 다중화기를 제안한다. 제안된 다중화기는 재가-conserving 성질을 유지하면서 VC 트래픽 분리를 실현하게 된다. 먼저 제안된 다중화기의 우수한 주요 성질을 논하고 시뮬레이션을 통해 출력 트래픽 스트림 특성과 각 VC의 트래픽의 분리 특징을 분석한다.

Since First-Come-First-Served discipline makes it difficult to satisfy the diverse quality of scrvicc(QoS) requirements for each c-oonection, traffic isolation has been proposed for guaranteeing the desired QoS through explicit bandwidth allocation to each virtual connection(VC) in A TM networks. For this purpose, we propose a rate-controlled cell multiplexer using a simple "periodic token-based regulator" per- Vc. The proposed multiplexer realizes VC isolation, while still operating work'||'&'||'not;conservingly. We first discuss its major properties, and then examine its features with respect to the characteristics of the output traffic streams and the traffic isolation of individual VC's, by simulation.n.
