CBR(Constant Bit Rate) 및 rt-VBR(Real Time Variable Bit Rate Traffic)을 포함한 실시간 서비스는 멀티미디어 애플리케이션의 급속한 확산으로 인해 점점 더 중요해지고 있습니다. 실시간 트래픽을 처리할 수 있는 셀 다중화 방법은 CTD(셀 전송 지연), CDV(셀 지연 변동), CLR(셀 손실률) 등 관련 QoS(서비스 품질) 요구 사항을 충족해야 합니다. 본 논문에서는 ATM 네트워크에서 실시간 및 비실시간 트래픽을 스케줄링하기 위한 LDBE(Longest Delay Beyond Expectation)라는 효율적인 셀 다중화 방법을 제시합니다. 실시간 트래픽의 경우 LDBE 방식은 특히 연결 경로를 따라 각 노드에 서로 다른 CDVT(CDV 허용 오차) 값이 적용될 때 CDV를 최소화하고 CLR 및 CTD를 줄일 수 있습니다. 시뮬레이션 결과는 제안된 LDBE가 실시간 트래픽에 대한 CLR, CDV 및 CTD 기준과 관련하여 다른 다중화 방법보다 더 나은 성능을 발휘한다는 것을 보여줍니다. 또한, 제안된 LDBE는 비실시간 가변 비트율(nrt-VBR)에 대해서는 낮은 CLR을 제공하고, UBR(Unspecified Bit Rate) 트래픽에 대해서는 CTD를 최소화함으로써 비실시간 트래픽을 스케줄링하는데에도 적합하다.

Abstract: Real-time services, including constant bit rate (CBR) and real-time variable bit rate traffic (rt-VBR), have become increasingly important owing to the rapid proliferation of multimedia applications. A cell multiplexing method capable of handling real-time traffic should satisfy related quality of service (QoS) requirements, including cell transfer delay (CTD), cell delay variation (CDV) and cell loss ratio (CLR). In this paper, we present an efficient cell multiplexing method, called longest delay beyond expectation (LDBE), to schedule real-time and non-real-time traffic in ATM networks. For the real-time traffic, LDBE scheme can minimize the CDV, and reduce the CLR and CTD, particularly when different CDV tolerance (CDVT) values are applied at each node along the path of a connection. Simulation results demonstrate that the proposed LDBE performs better than other multiplexing methods regarding these CLR, CDV and CTD criteria for real-time traffic. Furthermore, the proposed LDBE is also suitable for scheduling non-real-time traffic by providing a low CLR for non-real-time variable bit rate (nrt-VBR) and minimizing the CTD for unspecified bit rate (UBR) traffic.
