nrt-VBR, ABR 및 UBR 트래픽과 같은 비실시간(NRT) 서비스는 데이터 애플리케이션을 위한 것입니다. NRT 서비스에는 셀 전송 지연 및 셀 지연 변화에 대한 엄격한 QoS 요구 사항이 없지만 ATM 네트워크는 셀 손실률(CLR), 버퍼 크기 요구 사항 및 서비스 공정성과 같은 우수한 성능을 보장하기 위한 다른 기준을 고려하면서 NRT 서비스를 제공해야 합니다. 서비스 공정성은 네트워크가 모든 연결을 공정하게 처리해야 함을 의미합니다. 즉, 도착률이 낮은 연결을 차별해서는 안 됩니다. 또한 연결의 버퍼 크기가 고정되어 있는 경우 연결 수명 동안 버퍼의 최대 셀 수를 줄이면 버퍼 오버플로로 인해 CLR이 낮아질 수 있습니다. 따라서 NRT 서비스를 제공하기 위한 셀 스케줄러를 설계할 때 이러한 기준을 최대한 고려해야 한다. 반면, 대부분의 기존 셀 스케줄링 방식은 일반적으로 하나의 성능 기준에는 적합하지만 다른 성능 기준에는 부적합합니다. 본 연구에서는 ATM 네트워크에서 NRT 서비스를 스케줄링하기 위해 버퍼 최소화 및 서비스 공정성(BMSF)이라는 새로운 셀 스케줄링 방식을 제시합니다. 확률 제약 조건을 사용하고 버퍼 크기가 가장 긴 연결을 먼저 선택하여 전송하면 BMSF는 최대 버퍼 크기 요구 사항, CLR 및 최대 버퍼 크기 및 셀 대기 지연 기준 측면에서 서비스 공정성과 관련하여 만족스러운 성능을 얻을 수 있습니다. 시뮬레이션 결과는 특히 NRT 서비스의 도착률이 다양한 경우 BMSF가 이러한 기준 측면에서 일부 기존 방식보다 더 나은 성능을 발휘한다는 것을 보여줍니다. 따라서, 본 명세서에서 제안하는 BMSF 방식은 ATM 네트워크에서 NRT 서비스를 실행 가능하게 스케줄링할 수 있다.

Abstract: Non-real-time (NRT) services such as nrt-VBR, ABR and UBR traffic are intended for data applications. Although NRT services do not have stringent QoS requirements for cell transfer delay and cell delay variation, ATM networks should provide NRT services while considering other criteria to ensure an excellent performance such as cell loss ratio (CLR), buffer size requirement and service fairness. Service fairness means that networks should treat all connections fairly. That is, connections with low arrival rates should not be discriminated against. In addition, given a fixed buffer size for a connection, reducing the maximum number of cells in a buffer during the lifetime of a connection can lead to a low CLR due to buffer overflow. Thus, these criteria should be considered as much as possible when designing a cell scheduler to provide NRT services. Whereas most of the conventional cell scheduling schemes are usually appropriate for one performance criterion, but inappropriate for another one. In this work, we present a novel cell scheduling scheme, called buffer minimized and service fairness (BMSF), to schedule NRT services in ATM networks. Using probability constraints and selecting a connection with the longest buffer size to transmit first allow BMSF to attain a satisfactory performance with respect to maximum buffer size requirement, CLR, and service fairness in terms of the maximum buffer size and cell waiting delay criteria. Simulation results demonstrate that BMSF performs better than some conventional schemes in terms of these criteria, particularly when NRT services have diverse arrival rates. Thus, the BMSF scheme proposed herein can feasibly schedule NRT services in ATM networks.
