제안된 큐 서비스 방식을 이용하여 연결 수락 제어는 트래픽 왜곡의 영향을 계산할 수 없는 트래픽 왜곡의 영향이 실재로 존재한다는 가정 하에 트래픽 왜곡에 대한 영향에 종단간 지연을 보장함으로 서 연결 수락 가능 범위를 다양한 프레임의 길이에 대해 나타내었으며, 프레임의 길이가 클수록 제안된 큐 서비스 방식의 연결 수 락 범위가 지연 EDD방식과 비교해서 많은 차이를 보이지만 프레임의 길이를 점차 줄여갈수록 연결 수락 가능 범위가 지연 EDD 방식에 근접함을 나타내었다.

(English Abstract) |
We propose a cell－multiplexing scheme for the real－time communication service in ATM network and a new service discipline guarantee end-to-end delay based on pseudo-isochronous cell switching. The proposed scheme consists of two level frame hierarchy, upper and lower frame, which is used to assign the bandwidth and to guarantee the requested delay bound, respectively. Since the Proposed algorithm employs two level frame hierarchy, it can overcome the coupling problem which is inherent to the framing strategy It can be comparatively reduce the complexity, and still guarantee the diverse delay bounds of end-to-end. Besides, it consists of two components, traffic controller and scheduller, as the imput traffic description model and regulates the input traffic specification. The function of the traffic controller is to shape real -time traffic to have the same input pattern at every switch along the path. The end-to-end delay is bounded by the scheduller which can limit the delay variation without using per-session jitter controllers, and therefore it can decrease the required buffer size. The proposed algorithm can support the QoS's of non-real time traffic as well as those of real time traffic.
