초록

본 논문은 측정에 근거한 연결 수락 제어에서 입력 트래픽에 따라 측정 반영 비율을 적응적으로 변화시키는 방식을 제안한다. 측정 반영 비율은 다음 갱신 기간에서 발생될 셀의 확률분포를 추정하는데 사용되는 파라미터이며 추정치와 측정치의 오차를 줄여 줄 수있다. 만약 측정 반영 비율이 고정적인 값이라면 다양한 서비스 품질을 요구하는 트래픽에 적용하기가 어렵다. 그러므로 본 논문에서는 추정치와 측정치의 차의 비율로 측정 반영 비율을 변화시켜서 추정 오차를 줄여주었다. 또한, 다양한 특성을 가진 트래픽이 다중화된 경우 각 트래픽 클래스체 대해서 개별 버퍼를 두어 다음 갱신 기간에서의 등가 대역을 적응적으로 추정하였다. 트래픽 클래스별 추정 등가 대역비에 따라 서비스를 수행하여 링크 효율을 높일 수 있었다.

This paper proposes the adaptive connection admission cotrol using the variale MRR(measurement reflection ratio) and the distribution of the number of cells arriving during the fixed interval. This distribution is estimated from the measured number of cells arriving at the output buffer during the fixed interval and traffic parameters specified by user. MRR is varied by the difference of estimated distribution and measurement distribution. As MRR is adaptively varied by estimated distribution error of accepted connections, it quickly reduces estimation error. Also, the scheduling scheme is proposed for multiplexed traffic with various traffic characteristics. For each traffic class, this scheme estimates adaptively equivalent bandwidth and schedules according to equivalent bandwidth ratio of each traffic class, so it improves cell loss rate and link utilization.
