초록

CBR 소스 트래픽에 대한 ATM 교환기와 광대역 망종단장치의 셀전달지연을 측정하여 국내영역에서의 셀전달지연을 추정하였다. 추정결과 I.356의 할당원칙에 의한 국내영역의 셀전달지연 목표치를 만족하였다. Chernoff 누적방법에 기초한 peak to peak CDV 할당방법을 제안하고 국내영역의 노트들에 적용하였다. 수치해석 결과 전송경로상에 놓인 노드수와 각 노드에서의 CDV가 증가하는 경우에 제안된 할당방법이기존의 균등할당 방법에 비해 정확도가 개선되었다.

When CBR source traffics are loaded to ATM switch and broadband network termination, CTD values of ATM switch and broadband network termination are measured and then the values of CTD in the domestic region arc estimated. The estimation values of CTD satisfy the objective of CTD in the domestic region allocated by allocation rules of 1.356. The peak-to-peak CDV allocation method based On Chernoff accumulation method is proposed and applied to the nodes of national portion. From the result of numerical analysis, the proposed method is more accurate than the equal allocation method for peak -to-peak CDV in case that the CDVs at each node and the number of ATM nodes on the path increase.
