A New Consolidation Algorithm for Point-to-Multipoint ABR Flow Control in ATM Networks

ATM망에서 점대 다중점 ABR 흐름 제어를 위한 새로운 통합 알고리즘

In this paper, we propose a new consolidation algorithm for point-to-multipoint ABR flow control and compare the performance of the proposed algorithms with that of an existing consolidation algorithm. We first investigate problems of the existing algorithm in consolidating backward RM cells and propose two new consolidation algorithms to resolve these problems. Also, we investigate the performance of the proposed algorithms by simulation. As results, we show that the proposed algorithms exhibit a better performance than the existing algorithm in terms of ACR, queue length, utilization, and fairness.
