ATM 망에서 조기 공정률 할당 알고리즘에 관한 연구 = A Study on the Early Fair Rate Allocation Algorithm in ATM Networks

다국어 초록 (Multilingual Abstract)

In this paper, a EFRA+(early fair rate allocation) algorithm is proposed for ATM switches supporting ABR service. The central issue of explicit rate control algorithms for ABR service is the computation of max-min fair rates for every connection. The EFRA+ inherits the main feature of the EFRA and enhances the computation method of max-min fair rate. Thus, the EFRA+ computes the max-min fair rates with O(1) computational complexity more accurate than EFRA. This exact calculation of fair rates expedites offers excellent transient response and improves the performance decay of the EFRA at the transient state. At the steady state, the EFRA+ operates without causing any oscillations in rates and is very robust in various ATM networks. The ABR queue length at the buffer can further be reduced without any degradation in throughput. By using computer simulation, it is compared EFRA+ with existing algorithms such as EFRA and is demonstrated the effectiveness of the EFRA+ algorithm.
