초록

본 논문에서는 ATM 계층에서 GFR 서비스의 공정성 기준을 만족시키고, 효율적인 셀 서비스를 위한 버퍼관리 및 스케줄링 기법을 제안하였다. 시뮬레이션을 통한 성능 분석 결과 기존의 WRR 방식에서 만족하지 못하는 공평성 기준 2(MCR plus equal share)를 만족시킬 수 있었다. 또한 수율면에서도 제안된 알고리즘이 기존의 WRR보다 약 29% 향상되었고 공평성 지표에서는 WRR보다 제안된 알고리즘이 더 우수함을 확인할 수 있었다.

In this paper, we proposed a new buffer management and cell scheduling scheme for GFR service in ATM networks. The proposed scheme is able to satisfy fairness criteria and efficient cell service in GFR. Performance analysis through the simulation presents that the proposed scheme can meet fairness 2(MCR plus equal share), which are not met by conventional scheduling mechanisms such as WRR. Also, the proposed scheme is superior to WRR about 29% in throughput and more efficency in fairness criteria.
