Abstract

In this paper, we proposed new buffer management and cell scheduling scheme of GFR service for improving fairness of TCP/IP traffic in ATM networks. The proposed algorithm used untagged cell, which came to ATM switch, to decide the policy for discard of frame and what kind of VC cell it would serve. Performance analysis through the simulation present that proposed scheme can meet fairness 2 (MCR Plus equal share), which are not met by conventional scheduling mechanism such as WRR. Also, proposed scheme is superior to WRR about 30% in throughput and more efficiency in fairness criteria.

본 논문에서는 ATM 계층에서 TCP/IP 트래픽 공평성 향상을 위한 GFR 서비스의 버퍼관리 및 스케줄링 기법을 제안하였다. 제안된 알고리즘은 프레임의 폐기정책 뿐만 아니라 여러 VC중에서 어떠한 VC의 셀을 서비스 할 것인가를 결정하기 위해 ATM 스위치에 도착하는 untagged 셀을 이용하였다. 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 30% 향상되었고 공평성 지표에서는 WRR보다 제안된 알고리즘이 더 우수함을 확인할 수 있었다.
