Abstract

In this paper, we proposed a new buffer management algorithm using perVC-Queuing discipline. Proposed algorithm uses service rate estimation and assigns dynamic perVC threshold to each VCs. Service rate estimation and dynamic perVC threshold combined with global threshold provide nearly optimal throughput and improve fairness performance of network resource among GFR VCs as well as guarantee MCR of all VCs. From simulation results, we demonstrate the proposed scheme fulfills the requirement of GFR service as well as improves the TCP throughput.

본 논문에서는 perVC-Queuing 기반의 버퍼관리알고리즘을 제안한다. 제안된 알고리즘은 서비스 율 측정과 동적 VC 임계치를 사용하여 GFR VC에 네트워크 자원을 공정하게 분배하고 모든 VC가 요구하는 MCR을 보장한다. 컴퓨터 시뮬레이션결과 제안된 알고리즘이 GFR 서비스 클래스가 요구하는 QoS를 보장하고 TCP의 성능을 향상하였다.
