초록
본 논문은 유무선 통합 환경 및 이동통신망에서 발생할 수 있는 TCP 프로토콜의 전송성능 저하요인과 문제점에대해서 분석하고 이를 개선하기 위한 방안을 제안한다. 이를 위하여 기존의 TCP 성능 개선방안들을 학술 분야, 표준분야 및 상용제품 분야 면에서 분석하여 TCP 전송속도 가속화 기술에 대한 동향을 정리한다. 이를 토대로 본 논문에서는 기존 통신망의 Radio Access Network(RAN), Core Network(CN), Internet Service Provider(ISP),Application Service Provider(ASP) 및 단말의 수정이 없이 TCP의 성능을 개선하는 방안을 제시한다. 제안한 방안의 성능 평가가 NS2 시뮬레이터를 통하여 이루어졌으며 제안한 방안의 성능을 기존의 TCP, Snoop, Snoop + FAST TCP 방안과 비교하였다. 성능 평가 비교 결과, 제안한 방안은 기존 방안들 대비 우수한 성능을 제공하면서 보다 용이하게 기존 이동통신망 및 유무선 통합 네트워크 환경에 적용할 수 있음을 보였다.
Abstract
In this paper, we review the potential problems and its effect for TCP performance degradation on 3G cellular network and Fixed Mobile Convergence (FMC) networks. Then we survey conventional methods to improve the TCP performance in view of academical approaches, standards and products. To achieve the goal,we propose a network reference model with new devices which provide enhanced TCP performance without modification for conventional devices such as end-user device (Note PC, Phone, etc.), RAN/CN, IP Network,and ASP/ISP application servers. We evaluate the performance of the proposed method using NS2 simulator. Also, we compare the performance with conventional methods such as original TCP, Snoop, FAST TCP +Snoop. Then, we show that the proposed method provides a superior performance than conventional schemes,and it is an easy and cost effective way to improve the performance of TCP for FMC networks.
