웹 서비스 응답성능 개선을 위한 Linux TCP RTO_MIN 변수 자동조정에 관한 연구

초록

TCP web services using Linux systems have been used in a variety of areas in Internet and LAN environments. Most Linux devices operate by default system parameters. To optimize system performance, expertise in monitoring Linux operating system variables and service performance is required and at the same time network analysis needs to be performed. TCP performance is highly affected by RTT, and Linux's operating system variable, the TCP retransmission parameter RTO_MIN, is fixed at 200 msec. A fixed 200msec RTO_MIN on a recently high-speed network does not fit the user's environment. we develop a system that automatically adjust RTO_MIN to improve TCP web service performance. Through the experiments, it is confirmed that the proposed system automatically adjusts RTO_MIN value to improve the system performance.
