Abstract

In this paper, we propose a method of monitoring traffic and analyzing information of handover in mobile IPv6 networks. Our proposed method analyzes handover latency through monitoring packets at routers without installing monitoring applications at mobilenodes. For this purpose, we employ a flow-based traffic monitoring standard called IPFIX to perform the traffic measurement function the packets at the routers. Therefore, our method is useful in that we could easily obtain information regarding handover of mobile nodes by only monitoring traffic at the routers. In order to verify the proposed method, we carried out experiments in a real 802.11-based mobile IPv6 network testbed. From our experimental results, it was shown that the calculated handover latency for uploading traffic is accurate with less accuracy of analyzing the handover latency for downloading traffic.

본 논문에서는 모바일 IPv6 망에서 트래픽을 모니터링하고 사용자의 이동성 정보를 분석하는 방법을 제안한다. 제안하는 방법에서는 트래픽 모니터 링을 위한 별도의 소프트웨어를 단말에 설치하지 않고 라우터에서 패킷들을 모니터링하여 핸드오버 지연시간을 분석한다. 라우터에서 플로우 기반 트래픽 모니터링을 수행하기 위하여 표준 플로우 기반 트래픽 모니터링 방법인 IPFIX를 사용한다. 따라서, 단말과 상관없이 라우터에서의 모니터링만으로 사용자의 이동성에 대한 정보를 분석할 수 있는 장점을 가진다. 제안한 방법을 검증하기 위하여 실제 구축된 802.11 기반의 모바일 IPv6 망에서 이동성 실험을 수행하여 핸드오버를 측정하고 분석하였다. 실험을 통하여 분석된 결과 다운로드의 핸드오버 지연시간 측정 결과는 약간의 오차를 포함하였지만, 업로드의 핸드오버 지연시간 측정은 정확한 결과를 보여주었다.
