Abstract

In order to solve the problems such as overload, single point of failure, non-optimized data path, and network scalability in conventional central mobility management protocols, distributed mobility management schemes have been continually studied in and around the IETF. In this paper, a network-based partially-distributed mobility management mechanism, pDMMv6, is suggested and the performance comparison with traditional protocols such as PMIPv6 and MIPv6 is made through simulation under the various user traffic environment. The simulation results include UDP packet delivery ratio, end-to-end packet delay, binding delay for registration signaling, CPU utilization in each node, and response delays in several server-client TCP applications such as web browsing, e-mail, telnet remote login, FTP file up/down-load, and database access.

과부하 및 단일장애점(Single Point of Failure), 경로 비최적화, 망 확장성 등의 문제점을 가지고 있는 기존 중앙 집중형 이동성 관리 프로토콜들의 문제점을 해결하기 위해 최근 IETF를 중심으로 분산 이동성 관리 방안이 활발히 연구되고 있다. 본 논문에서는 망기반 부분분산형 이동성 관리 메커니즘 pDMMv6를 제시하고, 시뮬레이션을 통해 다양한 사용자 트래픽 환경에서 기존의 PMIPv6 및 MIPv6 프로토콜과의 성능 비교를 수행하였다. 성능분석 결과로는 UDP 트래픽의 전송율, 단대단 패킷 전송지연시간, 신호 메시지 바인딩 지연시간, 노드별 CPU 점유율 및 다양한 서버-클라이언트 TCP 응용에 따른 응답시간(웹 브라우징, 이메일 송수신, 텔넷 원격접속, FTP 파일전송, 데이터베이스 액세스 등)들을 제시하였다.
