Abstract

We have solved a problem occurring in case that RSVP is applied to existing wired network in order to guarantee a QoS of multimedia traffic in mobile computing environment in this paper. If MN moves to another area when Mobile IP is applied to RSVP, HA makes new tunnel to FA because SESSION ID of MN is changed. However, we suggest MIP-DUDN method, which applied RSVP. Although MN moves to another area in this method, it does not make new tunnel because it eliminates the problem of existing Triangle Routing Problem. We design the new protocol of RMIP-DUDN and compare with the method of existing Mobile IP applied to RSVP.

본 논문에서는 이동 컴퓨팅 환경에서 멀티미디어 트래픽의 QoS를 보장하기 위해 유선 환경에서 사용되고 있는 RSVP를 이동 컴퓨팅 망에 적용 시 나타나는 문제점을 해결한다. RSVP를 Mobile IP에 적용 시 MN이 다른 지역으로 이동을 한다면 MN의 세션 ID가 변경되기 때문에 HA는 FA로 새로운 터널을 만든다. 그러나 본 논문에서는 기존의 Mobile IP에서 나타나는 삼각 라우팅 문제를 제거함으로써 MN이 다른 지역으로 이동을 하여도 새로운 터널을 만들지 않는 RMIP-DUDN(RSVP가 적용된 MIP-DUDN) 방법을 제안한다. 새로운 RMIP-DUDN의 프로토콜을 설계하고, 기존의 Mobile IP에 RSVP를 적용한 방법과 비교 평가한다.
