Abstract

Mobile IP has some performance degrade factors such as triangle routing and packet loss by the hand-off because the original IP was designed for the fixed network. The design goal for the next generation Internet service is to guarantee QoS. So, Mobile IP also should be able to provide the guaranteed QoS with performance enhancement because it is an IP-based mobile Internet service. In this paper, we propose route optimization, smooth hand-off scheme and MIP-LDP(Mobile IP-Label Distribution Protocol) on Mobile IP-over-MPLS framework to enhance the performance of the previously researched Mobile IP-over-MPLS schemes. The proposed framework enhanced long routing path problem and packet loss problem by the hand-off.

Mobile IP는 고정망을 대상으로 설계된 IP를 기반으로 하기 때문에 삼각라우팅과 핸드오프에 의한 성능 측면의 저하요인을 갖고 있다. 차세대 인터넷에서는 QoS 보장형 서비스 제공이 중요 연구방향이므로 Mobile IP를 기반으로 하는 이동성 인터넷 서비스도 성능 저하요인을 보완하고, QoS 보장형 서비스를 제공하기 위한 연구가 필요하다. 본 논문은 Mobile IP에서의 QoS 보장형 서비스의 제공을 위하여 라우팅과 QoS 보장형 서비스제공을 융합한 개념인 MPLS를 전달망으로 하는 Mobile IP-over-MPLS 프레임웍의 성능향상을 위한 경로 최적화(Route Optimization)와 유연한 핸드오프(Smooth Hand-off) 방식 및 이를 지원하기 위한 MPLS LSP 설정 프로토콜인 MIP-LDP(Mobile IP-Label Distribution Protocol)를 제안한다. 제안된 방식은 기존 Mobile IP-over-MPLS 서비스망에서의 긴 전송 경로 문제와 핸드오프로 인한 패킷 손실 문제를 개선하였다.
