Abstract

Existing mobility support scheme like MIPv4 has the delay at data transfer and Triangle routing problem. This paper proposes the new mobility support scheme and method that can overcome the problem using MPLS LSP in Next Generation Network. The proposed scheme overcomes the problem by introducing the LMS(Location Management Server) managing the location of the mobile terminal and the MPLS LSP between FA for a tunneling. We shows on the mathematical analysis using the queuing theory that this proposed scheme is more superior to the existing method(MIP).

MIPv4와 같은 기존의 이동성 지원 방안들은 데이터 전달에서의 지연 및 Triangle routing이라는 문제점을 갖고 있었다. 본 논문은 차세대 통합망 환경에서 MPLS (Multi Protocol Label Switching)의 LSP (Label Switched Path)를 이용하여 앞서 이야기한 문제점을 극복할 수 있는 새로운 이동성 지원 구조 및 방안을 제안한다. 제안된 구조는 이동 단말의 위치를 관리하는 LMS(Location Management Server)를 도입하여 이동 단말의 위치를 관리하고, FA 간 터널링을 위해 MPLS LSP를 도입함으로써 상기 문제들을 극복하였으며, 큐잉 이론을 기반으로 한 수학적 분석을 통해 기존의 방안(MIP 등)보다 우수함을 보인다.
