초록
스마트 폰의 등장과 보급 및 급격한 확산은 정보통신 분야에서 새로운 트랜드를 주도하고 있다. 이러한 흐름 아래IETF와 3GPP에서는 대규모의 모바일 인터넷 트래픽을 효율적으로 처리하기 위하여 분산 이동성 관리(DMM: Distributed Mobility Management) 기술에 대한 표준화 작업을 진행 중에 있다. 본 논문에서는 IETF와 3GPP에서의 여러 분산 이동성 관리 기법들을 조사하여 분산 이동성 관리의 연구 동향을 알아보는 한편 각각의 이동성 지원 방안을 3가지 범주(호스트 기반, 네트워크 기반, 라우팅 기반 분산 이동성 관리)로 분류하여 설명하고자 한다. 또한 기존분산 이동성 관리 연구의 동향 분석을 토대로 새로운 라우팅 기반 분산 이동성 관리 기법을 제안하고 이를 기존의 이동성 관리 기법들과 정성적으로 분석하여 이의 결과를 제시한다.
Abstract
As smart phone has rapidly proliferated over the past few years, it leads to new trend in data communication. Along with this, standards development organizations such as IETF and 3GPP are doing to standardize DMM (Distributed Mobility Management) approach to handle excessive mobile data traffic efficiently. In this paper, we survey different approaches for DMM in IETF and 3GPP by focusing on three different DMM approaches (Host-based, network-based, and routing based DMM). Based on analysis for these DMM approaches, we propose a routing based-DMM approach and provide a qualitative analysis to compare the existing mobility management approaches and proposed DMM approach.
