초록

본 논문에서는 모바일 중심의 미래 인터넷을 위한 Mobile-Oriented Future Internet (MOFI) 구조를 소개하고, 호스트 Identifier(ID)와 Locator(LOC)의 분리를 토대로 설계된 MOFI 구조에서 ID와 LOC의 분산형 매핑 제어 기법을 제안한다. 제안하는 Dynamic and Distributed Mapping System (DDMS) 기법에서는 ID와 LOC의 매핑 기능을 각 도메인의 Access Router(AR)에 분산시킴으로서 기존의 Proxy Mobile IP (PMIP) 프로토콜의 중앙집중형 방식의 문제점을 개선하였다. 성능 분석을 위해 리눅스 플랫폼에서 MOFI 구조와 제안하는 매핑 제어 기능을 구현하였고, 테스트베드 실험을 통해 기존 PMIP에 비해 제안 기법이 데이터 전송 측면에서 더 효율적임을 확인하였다.

In this paper, we discuss a new architecture of future Internet for mobile-oriented environments, named Mobile-Oriented Future Internet (MOFI). The MOFI architecture is designed with Host Identifier and Local Locator (HILL) for identifier and locator separation. Based on the HILL separation architecture, we propose a Dynamic and Distributed Mapping System (DDMS) for identifier-locator mapping control. In DDMS, the mapping control function is distributed onto each access router in the domain, which is different from the centralized approach using a central anchor. For validation of the proposed MOFI-DDMS architecture, we implemented the data delivery and mapping control functions using Linux platform. From the testbed experimental results, we see that the DDMS architecture can give better performance than the existing Proxy Mobile IP (PMIP) protocol in terms of data transmission throughput.
