초록

본 논문에서는 S-대역 위성/지상 겸용 다중빔 위성통신시스템에 적용을 위한 효율적인 기저대역 패킷 스위치 설계 방안을 제시하기 위하여 설계 요구사항과 고려사항들을 분석하고 기존의 기저대역 패킷 스위칭 기법들의 요소기술과 특성을 비교 분석하였다. 위성 기저대역 패킷 스위치의 설계 요구사항 정립을 위하여 기저대역 패킷 스위치의 요구기능, 시스템 규격, 통신서비스 종류와 성능요구사항을 분석하였고, 기존의 레이어-2 및 레이어-3 패킷 스위치 특성, 스위칭 프로토콜 특성, 패킷 스위치 구조 특성들에 대한 비교 분석 결과를 기반으로 MPEG 기반의 레이어-2 위성 기저대역 패킷 스위치의 하드웨어 설계 방안을 제시하였다.

In this paper, we present an efficient design scheme based on analysis of design requirements and considerations of baseband packet switch for S-band satellite/terrestrial hybrid multi-beam satellite communication systems. To establish design requirements and considerations, we analyze required functions of baseband packet switch, specifications of multi-beam satellite communications, communication services and performance requirements. And also we analyze and compare conventional layer-2 and layer-3 satellite baseband packet switching techniques, packet switching protocols and packet switch architectures, to apply from analyzed results. Finally, we propose a hardware design scheme of MPEG based layer-2 baseband packet switch using analyzed results.
