Abstract

차세대 광 인터넷 백본망 기술은 WDM(Wavelength Division Multiplexing)기반의 고속 대용량 전광 전달망인 AOTN (All-Optical Transport Network)으로 발전하고 있고, 가입자의 원활한 멀티미디어 서비스의 제공을 위한 망 생존성 보장이 중요한 이슈로 부각되고 있다. 특히 광소자의 고유한 특성을 교묘히 이용하는 물리적 공격은 AOTN의 투명한 데이터 전달 특성으로 인해 기존의 오버헤드를 이용한 관리 시스템이 더 이상 유효하지 않아, 새로운 검출/회복 메커니즘이 요구된다. 본 고에서는 AOTN에서 발생 가능한 공격 유형을 광소자별로 분석하고, 광 레벨에서의 공격 검출과 회복 메커니즘을 소개한다. 이를 바탕으로 공격관리 시스템(Attack Management System: AMS)의 제어 모델을 기술한다.
