네트워크 장비에서 동작하는 소프트웨어의 버그 수정이나 새로운 기능 추가를 위해서 소프트웨어를 업그레이드할 필요가 있다. 하지만 서비스 중인 소프트웨어를 업그레이드하기 위해서는 네트워크 서비스를 종료한 후에 소프트웨어를 업그레이드해야만 하는 문제가 있다. 이러한 문제를 해결하기 위해서 서비스 중 소프트웨어 업그레이드(ISSU : In-Service Software Upgrade) 기술이 사용된다. ISSU는 네트워크 장비를 오프라인 시키거나 네트워크 서비스를 중단하지 않고 소프트웨어를 업그레이드하는 기술이다. 본 논문에서는 무중단 네트워킹 서비스를 제공하기 위해서 ISSU 기술을 네트워크 OS에 적용하는 방법을 제안하고 구현한다. 본 논문에서는 고가용성 기능을 가지고 있는 한국전자통신연구원에서 개발한 N2OS를 이용하였다. 또한 ISSU 기능이 정상적으로 동작함을 검증하기 위해서 가상 머신 기반의 시험 환경을 만들고 시험을 진행하였다.
