본 논문은 P2P 네트워크에서 어플리케이션 레벨의 영속성있는 저장 시스템에 대해서 살펴본다. 인터넷 클라이언트의 성능 향상과 인터넷 접속 기술의 발달로 Peer-to-Peer (P2P)라는 키워드로 대표되는 다양한 파일 저장, 검색, 공유 어플리케이션이 소개되었다. 그러나, 기존의 서버 기반의 분산 저장 방식은 xDSL 기반의 가변 IP 기반의 현재 인터넷 환경에서 불안정한 성능을 보이고, 파일을 저장하고 나서 검색 발견의 확률이 떨어지는 문제점을 가진다. 본 논문에서는 시스템의 가용성(Availability)을 높이기 위한 파일의 분할 저장, 중복 저장 방법을 소개하고 이의 효과를 분석해 보인다.
