P2P 시스템의 주요 이슈는 자원 (resource) 을 효율적으로 저장하고 찾는 것이다. 자원 탐색 프로토콜은 초기의 Napster, Gnutella와 같은 형태에서 발전하여, 현재는 분산 해시 테이블 (Distributed Hash Table을 사용한 형태로 발전하고 있다. 본 논문에서는 분산 해시 테이블을 사용한 P2P 프로토콜인 Magic Square를 제안한다. Magic Square에 참여하는 칵 노드는 양방향 스킬리스트로 구성된 지역 라우팅 테이블과 임의의 노드로 구성된 전역 라우팅 테이블을 가진다. 지역 라우팅 테이블은 각 노드의 능력을 고려하여 구성된다. 스킵리스트를 사용하였기 때문에 탐색과 노드의 추가라 삭제 과정이 간단하며. P2P 네트워크가 자주 바뀌어도 큰 영향을 받지 않는다.
