Abstract: 본 발명은 구조적 Ｐ2Ｐ 네트워크를 위한 데이터 매핑 방법 및 장치에 관한 것으로, 산술 매핑 기법을 사용하여 사전적 순서를 파괴하지 않으므로 복잡한 쿼리를 지원할 수 있음은 물론이고, 심볼들의 출현 빈도 확률을 알고 있는 경우에는 데이터가 균등하지 않은 경우에도 데이터를 키로 균일하게 매핑하므로 별도의 로드밸런싱을 하지 않거나 그 오버헤드를 최소화 할 수 있는 이점이 있다.

Abstract: PURPOSE: A data mapping method and apparatus thereof are provided to minimize overhead without load balancing by mapping data through a key and to support a complicate query. CONSTITUTION: A data input unit(110) receives a data space. An arithmetic mapping unit(120) converts data space into a key space by using an arithmetic mapping scheme. A key distributor(130) distributes peer nodes of a structural P2P network(140). The arithmetic mapping unit converts a data space into a key space.
