향후 인터넷 기반 애플리케이션에는 확장성, 보안 및 신뢰성, 새로운 서비스에 대한 유연성 및 QoS 등의 요구사항이 제시된다. 기존 클라이언트-서버 방식에서 이러한 요구사항의 만족을 위해서는 복잡성 및 고비용 문제가 제기된다. 반면, 모든 형태의 분산 자원 접근이 가능한 P2P 통신 방식에서는 보다 간단한 해결방안을 제시함으로써 인터넷 기반 애플리케이션에 새로운 가능성을 제시하고 있다. 본 고에서는 P2P 기술에 대한 연구 개발 및 응용 서비스 동향에 대해여 소개한다. 또한 유비쿼터스 환경에서 P2P 기술의 역할 및 해결되어야 할 문제점에 대해서 정리하고, 실제 P2P를 이용한 유비쿼터스홈 구축 모델을 제시한다. 마지막으로 향후 P2P 요소 기술 및 응용서비스 발전 전망에 대해 간략히 살펴본다.
