Abstract

Recently, many researches focus on Ubiquitous Network which comprised various networks for effective service provision. In particular, OSGi proposed by OSGi Alliance is preferred for core infrastructure to establish Ubiquitous Network as it supports integration and inter-operation among various service environments, and dynamic configuration of services. However, OSGi is limited to be used only within local service framework, since OSGi specification does not have any considerations for inter-operations between internal and external services. Thus, in this paper we propose JARSIO(JAva Remote Service Invocation for OSGi) framework which enables the inter-operations of dynamic internal OSGi services and other external services. The proposed framework is based on the TCP/IP protocol, and provides effective mechanisms for the inter-operations of the services.

최근 다양한 네트워크 기술들을 통합하고 하나의 단일화된 유비쿼터스 네트워크를 형성하여 사용자에게 효과적으로 서비스를 제공하려는 기술적 시도들이 많이 이루어지고 있다. 특히, OSGi Alliance에서 제안된 OSGi는 자바기술을 기반으로 서비스의 동적 재구성을 지원함으로써 다양한 미들웨어 환경 사이에서 서비스간의 상호연동 및 유비쿼터스 네트워크 구성을 위한 핵심 인프라로서 많이 활용되고 있다. 그러나 현재 OSGi 표준에서는 내부에 등록된 서비스를 외부환경에서 공개(publish)하고 호출 및 연동하기 위한 메커니즘을 정의하고 있지 않아, 분산 환경에서 효율적인 서비스의 동적 재구성 및 협업을 달성하는 데에 다소 어려움이 있다. 따라서 본 논문에서는 OSGi 환경에서 등록된 서비스들의 효율적인 서비스의 공개 및 연동을 위한 JARSIO(JAva Remote Service Invocation for OSGi) 프레임워크를 제안한다. JARSIO는 TCP/IP 통신을 기반으로, OSGi 환경에서 동적으로 재구성되는 다양한 서비스들을 원격지에서 자유롭게 호출 및 연동 가능할 수 있도록 지원한다.
