Abstract

Devices of home network system have different control data formats according to each product company. Therefore, types or protocols of digital devices are various. Also, interaction operating environments are different among various devices. These characteristics of home network system don't support sufficiently functionalities such as data comparability, concurrent control, dynamic plug-in, and so on. That is, the degree of reusability of home network system is very poor. This paper proposes a framework which can be coverable to the scope of reusability widely and a design technique based on framework in order to improve reusability. That is, we extract various parts of home network systems as variation points, classify and define these as variation types, propose a framework which can be reusable those, and proposes a design technique of variability to improve reusability. Finally, proposed technique can be reusable to various domains by applying proposed reusability framework into real home network system's design.

홈 네트워크 시스템에서는 가전 기기들이 각기 제조된 회사에 따라 서로 다른 제어 데이타 포맷을 가지고 있으며, 디지털 기기(디바이스)의 유형과 프로토콜이 다양하다. 또한 다양한 디바이스들 간의 상호 운영 환경이 상이하다. 홈 네트워크 시스템이 이와 같은 특성들로 인해 데이타 호환성나 동시 제어, 동적 플러그-인과 같은 기능들이 미약하게 지원되고 있다. 이로 인해 홈 네트워크 시스템의 재사용성은 매우 빈약한 상태이다. 본 논문에서는 홈 네트워크 시스템의 재사용성을 향상시키기 위해 가변성의 범위를 폭넓게 다룰 수 있는 재사용 프레임워크와 이를 기반으로 한 가변성 설계 기법을 제시한다. 즉, 홈 네트워크 시스템의 다양한 부분들을 가변부로 추출하여 이를 가변성 유형으로 분류 정의하고 이를 재사용 할 수 있는 프레임워크를 제안하며, 이러한 프레임워크를 기반으로 재사용성을 향상시키기 하기 위한 가변성 설계 기법을 제안한다. 재사용 프레임워크를 실제 홈네트워크 시스템 설계에 적용함으로써 다양한 도메인에 재사용될 수 있음을 증명한다.
