초록

의학 분야에서 가파르게 증가하는 인터넷 사용과 다양한 서비스 요구사항을 만족시키기 위한 연구가 활발하게 진행되고 있다. 특히 하나의 광섬유를 통해서 수 테라비트를 운반할 수 있는 광 인터넷은 생존 필요성의 다양한 형태를 만족시키기 위해서는 지능적인 것을 필요로 한다. 본 논문에서는 IP over WDM 네트워크에서 다양한 복구 요구사항을 만족하는 새로운 복구 기법을 제안한다. 이 기법은 복구 서비스를 세 개의 클래스로 구분하고 각 클래스를 위해 서로 다른 우선순위를 가진 공유 복구와 전용의 보고 기법을 활용한다. 또한 이 방법을 지원하는 정보 데이터베이스를 위한 구성 기법이 제안된다. 이 기법은 복구 시간, 블로킹 비율 그리고 자원 활용 측면에서 각 클래스별로 서로 다른 정도의 복구 요구사항을 제공한다. 이 기법을 이용하며, 손실 없이 의학 데이터를 전송할 수 있다.

Various researches are actively studied to satisfy exponentially increasing the usage of the Internet as well as the diverse service demands. Especially the Optical Internet that delivers several Tbps through a single optical fiber requires the intelligence to satisfy the various types of survivability requirements. In the paper, a novel recovery scheme that satisfies the various restoration demands in IP over WDM networks is proposed. The scheme classifies the restoration services into three classes and applies dedicated protection and shared restoration scheme with different priorities for each class. Also, a configuration scheme for information database to support the scheme is proposed. This scheme satisfies the different degree of restoration demands in terms of restoration time, blocking rate and resource usage. With the scheme, medical data can be transmitted without loss.
