초록

본 논문에서는 광인터넷의 구조 설계에 대한 분석과 광서비스망에서 UNI(User Network Interface) 시그널링 프로토콜을 이용한 광전송 실험을 시행하였다. 광인터넷의 계층에 따른백본망, 서비스망, 액세스망에 대한 세부적인 구조를 보여주었고, 각 계층에서 필요한 기능들에 대하여 기술하였다. 이어서 광전달 계층의 제어 구조, 운용관리망 구조, 망간 연동 기술 그리고 라우팅 및 신호망에 대한 기능적 요구조건들을 제시하였다. 이러한 광인터넷망에서 OIF(Optical Internetworking Forum)에 의해서 규정된 UNI 시그널링 프로토콜을 사용하여 전송 실험을 하였다. LSP(Label Switched Path)에 트래픽을 전송하여 설정된 경로를 따라서 메시지가 UNI에 전달되었고, 스위칭을 통하여 최종 목적지에 도착한 TCP(Transmission Control Protocol) 패킷(packet) 값을 보여줌으로서 실시한 광전송이 성공적으로 완료되었음을 확인하였다.

In this paper, the structural design of optical Internet is analyzed and by using UNI (User Network Interface) signaling protocol an optical transmission experiment was performed. The hierarchical structure of the basic optical Internet consists of the backbone network, the service network and the access network. The necessary functions for each layer were described as follows: Control structure of the optical transport layer, network operation and management structure, internetworking technology of sub networks, routing and signaling technology. By using UNI signaling protocol from OIF (Optical Internetworking Forum), the optical transmission in the proposed structure of the optical Internet network was experimented. By the traffic generation of LSP (Label Switched Path) data packets along the route-configuration was delivered to UNI. Finally, by showing the value of TCP (Transmission Control Protocol) packets the optical transmission was completely and successfully demonstrated.
