Abstract

The most representative research network in Korea, KREONET has developed the NSI based NSA (Network Service Agent) technology. The developed NSA supports web service and provides services for reservation, provision, release and termination of network resource, whenever users want to utilize them. In this paper, the system blocks of the developed NSA and flows of NSI interface massage are presented firstly, Also, service test results for NSI connection reservation is given through internet communication of the web portal system to operate as the RA NSA and the NSA, Finally, it is confirmed that reservation, provision, release and termination of network resource can be established through NSI messages based on reservation information from user, between the web portal and the NSA.

한국을 대표하는 연구망인 KREONET은 OGF에서 제안한 NSI (Network Service Interface) 기반의 네트워크 자원서비스에이전트 (NSA) 기술을 개발하였다. 개발된 NSA은 웹 서비스를 지원하며 MPLS 제어평면 기술을 이용하여 사용자가 원하는 시간 때에 네트워크 자원 (대역폭, 경로)을 예약, 구성, 해제, 종결 해 줄 수 있다. 본 논문에서는 개발되어진 NSA의 시스템 블록 및 NSI 인터페이스 메시지 흐름에 대하여 알아본다. 또한 NSI 요청 메시지를 위한 클라이언트, 확인 메시지를 위한 서버로 동작하는 Reguester NSA를 웹포털시스템으로 구현하여 개발된 NSA과의 통신을 통해 NSI 연결 예약 서비스를 시험하였다. 사용자로부터 제공 되어진 예약정보를 받아 웹 포털 시스템과 NSA과의 NSI 인터페이스 메시지를 통해 네트워크 자원을 예약, 구성, 해제, 종결 할 수 있었다.
