초록

그리드는 지리적으로 분산된 다양한 컴퓨팅 자원을 초고속 네트워크로 연결하여 고속 연산과 대용량 데이터의 처리를 가능하게 하는 기술이다. 서비스 품질이 보장되는 그리드 환경의 작업 수행을 위해서 컴퓨팅 자원뿐만 아니라 네트워크 자원의 관리와 제어가 요구된다. 본 논문에서는 그리드 네트워크 경로 및 자원의 생성과 예약을 지원하기 위하여 그리드 네트워크 자원의 정보 모델과 그리드 네트워크 서비스 인터페이스를 정의하였다. 그리드 네트워크 서비스 인터페이스에는 기존 GLIF의 자원 생성 및 예약 관련 메시지 이외에 그리드 네트워크 경로와 통보 메시지를 추가로 정의하였다. 또한, 두 단계 자원 예약 메커니즘을 지원하기 위하여 관련 상태와 메시지를 정의하였다. 그리드 네트워크 자원의 정보 모델과 그리드 네트워크 서비스 인터페이스를 이용하여 네트워크 자원 관리 시스템을 설계 및 구현하였으며, GMPLS 기반의 제어및 전달망을 갖는 그리드 환경에서 자원의 예약과 할당 및 해제를 실험하였다.

Grid technology enables high performance computation and mass data processing by connecting geographically distributed computing resources to high-speed network. To carry on grid tasks requiring guaranteed quality of service, we need to build converged infrastructure which controls and manages network resources as well as computing resources. In this paper, we defined grid network service interface and information model to support grid network path, resource creation and reservation. In addition to resource creation and reservation messages of the existing GLIF, grid network path and notification messages were defined in the grid network service interface. We also defined related statuses and messages for two-phase resource reservation mechanism. We designed and implemented network resource management system based on the grid network information model and service interface. We experimented in resource reservation, allocation and release of network resources in grid environment with GMPLS control and transport network.
