망 성능 테스트 (Test network performance)
두 지점 사이의 네트워크 성능 테스트는 perfSONAR의 pscheduler 명령을 통해 실행합니다.
The network performance test between the two points can be conducted using pscheduler command in perfSONAR.
perfSONAR 노드의 사용 권한이 없거나 테스트 스케줄이 밀려 있으면 명령이 실행되지 않습니다.
Test schedule would not be registered or executed if you have no permission on a perfSONAR node or a node is busy.
