Multi-Domain Network Performance Monitoring in GEANT2 A Quest for Automation and Transparency Bringing Performance Data to the End User

摘要

In the last couple of years the perfSONAR project has evolved into a robust scalable framework that offers a wide range of services for collecting network performance data which are being deployed all over the world. Data can easily be retrieved and examined using already available tools like perfsonarUI, CNM or VisualPerfSONAR. However, at this stage of development perfSONAR still has to deal with some unresolved issues. As middleware software perfSONAR is too visible to the end user and the relations between distributed services need to be officially defined. This paper proposes possible solutions to resolve these issues.
