Within the scope of the European research and education network project GEANT2, including a framework for performance measurements, the need for statistical analysis and interpretation of network performance metrics has to be satisfied. Following the IETF approach, a measurement system for metrics as one-way-delay (OWD), OWD-variation (OWDV) and packet loss(More)
This investigation provides performance measurements over layer 2 and layer 3 connections across the European testbed MUPBED, the German testbed VIOLA and the German Research Network X-WiN. The analysis first evaluates Quality of Service (QoS) parameters delay and jitter of layer 2 tunnels across both testbeds and includes an assessment of the jitter(More)
Zusammenfassung: Zur QoSund SLA-Überwachung sowie zur Vereinfachung der domänenübergreifenden Fehlersuche der Dienste im europäischen Netzverbund GN2 wurde eine föderierte Multi-Domain Monitoring Architektur namens perfSONAR entwickelt. perfSONAR definiert geeignete Metriken und Messverfahren zum Performance Monitoring. Es realisiert eine Architektur, um(More)
