EuQoS Test NetworkEuQoS Test Network 12 different testbeds
connected via GEANT based in 10 different locations in 6 countries/NRNs on 4 different access networks technologies (XDSL, LAN, WiFi, UMTS)
NRENs France : RENATER, Italy : GARR, Poland : PIONIER Portugal : RCTS Spain : RED IRIS Switzerland:SWITCH
Flexible architecture with private BGP sessions Independent of GEANT BGP routing Full meshed 131 GRE (BE) tunnels

Problems / ChallengesProblems / Challenges
Backbone network behavior not deterministic (delay, bandwidth)
IP / routing protocol modifications at edge only Efforts to establish specific test-bed
infrastructure Traffic generation tools Measurement infrastructure including time
