  4. EuQoS 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 16 September, 2014

  5. Problems / 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 synchronization 16 September, 2014
