1 PlanetLab, SDN and other testbeds in Finland Andrei Gurtov HIIT, Aalto University 15.09.2014

2 Planetlab PlanetLab in Finland HIIT site – 1 st one Oulu site Now part of planetlab.eu Test network at HIIT 1 Gbps direct Funet IPv4/6 address allocations Cisco router Server rack Secure Remote Monitoring of Personal Health Appliances (SEMOHealth)

3 SDN+SDR/WARP Testbed at Oulu World’s first Cognitive Radio Call in 2010

4 Oulu/Budapest 3.5G Validation Testbed Testing Ultra-flat Network architecture with different security options

5 Optimal Backoff Protocol for WiFi Networks WiFi testbed (12 stations) Our empirical evidence, simulation results and an analytic model reveal that two new protocols achieve nearly perfect fairness and throughput up to 100% higher than in standard backoff Decrease collision rate by more than half and to reduce delays in delay sensitive traffic.

6 Vuokatti World’s 1 st Undeground Ski Tunnel 1,210m Great for testing NLOS wireless communication Usecase: Secure networking of locomotives at opposite sides of a train with VPLS

7 Tunnel: Ski-tunnel in Vuokatti (Finland); Length: 2,0 km; Max relief 18 m; Pipe shape; Similar to: Mine tunnel; Subway. RX positions: 150, 200, 250 and 300 m. Each Point: Stand with metallic plate; Embedded PC with Wi-Fi; Antennas Laptop: Controller; Iperf (Server or Client)

8 Collaboration with ICSI/Berkeley Scott Shenker Bandwidth (and other resource) allocation in datacenters for strategic tenants The need for free Map-Reduce traces from production datacenters (Everybody is using the same years-old Facebook trace) Routing resiliency for k-connected graphs in face of link and node failure Vern Paxson Enterprise traffic analysis Traces collected at LBL Always good to have more packet traces from enterprises NetAlyzer
