2. Overview Desired properties for tools and testbeds
Small inventory of tools and testbeds
Sharing of resources

3. Desired properties – technical
ease of use, low overhead
example planetlab interface (Timur’s MOOC)
dealing with user creation?
reproducibility
sustainability of the testbed (what happens when the funding goes out?
offline tools for availability (on trains, ...)

4. Desired properties – community related
How to build a community
How to deal with success
Sustainability of the testbed (what happens when the funding goes out?
Need for low cost maintainance
Incentives for institutions to upgrade hardware
Making it available for industry (can be a source of revenue)

5. Repository of tools Capture and analysis Network emulation
Experiments on the Internet
TCP behavior
(Interconnected) testbeds

6. Capture and analysis Wireshark (https://www.wireshark.org/):
for illustrating part of protocols (need correlations on both ends)
headers and encapsulation (intro to networking)
Understand packet flow
congestion control (illustrate congestion avoidance)
find attacks
ipsec and key negotiation
opentraces

7. Capture and analysis bro: for flow based tranalyzer
big data traces analysis
can be used as IDS
packet or flow-based
http sniffer plugin

8. Network emulation gns3 junosphere, olive mininet emulate routers
Same as above
mininet
to do firewalling
find out vulnerabilities of systems
SDN
use vagrant to do the setup (Nick Feamster)

9. Experiments on the Internet
planetlab
exposing experimenters to the “real” Internet
routing changes
geographically dispersed measurement points (eg: anycast)
internet measurements: ping, traceroute, iperf. Traceroute from A to B and vice versa. Find symmetric routes, asymmetric routes, … (Timur and Renata) 2 INRIA researchers provided the interface. Iperf to measure available bandwidth, validity of the measurements. Soon available outside the MOOC.
for intro to networking: analysis of an http trace (TCP behavior)
supports IPv6

10. Timor’s MOOC interface to planetlab: dashboard

11. Launch

12. Results

13. Experiments on the Internet
GENI
reservation of resources. Compute and memory. Do SDN like experiments.
VINI (GENI with ability to control the topology)
GTS: Geant testbed service (Jerry Sobieski)
9 PoPs across Europe where you can get virtualized resources. reserved 10 Gbps links.
RIPE atlas:
traceroutes, ping: similar uses to planetlab as used in Timur and Renata’s MOOC.
SamKnows, Bismarck, archipelago, …

14. TCP behavior linux modprobe NS3: network simulation.
to load different TCP versions and study congestion (look at logs). We have surprises because the implementation in linux differs from what we teach.
→ ns3 has modules to do that.
NS3: network simulation.

15. (Interconnected) testbeds - wireless
NITOS
Wireless lab in greece
FIT IOT Labs
study the range of different wireless technologies
study the energy consumption
configure sensors, retrieve values from them
Illustrate RPL

16. Interconnected testbeds - Wired
Virtual Wall (IMEC)
Rack with loads of servers. Create a virtual network. Network emulation at large-scale.
Grid 5000 is similar to virtual wall, starbed.
ToMaTo: gui (same author as g-lab)
Tomato-lab.org or
Setting up of virtual topologies
JFED: also from IMEC. java federation
Servers, links, install on testbed of your choice (FIRE -> federation with common API) Virtual wall is compatible, planetlab and GENI as well.

17. Need for visualization
timeline diagram (chronograph), illustrations for DoS
BGPplay
Traceroute visualization (Roma Tre -> RIPE)
omnigraffle to do the animations, keynote, ppt, …
gnuplot , R, S, …

18. How to share materials What How Pcap files
Labs and instructions for different environments
Courses
VMs
How
Wiki, github, youtube
Different MOOC platforms
FUN (France Université Numérique)
learnIntSec.org
