This presents the Grid Manager and Network Instrumentation service on top of KITE, which allow to test any communication system with total programmatically control over the network. Test the behaviour of your (or your competitor's) communication system or more specifically the bandwidth estimation, congestion control, adaptation, .......

2. Content
• Objective
• Setup
• KITE-Janus-Test
• Network Instrumentation with the
Grid Manager

3. Objective of tutorial
The objective of this Tutorial is run the Janus Video Call test on the
Grid Manager with Network Instrumentation.

4. Objective: reproduce simple load testing

5. Objective: reproduce simple load testing

6. Objective: reproduce Jitsi experiment, automatically

7. Objective: test network resilience, adaptation (BWE, CC)

8. Setup
• Setup KITE by following instructions from:
• https://github.com/webrtc/KITE
• Setup KITE-Sample-Tests by following instructions from:
• https://github.com/CoSMoSoftware/KITE-Sample-Tests/tree/master/
KITE-Janus-Test

9. KITE-Janus-Test
• The KITE-Janus-Test includes tests for 4 demos:
• Echo Test: https://janus.conf.meetecho.com/echotest.html
• Streaming: https://janus.conf.meetecho.com/streamingtest.html
• Video Call: https://janus.conf.meetecho.com/videocalltest.html
• Video Room: https://janus.conf.meetecho.com/videoroomtest.html
• Today we’ll be using the Video Call test
• To run the test:
• r configsvideocall.januscon.config.json

12. Network Instrumentation

13. Network Instrumentation
• GOOD for 30s
• Up/Down BW limit at 800 kbps for
60s on GW1 (Alice’s IP Router)
• GOOD for 30s
• You can check the pre-configured scenario for this test in Test Runner -
> Tests

14. Network Instrumentation
• The Grid Manager creates a Test
Bed on AWS with multiple Gateways.
• Gateway are Linux VMs with multiple
NITs and configured as routers
• The main advantage of using
Gateways is that the Clients are OS
agnostics. We can simulate exactly
the same network conditions with
Clients on Windows, Linux and
Android (and Mac/iOS on our
Physical Grid)
• For Firefox and Chrome testing,
where Linux is fine, KITE is also able
to simulate NW conditions directly on
the Clients (Gateways are not
required)

15. Network Instrumentation
• Virtually any Network Profile
can be configured to
simulate:
• Bandwidth limit
• Packet Loss
• Latency
• Jitter
• Packets reordering,
corruption, dropping,
duplication
• Firewalls & NAT
• Anything else that can be
run on a Linux VM/router…

16. Running the Test

17. Upload the Test Script
1. Go to Test Runner -> Upload Scripts
2. Choose File -> Browse to KITE-Sample-Tests > KITE-Janus-Test >
target

18. Run the Test
1. Go to KITE Requests
2. Select KITE_000000001 or KITE_000000002 (they are the same)

19. Select the Grid
Both Grid are the same. Select one that is available.

20. Configure the Clients
• Enter [[0,1]] in Custom Matrix (to run only the combination 1st Client vs
2nd Client)
• Name: Alice & Bob
• Video
• Christa for Alice
• Berkely for Bob
• Launch

21. Monitor progress via the Logs

22. Monitor progress via the Logs
• Wait until it reaches: Execute(DEFAULT) completed

23. Check the Test Reports
• Scroll down and click on the Steps for Alice and Bob called ‘Generate
Charts’ to see the getStats charts

24. Next opportunity to hear about KITE
IIT-RTC in Chicago,
October 14th to 16th.
