2. Demo Goal How can GENI help an Experimenter Run a Complete Experiment
All the key pieces for running a complete experiment are in place.
GENI Experimenters, start using them!

3. Experiment Lifecycle and GENI

4. 1 UDT: UDP-based Data Transfer for High-Speed Wide Area Networks,
Today’s Experiment
Explore the effect of network delay in the performance of UDP (UDT1) and TCP (FTP) based file transfers.
Test your ideas in GENI!
1 UDT: UDP-based Data Transfer for High-Speed Wide Area Networks,
Yunhong Gu and Robert L. Grossman, Computer Networks (Elsevier). Volume 51, Issue 7. May 2007.

5. Execute experiment Let’s do this live!
Starting from the middle since this step will take time!
Used Omni scripting to orchestrate the experiment
Other tools : Gush, OMF/OML
Let’s do this live!

6. Design experiment Simple experiment: a server a client
Resources at ProtoGENI Utah
GEMINI monitoring software
Simple experiment:
a server
a client
a link with tunable parameters
monitor performance
<Rspec>
client
server

7. Deploy experiment Let’s do this live!
So jeanne is going to load the rspec for this experiment. In this case my job was easy because UDT is part of the example experiments that are on the wiki that Mark mentioned before. I just needed to download that rspec.
Let’s do this live!

8. Monitor experiment Let’s do this live!
We just need to run one command on a terminal and it will go off work for 20 minutes and instrumentize your slice. Once it is done It will print all the info you need to login to the web-portal for monitoring your slice.
Let’s do this live!

9. DONE Execute experiment Let’s do this live!
Starting from the middle since this step will take time!
Used Omni scripting to orchestrate the experiment

DONE
Let’s do this live!

10. Analyze experiment
Let’s watch this live!

11. Archive experiment

14. Run GENI, Run! Bottom line, you can do this yourself!
To run this Experiment :
2 accounts (GENI, irods)
4 tools (Flack, GEMINI, Omni, iRODS)
To configure them
2 files, 3 commands
Bottom line, you can do this yourself!
Come to the Experimenter Drop-in session and try it out
