2. Are End-to-End Dynamic Circuits really practical?

3. I need my TeraBytes here
Dynamic circuits?
I need my TeraBytes here

4. I need my TeraBytes here
Dynamic circuits?
Here is your pipe!
Here is your pipe!
I need my TeraBytes here

5. I need my TeraBytes here
Dynamic circuits?
Here is your pipe!
Here is your pipe!
I need my TeraBytes here
but...

6. Dynamic circuits? but... .... Here is your pipe! Here is your pipe!
I need my TeraBytes here
but...
Have you set up the routing?
Have you opened the firewall?
Give me one week
to call the
maintenance window!
How many circuits
did you say?!?
....
How do I debug it?

7. What's going on out there?

8. Social networking

9. Can't we do the same? Are you connected to CERN? Yes! Let's peer there
Are you also at Starlight?
Yes! Let's get
redundancy there

10. Bandwidth on Demand? Yes please!

11. Bandwidth on Demand How fast? Choose your size!
I need my TeraBytes here. Now!

12. No problem: business as usual! No problem: business as usual!

13. In practice:

14. Proof of Concept: the LHCOPN
- Traffic between any pairs of connected sites
- Effective use of expensive circuits
- Dynamic bandwidth allocation on transatlantic circuits

15. What's next? Distributed IXP* for the LHC
