2. The Incident

3. The Incident

6. IP Transit vs Peering traffic volumes

7. UNINETT Links

8. AMSIX

9. LINX

10. Netnod

11. So what can we do?
Connect Akamai and other CDN’s directly to the Network Core
Ensure that no single customer (NREN) connection can overflow the backbone
But, If there is a big live event that has a huge interest, all you can do is,, Pray
or impose rate limit policies, block networks etc.. which you really don’t want to do.. but are forced to..

12. Because they are during the summer holidays so no one is at campus…
2012 major sports events
European Soccer, Olympics
Should we worry? NO
Why?
Because they are during the summer holidays so no one is at campus…

13. Impact of cloud services
Current traffic flows are mainly within the campus (East-West)
Servers and services like mail, backup etc. etc. is on campus
Future traffic flows will be from Universities towards the cloud’s as in IaaS, PaaS,,, anythingaaS (North-South)
Not to mention desktop and mobile device synchronization services and collaboration (dropbox, box etc.)

14. Content, cloud and social media

15. ? The good news Major live events can be predicted
The impact of cloud, content and social media services can be foreseen
.. But it is happening fast so be prepared and it is not the fault of the CDN’s so don’t shoot the messenger.. ?
