2. Prologue Internet has become a victim of its own success… A research prototype and a file transfer mechanism for physicists became a social necessity and it has evolved so much that it has become difficult to make changes. Changes are needed. It is not fair on our part to blame a network that was designed 30 years ago. Learning from experience is good and Internet is a fantastic experience to learn from. It shows the perfect evolution. People got frustrated and began to question the very perfection of the Internet!

3. Overcoming the Internet Impasse Through Virtualization Authors: Larry Peterson, Scott Shenker, Jonathan Turner Presentation By: Rahul Potharaju, Mark Ison Advisor: Aleksander Kuzmanovic

4. I got a new idea today morning – How about changing the world? Our goal in writing this paper is to issue a call to action… • Are we trying to start world peace or redesign the internet?

5. I got a new idea today morning – How about changing the world? Here we call on the community with paper designs that have no future, and instead return to its roots of applied architectural research with the intention of once again changing the world. Take a moment to appreciate the hypocrisy of this statement. They are promoting more widespread use of their own design

6. Establishing Credibility (OR NOT) • Did they just Google new internet architectures and cite them all? • What is the rationale for this order of citations? • While there is increasing interest in new architectures to address these challenges (e.g., see [24, 22, 3, 9, 27, 23, 7, 4, 6, 5, 28, 8])‏

7. Call for Chaos … and to urge everyone to cease being satisfied with paper designs that have no future. • Propose a “Good Luck Charm” (in the form of multiplexed overlay networks) which has the following properties: • New Protocols • New Services • Bring thy wrath upon earth! Behold XIP – An alternative to IP Pun Intended 

8. Barnacles revisited… Overlays become a barnacle (hurdle). What is needed is not so much a technical change in how overlays are built, but rather a philosophical change in how they are used. Virtual testbeds are therefore less of a technical advancement • Question the very perfection of the Internet, accusing it of being defaced by barnacles. Isn’t this evolution in the first place? • Why aren’t we building a 20 GHz computer instead of incrementally going up the ladder? • Again, are we being more philosophical?

9. Do I still need you? Internet Engineering Task Force, a collection of task forces at work on developing standards for Internet protocols and architectures. Proposes a scheme in which thousands of researchers and students can develop and deploy a myriad of protocols, algorithms and services. Do we still need IETF?

10. Deployment… Too Abstract A New Generation service provide (NGSP) chooses a particular new architecture and then constructs an overlay supporting that architecture. The NGSP also distributes proxy software that allows anyone, anywhere, to access their overlay… Seize overlays as an opportunity to radically change the architecture, not merely provide limited enhancements - This could be established by a single daring NGSP • There isn’t a “What-if?” analysis. Who would be willing to become the scapegoat?

11. Is Virtual really Virtual? Ref: Overlay-Friendly Native Networks: A Contradiction in Terms? We would like to add that the contradiction arises because the overlay service is unable to provide the best performance autonomously. Motivate the need for support from native layers

12. So where’s the contradiction you may ask… Ref: Overlay-Friendly Native Networks: A Contradiction in Terms? We would like to add that the contradiction arises because the overlay service is unable to provide the best performance autonomously. All these are prohibitively complex

13. Are we there yet? Ref: The End of Internet Architecture Are we at a point in the development of distributed communications systems where the concept be replaced by a different way of dividing up the design space? … … … whether the very idea of a network architecture at this point in history is a help or hindrance… The argument is that recent Internet Architecture research is not without merit, but it is currently misdirected towards creation of one or more new “network” architectures which retain the outdated distinction between routers and end-systems.

14. Hmm… Trying to fit somewhere?

15. So what is OTIITV then? Isn’t the spread of technical innovation a little too narrow?

16. From a creator’s POV:

17. A baby's first few years are marked by many milestones. Just because he isn’t toddling properly now, doesn’t mean that he will never learn to “walk” The very fact that he is attempting to walk is an evolution by itself. Internet is an evolving mechanism too – Our responsibility lies in aiding its evolution not to question its very existence!
