Today is the talk with Vint Cerf from Google. Vint is considered the 'father of the Internet', he is the one that helped to create the TCP/IP protocol, which without, there would be no Internet. Vint talked with graduate students this morning of which I was gladly a part of. Vint asked each of the grad students to talk about their research, and I talked about my work, which he seemed very interested in with the social networking and community. So that was very reassuring. He asked questions to each grad student about each of his research and made suggestions, so that was really great. He's very technical and sharp, especially at his stage in his career. He also mentioned about how if he could go back to the 70s, he would want to change the design of the TCP/IP protocol and decouple the TCP layer from the IP layer, but couldn't at the time because that would increase the header size and it would be hard to sell. So, this is an example of tradeoffs for flexibility.
Vint in his talk right now, gave admiration to Prof. Kelly Gotlieb about his active research, so that was nice. I've realized this talk is being recorded by ePresence of KMDI so I'll be able to see this talk again, as I'll have to leave early to head to the CASCON conference. The title of his talk is Unravelling the Science in Computer Science. There are certain things that we can't predict and that we don't have theories for, and can't answer certain questions like how long will it take to complete a program, is this message spam, etc. He says that this is a serious challenge for the CS community.
When Vint and his colleague Bob Kahn designed the internet protocol, they separated into layers so that each layer is independent of the other, and if the layer changes, other layers will not be affected. Enterprise VPNs and firewalls were not embedded in the network design, but were added on top. Mobile devices were also not included in the IP design.
