Reimagining the Internet

1. Vint Cerf has described the InterNet as a homogenous network that connects heterogeneous computers. What did he mean by that?

The network connects computers and other devices with different operating systems.

2. What is Metcalfe's law? (Hint: Use Google.)

It states that the value of a telecommunication network is proportional to the square of the number of connected users.

3. Where geographically are the majority of Internet Users located?

Asia.

4. Concerning the percentage of a country’s population that uses the Internet, with what are mobiles helping?

They allow more users to connect to the internet.

5. In design terms, what differentiates the Internet from earlier networks such as the Telephone and Telegraph networks?

In earlier networks they had to lay down long lines to connect users while now we can use microwave, satellites and many other new technologies to connect.

6. Was there a particular logic in Vint Cerf's choice of a 32 it address space for IP addresses?

No.

7. How do digital signatures relate to closing an important vulnerability in the DNS system?

They can bind the domain name and IP address.

8. What is a sensor network? Give an example.

It’s a network that collects and sends information from various devices. An example is standalone devices in homes like refrigerator and thermostats that can connect to the internet.

9. What does Vint serve describe as one of the hardest problems that he can imagine?

Troubleshooting configuration.

10. Why is cloud collaboration important?

Currently, there is not a standard model for clouds to communicate with each other. Thus clouds are interconnected.

11. How does Vint Cerf describe the job that his Internet Design did with mobile? Specifically, what was the problem?

He describes the design as a rotten job for dealing with mobility. He did not realize at the time that nodes would have to change depending on the location of the device.

12. How does Vint Cerf describe the job that his Internet Design did with broadcast? Specifically, what was the problem?

He described it as imperfection for dealing with broadcast media. The problem was that he turned the broadcast media into a point to point link.

13. What is strong authentication? Why is the lack of this an issue?

A strong authentication is good quality identity. The lack is an issue because if there is no authentication then people will not use the cloud.

14. In an Internet context, what is the overrun problem?

An overrun problem is defined as someone taking advantage of your assets to defeat you.

15. What does Cerf cite as a problem with the Internet and copyright?

The problem is that what is created today might not be interpreted in the future.

16. What does Cerf mean when he talks about rotten bits? Give an example.

He is talking about data decay. the example is what is created today might not be interpreted in the future.

17. Briefly describe the InterPlanetary Internet. In your description, describe how this solves the point to point InterPlanetary communications problem.

In simple words it is like internet in space, the purpose of this would be so that people that work like at NASA could have a richer network to work

18. In an Internet context, what is common carriage? What implications does this have for Internet billing?

Same rules to everybody and all customers are served under the same terms and condition.

19. What does Cerf means when he says that in the future, the network will disappear?

He is trying to say that in the future everything will be network capable.

Internet Resources

1. What is the Internet Society?

An international, non-profit organization founded in 1992 to provide leadership in Internet related standards, education, and policy.

2. Who is Vint Cerf?

One of the fathers of the internet. He co-designed TCP/IP protocols and the basic architecture of the internet.

3. Who is Bob Kahn?

Also known as one of the fathers of the internet. He invented TCP/IP, with Vint Cerf. He was also responsible for originating DARPA’s Internet program.

4. As articulated by Lynn St. Amour, what is ISOC’s hope for the future?

That everyone in the world will have equal access to a ubiquitous, reliable and open Internet and all countries of the world will be on par with each other.
