Reimagining the Internet

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

    2. It means that internet is the network that connects with other computers operating systems devices together.
  2. What is Metcalfes law? (Hint: Use Google.)

    3. Metcalfes law states that the value of a telecommunications network is proportional to the square of the number of connected users of the system.
  3. Where geographically are the majority of Internet Users located?

    4. Asia
  4. Concerning the percentage of a countries population that uses the Internet, with what are mobiles helping?

    5. Mobile helping to allow more internet users connected to the internet.
  5. In design terms, what differentiates the Internet from earlier networks such as the Telephone and Telegraph networks?

    6. What differentiates Internet from earlier network is that presently we can connect through various reliable technologies such as fiber optic cable, wireless network, etc. compare to telephone lines.
  6. Was there a particular logic in Vint Cerf's choice of a 32 it address space for IP addresses?

    7. No.
  7. How do digital signatures relate to closing an important vulnerability in the DNS system?

    8. The digital signature can bind the domain name and the IP address.
  8. What is a sensor network? Give an example.

    9. A sensor network is a network that monitor, send data to/from multiple devices; e.g. a smart grid, it is an electricity supply network which uses digital communication technologies to detect and react to local changes in it usage.
  9. What does Vint serve describe as one of the hardest problems that he can imagine?

    10. Troubleshooting and/or detecting configuration errors.
  10. Why is cloud collaboration important?

    11. Cloud collaboration is important, because it can act as a virtual network station.
  11. How does Vint Cerf describe the job that his Internet Design did with mobile? Specifically, what was the problem?

    12. Dealing with it is awful design to him, because it could not figure out what mobile device was.
  12. How does Vint Cerf describe the job that his Internet Design did with broadcast? Specifically, what was the problem?

    13. He described the design as inefficient; and the problem was the point to point link he created.
  13. What is strong authentication? Why is the lack of this an issue?

    14. Strong authentication is a method used to verify and identify users or device strictly before authenticating communication. The problem is that too many anonymous users and devices will try to gain access prior to authentication.
  14. In an Internet context, what is the overrun problem?

    15. Overrun problem is when someone taking advantage of owner of a resources by using the resources against the ownership.
  15. What does Cerf cite as a problem with the Internet and copyright?

    16. What Cerf cite as a problem with the Internet and copyright is that material created today may not be interpreted tomorrow or copy without permission.
  16. What does Cerf mean when he talks about rotten bits? Give an example.

    17. He is emphasizing on data decay. For instance, data or material created today may not be interpreted tomorrow.
  17. Briefly describe the InterPlanetary Internet. In your description, describe how this solves the point to point InterPlanetary communications problem.

    18. The disruption tolerant protocol by Cerf made the InterPlanetary Internet to operate just as Internet Protocol to enable network to transmit on a far distance for communication efficiency compare to point to point communications.
  18. In an Internet context, what is common carriage? What implications does this have for Internet billing?

    19. Common carriage emphasized same rule for everybody. The implication is that regardless of usage percentage everyone billing is the same for whatever particular service they might have.
  19. What does Cerf means when he says that in the future, the network will disappear?

    20. He means in the future network will become available for everything anywhere in the society.

    Internet Resources

    1. What is the Internet Society?

      2. Internet Society is a non-profit organization that provide leadership in Internet related standards, policy and education.
    2. Who is Vint Cerf?

      3. Cerf is part of the internet inventors, who cooperatively designed the TCP/IP address protocol, an internet architect.
    3. Who is Bob Kahn?

      4. Kahn is the co-inventor of TCP/IP protocol together with Cerf, whose internet program DARPA was invented. He is an American electrical engineer.
    4. As articulated by Lynn St. Amour, what is ISOCs hope for the future?

      5. The ISOCs hope for the future is that reliable and open internet will be made available for everybody in the whole universe and will access the internet equally.
