IPsec security

Discuss some of the problems NATs create for IPsec security. (See [Phifer 2000]). Can we solve these problems by using IPv6? Why deployment of IPv6 has been slow to date. What is needed to accelerate its deployment?

Multicast applications

Name several multicast applications. Which of these applications are well-suited for the minimalist Internet multicast service model? Why? Which applications are not particularly well-suited for this service model?

Advantages and Disadvantages of Subnets

What are some disadvantages of subnets?

TCP Connections

Supposed two TCP connections are present over some bottleneck link of rate R bps. Both connections have a huge file to send (in the same direction over the bottleneck link). The transmissions of the files start at the same time. What is the transmission rate that TCP would like to give to each of the connections?

IPv4 versus IPv6

I personally think the deployment of IPv6 has been slow because the Internet is still using IPv4. Until the whole scope of Internet users are forced to change to IPv6 there will be no acceleration of its deployment. The old saying comes into the forum; why stop using something that you know works and you are happy with?
