Andrew S. Tanenbaum Edition 5th Exercise 5 Question 31 (Page No. 492)
A router has just received the following new IP addresses: 57.6.96.0/21, 57.6.104.0/21, 57.6.112.0/21, and 57.6.120.0/21. If all of them use the same outgoing line, can they be aggregated? If so, to what? If not, why not?

Andrew S. Tanenbaum Edition 5th Exercise 5 Question 30 (Page No. 492)
A large number of consecutive IP addresses are available starting at 198.16.0.0. Suppose that four organizations, A, B, C, and D, request 4000, 2000, 4000, and 8000 addresses, respectively, and in that order. For each of ... the first IP address assigned, the last IP address assigned, and the mask in the w.x.y.z/s notation.

Datagram networks route each packet as a separate unit, independent of all others. Virtual-circuit networks do not have to do this, since each data packet follows a predetermined route. Does this observation mean ... the capability to route isolated packets from an arbitrary source to an arbitrary destination? Explain your answer.

Let $N$ be the number of nodes and $M$ be the number of edges. For Link state routing how many message exchanges (roughly, explained as a function of the above parameters) need to be exchanged to build the topology at each and every node in the network? $\text{Min } (N+M, N*M)$ $\text{Max } (N+M, N*M)$ $N*M$ $N+M$

Kurose and Ross Chapter 4th Network Layer Problem 16
Q: Suppose an application generates chunks of 40 bytes of data every 20 msec, and each chunk gets encapsulated in a TCP segment and then an IP datagram. What percentage of each datagram will be overhead, and what percentage will be application data? Please someone who knows explain also. Thanks in adv. - Madhav.
