Explanation of Solution
Figure 6.33:
The “Figure 6.33” contains:
- Two routers.
- Three switches (LAN).
- Three subnets.
- Each subnet contains two host computers.
- Subnet 1 contains two hosts named “A” and “B”. Both the two hosts are connected through a same switch.
- Subnet 2 contains two hosts named “C” and “D”. Both the two hosts are connected through a same switch.
- Subnet 3 contains two hosts named “E” and “F”. Both the two hosts are connected through a same switch.
Assigning IP and MAC addresses:
Given:
Consider that Host A sends a datagram to the Host F.
To find:
- MAC address (source and destination), source address and destination address from the host A to the left router.
- MAC address (source and destination), source address and destination address from the left router to the right router.
- MAC address (source and destination), source address and destination address from the right router to F.
Solution:
The source and destination address will not change as it is constant.
From the above figure; MAC address, source address and destination address from the host A to the switch...

Host A and B are communicating over a TCP connection. Host B has already received from Host A all bytes up through byte 23. Suppose Host A then sends two segments to Host B back-to-back. The first and the second segments contain 30 and 50 bytes of data, respectively. In the first segment, the sequence number is 24, the source port number is 3000, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A.

mentation (i.e., at link layer) in terms of purpose?
2. Suppose that host A is connected to a router R1, R1 is connected to another router, R2, and
R2 is connected to host B. Suppose that a TCP message that contains 800 bytes of data and
20 bytes of TCP header is passed to the IP function at host A for delivery to B. Show the
Total length, DF, MF, and Fragment offset fields of the IP header in each packet transmitted

bytes including a 14-byte frame header, link R1-R2 can support a maximum frame size of 512
bytes, including an 8-byte frame header, and link R2-B can support a maximum frame size
of 432 bytes including a 12-byte frame header.)
