Chapter 6, Problem P22P
Explanation of Solution
Given:
The leftmost router in the “Figure 6.33” is replaced by a switch. The hosts and the rightmost router are star-connected to the switch.
To find:
- MAC address (source and destination), source address and destination address from the host A to the switch.
- MAC address (source and destination), source address and destination address from the switch 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.
MAC address, source address and destination address from the host A to the switch.
| Headings | Address |
| MAC address |
Source address: 00-00-00-00-00-00 Destination address: 55-55-55-55-55-55 |

Host A and B are communicating over a TCP connection, and Host B has
already received all bytes up through byte 100 (including Byte 100) from A. Suppose
Host A then sends two packets to Host B back-to-back. The first and second packets
contain 40 and 80 bytes of data, respectively. Host B sends an acknowledgment
whenever it receives a packet from Host A.
a. What is the sequence number of the first packet sent from Host A to Host B? What is
the sequence number of the second packet sent from Host A to Host B?
b. If the second packet arrives before the first packet, in the acknowledgment of the
first arriving packet, what is the acknowledgment number? .

The first and second segments contain 80 and 40 bytes of data, respectively. In the first segment, the sequence number is 127, the source port number is 302, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A.
d. Suppose the two segments sent by A arrive in order at B. The first acknowledgment is lost and the second acknowledgment arrives after the first timeout interval. Draw a timing diagram, showing these segments and all other segments and acknowledgments sent. (Assume there is no additional packet loss.) For each segment in your figure, provide the sequence number and the number of bytes of data; for each acknowledgment that you add, provide the acknowledgment number.
