Ethernet Frame Analysis, Assignments of Computer Networks

University of South Carolina (USC) - ColumbiaComputer Networks

A detailed analysis of an ethernet frame, including the identification of the 48-bit ethernet address, the destination address, the frame type field, the location of specific characters within the frame, the source address, and the hexadecimal values for the source and destination addresses in the ethernet frame containing the arp request and reply messages. Various aspects of ethernet frame structure and the corresponding upper layer protocols, such as ip and arp, making it a valuable resource for understanding network communication and troubleshooting network-related issues.

CSCE 416 Homework 4
1. What is the 48-bit Ethernet address of your computer?
a. 4c:79:6e:3d:9e:97
2. What is the 48-bit destination address in the Ethernet frame? Is this the Ethernet
address of gaia.cs.umass.edu? (Hint: the answer is no). What device has this as its
Ethernet address? [Note: this is an important question, and one that students sometimes
get wrong. (Re-)read Section 6.4 in the text and make sure you understand the answer
here.]
a. 00:00:00:00:01:01
b. No they are different
c. The Ethernet address of my local router
3. Give the hexadecimal value for the two-byte Frame type field. What upper layer protocol
does this correspond to?
a. 0x0800
b. "0x0800" corresponds to the upper layer protocol, which is IP (Internet Protocol).
4. How many bytes from the very start of the Ethernet frame does the ASCII “G” in “GET”
appear in the Ethernet frame?
a. There are exactly 54 bytes prior to the ASCII “G” for the GET request.
5. What is the value of the Ethernet source address? Is this the address of your computer,
or of gaia.cs.umass.edu (Hint: the answer is no). What device has this as its Ethernet
address?
a. 00:00:00:00:01:01
b. The Ethernet source address, which is not my computer's or
gaia.cs.umass.edu's. It typically belongs to a router.
6. What is the destination address in the Ethernet frame? Is this the Ethernet address of
your computer?
a. 4c:79:6e:3d:9e:97
b. Yes it is the same.
7. Give the hexadecimal value for the two-byte Frame type field. What upper layer protocol
does this correspond to? (Ethernet II-> Type)
a. 0x0800
b. "0x0800" corresponds to the upper layer protocol, which is IP (Internet Protocol).
8. How many bytes from the very start of the Ethernet frame does the ASCII “O” in “OK”
(i.e., the HTTP response code) appear in the Ethernet frame?
a. There are 67 bytes before the “O”.

CSCE 416 Homework 4

  1. What are the hexadecimal values for the source and destination addresses inthe Ethernet frame containing the ARP request message? a. ff:ff:ff:ff:ff:ff b. 4c:79:6e:3d:9e:
  2. Give the hexadecimal value for the two-byte Ethernet Frame type field. What upper layer protocol does this correspond to? a. 0x b. The corresponding upper layer protocol is ARP.
  3. Where in the ARP request does the “question” appear – the Ethernet address of the machine whose corresponding IP address is being queried? a. The Target MAC address is 00:00:00:00:00:00. b. This broadcast will query the machine which IP address is 10.35.192.1.
  4. Now find the ARP reply that was sent in response to the ARP request. Where in the ARP message does the “answer” to the earlier ARP request appear – the IP address of the machine having the Ethernet address whose corresponding IP address is being queried? a. Sender IP address: 10.35.192. b. Sender MAC address: 00:00:00_00:01:01 does the “answer” to the earlier ARP request.
  5. What are the hexadecimal values for the source and destination addresses inthe Ethernet frame containing the ARP reply message? a. 4c:79:6e:3d:9e: b. 00:00:00:00:01:
