Given the first 20 bytes (in hexadecimal) of an Ethernet frame:
AA AA AA AA AA AA AA AB 01 23 45 67 89 AB CD EF 02 46 8A CE 01 0A 4B 8C
a) What is the Destination Address (in hexadecimal)?
c) What is the length of the data field (in decimal)?
OTA: Please give a full explanation. Thank you.
First, some intro.
Ethernet traffic is transported in units of a frame, where each frame has a definite beginning and end.
In this model we define:
Preamble Field used for synchronization, 8 Bytes - 64-bits
Destination Address Ethernet address of the destination host, 6-Bytes, 48-bits
Source Address Ethernet address of the source host, 6-Bytes, 48-bits
Type Type of data encapsulated, e.g. ...
Destination address and Data Field are highlighted.

Your manager has asked you to describe the frame format of a typical Ethernet packet. Prepare a written report. Be sure to discuss Manchester encoding, and Ethernet performance as more hosts are added to a network.View Full Posting Details
