Ethernet Frame size |
|
|
My professor, in a exercice sheet, asked me why a Ethernet Size is at
least 64 bytes. I've already downloaded a lot of material about this
matter, but I can't find a reasonable explanation for that. I think the
problem is the Collision Detection protocol, but I'm not sure and I
can't prove it if he asks me. Could you help me please?
Bye
Sebastiano

You're on the right path. Any text that discusses ethernet in detail will
provide the answer.
Please remember. It's your homework. You're supposed to find the answer
yourself. |

We don't do homework around here, but seeing as you've
made some effort, I'll give you some hints to explore further:
Yes, min size has to do with collision detection.
For many years, ethernet was on a long shared coax cable (now it
is more often star-wired). Two stations could start transmitting
at the same time, and it is important that all stations (especially
the two transmitters) could detect the collision.

What is the relationship between time, distance, and bits?
