Re: Ethernet collision



Bonsoir Glen,

Thanks for your reply.

When a frame is seen on the receive port during transmission,
a collision is detected and processed.

It seems difficult to use the word frame here... except if the
opposite station is in full duplex. I would say "when a signal...",
and perhaps not any signal because we have idles between frames, in
100Base-TX.

So, this formulation would seem more complex to write than those
chosen by Rich. Could you try to write how the condition of collision
is detected by the NIC, in terms of voltage, power...

Even with only a two host system, some NICs could share logic
between the receiver and transmitter, and be unable to
operate in full duplex mode.

Could you detail a little bit more? Is it at the PMD / PMA / PCS /
Reconciliation or upper part.

Best regards,
Michelot
