Fun puzzle: can you make a pure analog (bonus: unpowered) ethernet throttling knob?
-
-
I don't think this is possible for 1000Base-T. That has a somewhat complicated physical layer that involves both directions transmitting on the same wires simultaneously (and hence why passive taps do not work).
-
Thus why you start by eliminating it, forcing 10/100.
-
The problem then is how to throttle from 10/100 Mbit down to kbit rates. Basic idea: simulate collisions.
-
Collision detection is off if full duplex is negotiated
-
Then force half-duplex by cutting 2 (ie 1 tx, 1rx) of the pairs. Specifically, the outer 2. An ethernet NIC should detect the change and fallback to 100MbE.
-
100Mbit still does full duplex
