[Freedombox-discuss] Without software collusion

As I understand it, while the data still comes over ethernet or WiFi, it is not further routed up the layer stack beyond the hardware medium layer itself.

For example, the vPro-enabled sender will inject ethernet or WiFi traffic into the conveyance medium (copper or air) just like normal.  However, the vPro-enabled receiver will see the packet marked as vPro-out-of-band, and not send it further up the chain, but instead will intercept it and handle it internally.

So ... my question is ... will a $25 consumer router route all data sent to it without regards to this vPro out-of-band tagging?  I assume it will, be it in the form of ethernet or WiFi.

Best regards,
Rick C. Hodgin
