[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.
