    Net Neutrality and Privacy

    by Andrew McCaskey
    Net Neutrality Might Lost at the Protocol Level

    The UK site Tech Radar has a very thoughtful article about how net neutrality and anononimity might be lost at the protocol level – in a move so subtle that it would slip away without notice.

    The premise is that our current TCP/IP system, by design, makes it almost impossible to tell the origin of a particular packet. But, that is not a law of nature, it is merely a byproduct of some design decisions that were made in selection of elements of the protocol within TCP/IP. Tech Radar points an accusing finger at the nascent US Air Force Cyber Command, proposing revisions to the protocol that would require tagging of packets with origin, building an audit trail of the hand off points. Packets lacking the tracking detail would be refused by cooperating routers.

    The subtlety is that this could be made optional – initially used only for government communications or official traffic. Then it could be extended to include such traffic as weather information or public safety broadcasts. Then a few years later, a phase in for filing with the Department of Motor Vehicles, or taxes. As the system became more accepted, all “modern routers” would adopt the new protocol, and fewer portions of the net would use the perfectly legal “old style” connections. Just like the ease with which we hook up DRM friendly HDMI cabling and analog ports fall into misuse, we are led along the path.
