super source quench
     
        A special packet designed to shut up an {Internet} host.  The
        {Internet Protocol} (IP) has a control message called Source
        Quench that asks a host to transmit more slowly on a
        particular connection to avoid congestion.  It also has a
        Redirect control message intended to instruct a host to send
        certain packets to a different local router.  A "super source
        quench" is actually a redirect control packet, forged to look
        like it came from a local router, that instructs a host to
        send all packets to its own local loopback address.  This will
        effectively tie many Internet hosts up in knots.  Compare
        {godzillagram}, {breath-of-life packet}.
