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.
