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.[Jargon File]
