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]
