- breath-of-life packet — (XEROX PARC) An Ethernet packet that contains bootstrap code, periodically sent out from a working computer to infuse the "breath of life" into any computer on the network that has crashed.

Though "kiss-of-death packet" is usually used in jest, there is at least one documented instance of an Internet subnet with limited address-table slots in a gateway computer in which such packets were routinely used to compete for slots, rather like Christmas shoppers competing for scarce parking spaces.
