The notional "kiss-of-death packet", with a function complementary to that of a breath-of-life packet, is recommended for dealing with hosts that consume too many network resources. 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.
