breath-of-life packet
 n.

    [XEROX PARC] An Ethernet packet that contains bootstrap (see boot) code,
    periodically sent out from a working computer to infuse the ?breath of
    life? into any computer on the network that has happened to crash. Machines
    depending on such packets have sufficient hardware or firmware code to wait
    for (or request) such a packet during the reboot process. See also 
    dickless workstation.

    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 machine in which such packets
    were routinely used to compete for slots, rather like Christmas shoppers
    competing for scarce parking spaces.

   (XEROX PARC) An Ethernet packet that contains
