...functions placed at low levels of a system may be redundant or of
little value when compared with the cost of providing them at that low
level. Examples discussed in the paper include bit error recovery,
security using encryption, duplicate message suppression, recovery from
system crashes, and delivery acknowledgement. Low level mechanisms to
support these functions are justified only as performance enhancements. -
