source, destination, time stamps, identification codes, transmission
status, number of packets, size of message, and so on. These pieces of

information may be useful in troubleshooting problems and tracking
down unauthorized communications or used against a system as a
means to extract data about how it functions.

Transmission error correction is a capability built into connection- or
session-oriented protocols and services. If it is determined that a
message, in whole or in part, was corrupted, altered, or lost, a request

can be made for the source to resend all or part of the message.
Retransmission controls determine whether all or part of a message is
retransmitted in the event that a transmission error correction system
discovers a problem with a communication. Retransmission controls
can also determine whether multiple copies of a hash total or CRC
value are sent and whether multiple data paths or communication
channels are employed.
