Payload Type, the essential data that is being carried within a packet or other
transmission unit. The payload does not include the "overhead" data required to get
the packet to its destination. Note that what constitutes the payload may depend on
the point-of-view. To a communications layer that needs some of the overhead data to
do its job, the payload is sometimes considered to include the part of the overhead
data that this layer handles. However, in more general usage, the payload is the bits
that get delivered to the end user at the destination.
