Communication in OSI model
 At each level, two entities (N-entity peers)
interact by means of the N protocol by
transmitting protocol data units (PDU).
 A service data unit (SDU) is a specific unit
of data that has been passed down from an
OSI layer to a lower layer, and which the
lower layer has not yet encapsulated into a
protocol data unit (PDU). An SDU is a set of
data that is sent by a user of the services of
a given layer, and is transmitted
semantically unchanged to a peer service
user.
 The PDU at a layer N is the SDU of layer N1. In effect the SDU is the 'payload' of a
given PDU. All the data contained in the
SDU becomes encapsulated within the
PDU. The layer N-1 adds headers or
footers, or both, to the SDU, transforming
it into a PDU of layer N-1. The added
headers or footers are part of the process
used to make it possible to get data from a
source to a destination.
