Often
split into two sublayers:
|
|
|
|
ä |
MAC
sublayer: deals with sharing a common
|
|
|
channel,
as in Ethernet or Token Ring networks, is
|
|
|
empty
for networks build with dedicated point-point
|
|
connections
|
|
|
|
ä |
Logical
link control sublayer: sits on top of MAC
|
|
|
sublayer,
assumes that adjacent machines
|
|
|
communicate
over a dedicated physical or logical
|
|
|
link,
deals with:
|
|
|
|
ä |
flow
control
|
|
|

error
control

|
ä |
framing
