Data Link Connection Identifier definition
<networking> (DLCI) A channel number which is attached to
data frames to tell a Frame Relay network how to route the
data. In Frame Relay, multiple logical channels are
multiplexed over a single physical channel. The DLCI says
which of these logical channels a particular data frame
belongs to.

data link layer definition
<networking> Layer two, the second lowest layer in the OSI
seven layer model. The data link layer splits data into
frames (see fragmentation) for sending on the physical
layer and receives acknowledgement frames. It performs error
checking and re-transmits frames not received correctly. It
provides an error-free virtual channel to the network layer.
The data link layer is split into an upper sublayer, Logical
Link Control (LLC), and a lower sublayer, Media Access
Control (MAC).
Example protocols at this layer are ABP, Go Back N,
SRP.

Data Link Provider Interface definition
<networking> (DLPI) The interface that a network driver
presents to the (higher level) logical link layer for
driving the network at the datagram level in a Unix
STREAMS environment and possibly elsewhere.
DLPI corresponds to ISO 8802/2 (LLC) which covers both
connection-oriented and connectionless protocols.
[Is this correct? Better explanation?]
