Cosa (chi) è Logical Link Control - definizione
SUBLAYER OF THE OPEN SYSTEMS INTERCONNECTION MODEL
Logical Link Control; IEEE 802 LLC; 802 LLC
Logical Link Control
<networking> (LLC) The upper portion of the data link layer,
as defined in IEEE 802.2. The LLC sublayer presents a
uniform interface to the user of the data link service, usually
the network layer. Beneath the LLC sublayer is the {Media
Access Control} (MAC) sublayer.

Logical link control
In the IEEE 802 reference model of computer networking, the logical link control (LLC) data communication protocol layer is the upper sublayer of the data link layer (layer 2) of the seven-layer OSI model. The LLC sublayer acts as an interface between the media access control (MAC) sublayer and the network layer.
Link Control Protocol
COMPUTER NETWORK PROTOCOL
Logical control protocol; Link control protocol
<protocol> A protocol used to automatically agree upon
encapsulation format options, handle varying packet size
limits, authenticate the identity of its peer on the link,
determine when a link is functioning properly and when it is
defunct, detect a looped-back link and other common
misconfiguration errors, and terminate the link.

Logical link control
In the IEEE 802 reference model of computer networking, the logical link control (LLC) data communication protocol layer is the upper sublayer of the data link layer (layer 2) of the seven-layer OSI model. The LLC sublayer acts as an interface between the media access control (MAC) sublayer and the network layer.
The LLC sublayer provides multiplexing mechanisms that make it possible for several network protocols (e.g. IP, IPX and DECnet) to coexist within a multipoint network and to be transported over the same network medium. It can also provide flow control and automatic repeat request (ARQ) error management mechanisms.
