Logical Link Control

According to the IEEE 802 family of standards, Logical Link Control (LLC) is the upper sublayer of the OSI data link layer. The LLC is the same for the various physical media (such as Ethernet, token ring, and WLAN).The LLC sublayer is primarily concerned with: Multiplexing protocols transmitted over the MAC layer (when transmitting) and demultiplexing them (when receiving).Providing flow control and detection and retransmission of dropped packets, if requested.The protocol used for LLC in IEEE 802 networks and in some non-IEEE 802 networks such as FDDI is specified by the IEEE 802.2 standard.

<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.
