Logical Link Control

LLC Full Form is Logical Link Control. LLC is one of the two sublayers of the Data Link Layer which is, in fact, one of the seven layers of Open Systems Interconnection (OSI) model of communication. It is a data communication protocol. It is the upper sub-layer of Data Link Protocol. The LLC is primarily and mainly concerned with multiplexing protocols that are transmitted over Media Access Control (MAC) layer and it also helps to decode them.

It also efficiently provides synchronization, acknowledgement, node-to-node flow control and ARQ (Automatic Repeat Query) error management. It manages traffic over the physical medium. The LLC header helps the data link layer to understand what to do with a datagram packet that is received. It provides addressing and control of the data link.

It determines the addressing mechanisms for the addressing stations related to the transmitting medium and controls the transmission and flow of the data exchange between the source and the destination. Line protocols like SDLC, NetBIOS, NetWare are also identified by the help of LLC. But, nowadays better technology is being introduced and hence, LLC is only being considered as a multiplexing feature in the link layer protocols. More emphasis is given upon end-to-end protocols like TCP (Transmission Control Protocol).
