<P> 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 provides multiplexing mechanisms that make it possible for several network protocols ( e.g. IP , IPX , Decnet and Appletalk ) 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 . </P>
