Page "Data link layer" Paragraph 6

In some networks, such as IEEE 802 local area networks, the data link layer is described in more detail with media access control ( MAC ) and logical link control ( LLC ) sublayers ; this means that the IEEE 802. 2 LLC protocol can be used with all of the IEEE 802 MAC layers, such as Ethernet, token ring, IEEE 802. 11, etc., as well as with some non-802 MAC layers such as FDDI.

Other data-link-layer protocols, such as HDLC, are specified to include both sublayers, although some other protocols, such as Cisco HDLC, use HDLC's low-level framing as a MAC layer in combination with a different LLC layer.

In the ITU-T G. hn standard, which provides a way to create a high-speed ( up to 1 Gigabit / s ) local area network using existing home wiring ( power lines, phone lines and coaxial cables ), the data link layer is divided into three sub-layers ( application protocol convergence, logical link control and medium access control ).
