By Dinesh Thakur. Data link layer is the second layer in OSI reference model and lies above the physical layer. The physical layer provides only a raw bitstream service between computers. The data link layer provides data reliability and provides tools to establish, maintain, and release data link connections among the network nodes.

The data link layer ensures reliable delivery of the frames from source to destination. For that, it adds the checksum bits to the frames. On the receiver, the checksum bits are again calculated from the received frame. If checksum bits are different from received, the fame is marked as corrupted, and the sender will retransmit the same frame.

For Layer 2 functions, Ethernet relies on logical link control (LLC) and MAC sublayers to operate at the data link layer. FCS (Frame Check Sequence) and SFD (Start Frame Delimiter) are fields of the Ethernet frame. CSMA (Carrier Sense Multiple Access) is the technology Ethernet uses to manage shared media access. This document reviews the architectural design of the transport layer. In particular, this document proposes to separate the transport layer into two sublayers; the data path and the data flow layers. The data path layer provides functionality on the data path, such as connection handling, path quality and trajectory monitoring, waypoint management, and congestion control.

In this tutorial, we will be covering the Multiple access in the Data link layer of the OSI Model.
