The Magic Behind WAN Networking: Exploring OSI's Layer 2

The OSI layer 2 or Data Link Layer provides a host of services to both the Network Layer and Layer 1. Error detection, Flow control, data organization into frame structures, synchronization, and reliability are the complex features of Layer 2. We will look at ethernet, DSL, PPP, DOCSIS 3, SONET, and more. Transfers data between adjacent network nodes! The principal service is transferring data from the network layer of the source to the network layer of the destination node. The importance of flags in the frame. We will explore frame check sequence (FCS) and Forward Error Correction (FEC). Automatic repeat Request or (ARQ) and its role in the standard ITU G.hm standard.
