This week we continued the Network Layer and introduced the Link Layer. For the network layer we covered Routing and Forwarding, Dijkstra's Algorithm, Distance Vector Algorithm and for the link layer we covered Error Detection and Correction & MAC Protocols.
Routing answers the question of what next hop IP to send a packet based on the destination prefix while forwarding functions determine which exit interface to use to send the packet to its next hop.
The Medium Access Control (MAC) protocol is used to provide the data link layer of the Ethernet LAN system.
