What does the network layer do? Where does it sit in relationship to the other four layers of our simplified network model? Network layer is the third layer of the OSI model. It performs switching and routing by creating logical paths‚ known as virtual circuits‚ for transferring data from one node to another node. Routing and forwarding are the major functions of this layer. It also performs other operations such as addressing‚ internetworking‚ error handling‚ congestion‚ control and packet
