CST311.5 Module Five
CST311.5 Module Five What I learned this week: This week we covered the Network Layer, and how it's essentially the glue of the network. The book breaks it down into two interacting parts, one being the data plane and the other being the control plane. for the data plane its primary focus is set toward forwarding packets, as a per router function in the network layer this means as a datagram arrives at the routers input link it is then forwarded to the appropriate output link. Where as the control plane handles the network-wide logic which is dictated by routing algorithms and in some cases Software-Defined Networking in which a remote controller broadcasts forwarding tables across the network to intended routers for their forwarding function. As can be seen the two most essential functions of the network layer are forwarding and routing of datagrams. Where the data plane is focused on forwarding and the control plane handles the routing of datagrams. Overall the Network Laye
