Lecture - Tuesday, October 1st.

16-19 in U45

We will start our treatment of the network layer.

We will cover the data plane part of it. This includes an introduction to the network layer, studying whats inside a router, how it does the internal switching of datagrams, the IP protocol (IPv4 and IPv6), DHCP, addressing and Network Address Translation.

The goal is to cover the entire chapter 4 (it is half of the network layer, chapter 5 is also on the network layer)

I will also share and discus items from the mid-term evaluation.
