Chapter Outline
Note: We are going to spend 2 to 3 class periods on the Network and Transport layer. It is where MOST of the business of Networking takes place and there is a lot to the Network and Transport layers. We will learn about the functions of the Network Layer, the TCP/IP protocol, all of its parts, how to calculate subnets, how packets are transmitted, and the common Network port to application protocol mappings. We will learn about NAT (network address translation), and then revisit nat in the Security lecture.
