Lecture 1: Networking Introduction

This lecture will introduce the course, with information about logistics, texts, staff, grading, etc. After that, we will skim through the course, getting a feel for how networks work. We will discuss two ways of modeling the internet. The first model is to look at the pieces that make up the network. By composing these “nuts and bolts,” we can get a good idea of how communication happens. The second modeling method is to think about the various services that are provided and describe the network as a mechanism for providing such services. Finally, we will describe the differences between the network edge and the network core.
