3.8. Summary
In this chapter, we began by discussing the anatomy of an Ethernet frame and how systems on a local Ethernet segment communicate. We also covered how routing is used to assist communication in large networking environments. From there we looked at the different methods of connection establishment and finished off the chapter by discussing IP services.
In the next chapter, we will begin to look at some of the insecurities involved in everyday communications. We will look at how building security into your core network design can not only improve performance (always a good thing)—it can make your data less susceptible to attack, as well.
