The last model has individual hotspot operators join forces and agree on roaming conditions and credential verification methods. Examples of the latter are FON and the Wi-Fi roaming infrastructures that many schools worldwide participate in— eduroam. ”) Verification of the credentials of the users at the home network requires transporting the credentials to the home network and sending the outcome of the authentication back to Chapter 3: Nomadicity the visited network. The dominant transport protocol for transporting the credentials is RADIUS.
Hosts (a traditional term for all computers that are connected to a network) are connected to one or more of these smaller networks. Routers are a special type of hosts that are connected to more than one network and that forward data from one network to the other, as illustrated in Figure 2-1. Two hosts from different networks that want to communicate with each other do so by using the TCP/IP protocol suite, so named after two of the most important protocols in that suite, TCP and IP (explained in more detail later in this chapter).
There is a need to control access to the local network and the Internet in a scalable and efficient way. A similar reasoning holds for application access. Users need to be able to access their networked applications, regardless of where they are. An increasingly popular phenomenon is that of offering applications “in the cloud,” meaning that the application is hosted or offered by a third party somewhere on the Internet. These are examples of the need for authentication, authorization, and accounting (AAA) mechanisms to control which persons or devices can gain access to the network and what they are allowed to do on that network.
