WAN data communications encompass broad geographically dispersed areas facilitated by transmission services of common carriers, as depicted in Figure 3.5. WAN technologies generally function at layers 1 through 3 of the OSI TCP/IP reference model, which is why most network engineers also function at this level.

To at least some extent, WANs are defined by their methods of transmitting data packets. True, the means of communication must be in place. True, too, the networks making up the WAN must be up and running. And the administrators of the network must be able to monitor traffic, plan for growth, and alleviate bottlenecks.
