Chapter 10. EXPANDING A LAN WITH WAN TEC... > Understanding Switched Networks

Understanding Switched Networks

Another WAN alternative for moving data between different LAN sites is switched network technology. A switched network allows multiple users to take advantage of the same line. This makes the overall cost of this WAN technology cheaper than dedicated leased lines.

On a switched network, your LAN (or your multiple LANs at different locations, if your company is connecting multiple sites) is connected to the wide area network by a switched network service provider or the POTS. Data leaving your LAN through the WAN connection enters the switched network and then makes its way to the final destination. The path that the data takes, however, can be different each time. This means that many different users can take advantage of moving data on the switched network almost simultaneously.
