The WAN connections provided by standard asynchronous modems and ISDN are gen erally slower than leased lines sometimes much slower but they have one great advantage. Because these are dial-up services, you can disconnect them at will, and use them to connect to different destinations. The ability to disconnect means that you are paying for only the bandwidth you are using. Both standard telephone lines and ISDN connections typically have a per-minute charge in addition to a monthly fee, so disconnecting during off hours can result in substantial savings.

The ability to connect to different destinations by dialing alternative numbers can have a profound effect on your internetwork design, particularly when you use the dial-ondemand feature incorporated into Windows Server 2003 Routing and Remote Access and into many other routers. Dial-on-demand enables a router to connect to a remote network only when a computer sends traffic to a destination on that network.

You can install a Windows Server 2003 router with an ISDN line at a branch office and configure it to remain idle until someone in the office requires access to a resource at the corporate headquarters. When a user attempts to access a remote resource, the router dials the appropriate number, connects to the headquarters network, and begins routing data. Once the transmissions are completed and the ISDN connection has been idle for a specified interval, the router drops the con nection until someone needs it again. For WAN technologies that charge by the minute, dial-on-demand prevents you from paying for bandwidth your network is not using, without requiring manual intervention from administrators. The other advantage of dial-on-demand is that you can use a single dial-up connection to access multiple remote sites. For an organization with ten locations, a mesh topology of WAN connections might be completely impractical using leased lines, but by using a single ISDN line with dial-on-demand at each office, any network can connect to any other network, as needed, simply by dialing the appropriate number. There are drawbacks to this arrangement; for example, each network can connect to only one other network at a time, but for situations where networks need only occasional remote access, dial-on-demand can be an effective and economical solution.

Using Frame Relay
Frame relay is a popular WAN technology because it provides both flexibility and econ omy. A frame relay connection consists of a standard leased line linking the network site to the frame relay provider s nearest point of presence (POP). The provider then furnishes the connection to the frame relay cloud. When you use a frame relay pro vider for a private network-to-network connection, you must install a leased line at each site that connects the network to the provider s nearest POP. The provider then connects both lines to the same cloud, so that the networks can establish a link.

A private frame relay connection provides the same benefits as a frame relay Internet connection, such as the ability to pay for only the bandwidth you use, and the ability to exceed your contracted bandwidth during heavy traffic periods. In addition, if you select the right provider, frame relay enables you to connect each of your sites to a local POP, reducing the cost of the leased lines. Another major benefit is the ability to connect to multiple sites using a single frame relay connection. You can actually create a mesh topology among all the networks in your enterprise by using a single leased line at each site to connect to a common cloud. Because connections in a frame relay cloud are ephemeral, a single network can simultaneously establish multiple links to different destinations (see Figure 5-5).
