DDR的用处 Headquarters Telecommuter Vendor 周期连接 少量数据 * Purpose: This figure explains when one would want to use DDR. Emphasize: DDR is used for low-volume, periodic connections when traffic demands do not dictate the use of a dedicated line. DDR addresses the need for periodic network connections over a circuit-switched WAN service. By using WAN connections only on an as-need basis, DDR saves WAN-usage costs. Note: Provide some scenarios when DDR may be used.
