Bandwidth limitations continue to play a significant role in application performance. Most WANs fall into one of two main categories. The first category includes lowerspeed networks such as dial up, frame relay, and many mobile data networks. These networks often range in speed from 56 Kbps to 2 Mbps and have many endpoints. While not suitable for large offices, these data rates are common among small branch offices. The second category is high-speed networks that range in speed from 45 Mbps to 622 Mbps; these are typically used for data replication and communication between large offices.
