Setting up a connection is easy. Setting up a connection that meets the objectives behind having a connection can be a lot harder.
If a WAN requirement exists, it should have specific uses identified. In determining the WAN parameters, you willneed to understand the tasks being accomplished over it in terms of both individual task traffic and aggregate task traffic. Next, look at the impact of latency and bandwidth constraints. Some applications developed on and for LAN environments fail when the WAN constraints come into play. Latency is often the bigger factor - sessions time out before completing. Bandwidth primarily impacts volume.
Many small businesses will find that rather than a WAN, an xSP provides a better solution. For example, hosting email and using the Internet for access by users, or using a Web portal versus a corporate platform for data entry.
