Capacity planning is a technique that network administrators use to plan for network growth and ensure that they expand their network with equipment that will meet projected needs. Capacity planning involves most network systems, including servers, network components such as adapters and cable, switches, routers, and other equipment. It also involves network topologies-that is, planning the upgrade to switched networks over a period of time in anticipation of higher traffic rates and network-wide traffic patterns.
Capacity planning involves measuring current throughput rates. This may be done by analyzing reports and statistical information that is produced by servers and other equipment. Monitoring equipment may also be used to track network performance. Without capacity planning, administrators must deal with problems as they occur, typically by reacting to alarms that indicate that some threshold for a system has been exceeded. Capacity planning can help you deal with problems and disasters before they happen.
Third-party capacity planning tools can help. Such tools are specifically designed to help network administrators plan for the future and prevent impending disasters. They include network-mapping tools that document the network and keep track of problems. However, most important, these tools can simulate traffic on a network, which provides an administrator with a real view of how a network or parts of a network perform under pressure. You can even simulate a disaster to see where the worst problems will be in advance.

Several capacity planning and simulation tools are described below. See the related entries page for a more complete list of vendors. These packages can be expensive ($10,000 plus), but are essential for large corporate networks.
