Of all the issues faced by enterprise companies in managing their networks, capacity planning is one of the most important. More an art than a science until recently, network capacity planning is all about balancing the need to meet user performance expectations against the realities of capital budgeting. WAN bandwidth is expensive. Many companies - and Cisco Systems is no exception - attempt to control costs by acquiring the minimum bandwidth necessary to handle traffic on a circuit. As recently as 2000, Cisco relied almost exclusively on Simple Network Management Protocol (SNMP) to monitor overall WAN bandwidth utilization. Measuring overall traffic, however, does little to characterize network traffic, which is essential to deciding if additional capacity is warranted.
