Therefore, it’s impractical to do capacity planning, and we should continue to provision bandwidth to deal with performance problems.”

Regardless of the planning methodology used, it’s important to measure network performance in order to manage it. Network troubleshooters need real-time utilization and error data. The help desk needs to view performance data ...
