Transforming Network Capacity Planning From an Art to a Science

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. Without knowing what types of traffic are using the network,...
