Design Utilization Rates

The facility utilization goal for the network should be 70 percent of capacity
for the line rate over the time period desired. The time period that should be used is a nine month sliding window that needs to be briefly
revisited on a monthly performance report, and then during a quarterly
design review, following the design review guideline process.
The facility will need to be expanded once it is understood that the 70-
percent utilization level will be exhausted within 9 months with continued
growth showing exhausting, 100 percent, within 18 months.
For the packet-switched network, the following should be used as the
general guidelines:
■ Processor occupancy 70-percent
■ Switching platform SCR (25-percent), PCR (90-percent)
■ Port capacity Design for 70-percent port utilization (growth
projection for additional ports based on nine-month forecast) 513
