Average Peak Rates

 

This section describes the average peak rates.

For example, with one million subscribers, 20 percent of them operate the call model (as described in Table 8) during the daytime peak hours. This is up to 200,000 sessions over 6 hours, or 33,333 sessions per hour, or 556 sessions per minute, or 10 sessions per second. To manage this load on average, you need to do 130 Oracle transactions per second, 230 NDB hits per second, plus 10 TTLS and 10 resumptions per second, plus 140 accountings per second. However, the assumption of a constant task flow at an average rate is not entirely valid; you will generally see that the spikiness in call processing exceeds the low average figure (see Spike Rates at Peak).
