Hi Eoghan and every body; Please i am blocked on one point. I need to know some mapping formulas. For example the QoS availability is calculated through the low level metric uptime and downtime. And the used formulas is: availability = 1- (uptime/downtime+uptime). Please whom know others formulas to calculate others QoS through low level. For example: Throughput??? Reliability??? Cost???
