Metric = [K1 * Bandwidth + (K2 * Bandwidth)/(256-load) + K3*Delay] * [K5/(reliability + K4)]
This is the IGRP metric calculation. Defualt values are:
K1 = 1
K3 = 1
K2 = 0
K4 = 0
K5 = 0.
I quote
"If K5 = 0, the [K5/(reliability + K4)] term is not used. So, given the default values for K1 through K5, the composite metric calculation used by IGRP reduces to Metric = Bandwidth + Delay."
What do they mean that "the [K5/(reliability + K4)] term is not used."? Does the software run an if statement and use two different versions of the formula depending on the value of K5? I'm asking because I'm fairly sure that if you substitute the default values in to the above expression as it stands, then the answer will ALWAYS be zero.
