[altq 33] ALTQ/CBQ calculations

[G Muthukumar <muthu@wipro.wipsys.soft.net>]

Hi all,

	I recently started going thru the source code for ALTQ (and CBQ) and 
came across the function cbq_class_spec (rsvp_cbq.c). I came across few 
calculations in this function which I am not able to understand how they 
are derived:

	1. cptime = ptime * (1.0 - f) / f;
	2. maxidle = ((1.0 / f - 1.0) * ((1.0 - gton) / gton));
	3. offtime = cptime * (1.0 + 1.0/(1.0 - g) * (1.0 - gtom) / gtom);

	I am sure there is some basis for these calculations.

	Could you please help me understand these calculations?

Thanks,
Muthu
