Function Documentation

u32 tfrc_calc_x	(	u16	s,
		u32	R,
		u32	p
	)

tfrc_calc_x - Calculate the send rate as per section 3.1 of RFC3448 : packet size in bytes : RTT scaled by 1000000 (i.e., microseconds) : loss ratio estimate scaled by 1000000

Returns X_calc in bytes per second (not scaled).

u32 tfrc_calc_x_reverse_lookup

(

u32

fvalue

)

tfrc_calc_x_reverse_lookup - try to find p given f(p) : function value to match, scaled by 1000000

Returns closest match for p, also scaled by 1000000

u32 tfrc_invert_loss_event_rate

(

u32

loss_event_rate

)

tfrc_invert_loss_event_rate - Compute p so that 10^6 corresponds to 100% When is large, there is a chance that p is truncated to 0. To avoid re-entering slow-start in that case, we set p = TFRC_SMALLEST_P > 0.
