When packet loss occurs while in slow start, does the reno/newreno algorithms notice possible dupacks, or is it purely slowstart -> rto?
Thus, if sending two packets (in start of slow start), and first one goes missing, does slow start do anything else but rto?
It is confusing, since rfc states that 'in practice they (slow start & congestion avoidance) are implemented together'. And linux source is a bit thick read and only one implementation.
