- We have seen in AIMD for a single flow that R = W(t) / RTT(t). In the case of multiple flows, RTT(t) tend to be constant. So the sending rate varies with the window size:

**R = W(t) / RTT** and it tends to equal W(t)

- The queue occupancy
**B**for multiple flows has a smooth geometric intuition and is almost constant in time, compared with the queue occupancy for a single flow.

- AIMD is sensitive to packet loss, since R can be written as a function of
**p**, p being the**drop probability**:

** R = √(3/2) * 1/(RTT*√p)**

Regarding packet loss, remember that lost packets on one flow do not impact another flow.
