Abstract
This paper proposes a new approach to modelling and controlling Internet end-to-end loss
behaviours. Rather than select the model structure from the loss observations as being done
previously, we construct a new loss model based on the TCP congestion control mechanisms.
Thus, the model can explicitly reflect the correlation between end-to-end loss observations and
network flow level activities. Besides simulation, the model has been tested in both wired and
wireless Internet environments. The result shows that, unless the losses due to the transmission
errors are excessive e.g. in some lossy wireless channels, the model can correctly capture
end-to-end loss behaviours not only in terms of average rates but also in terms of loss patterns i.e.
loss and good runlengths. This implies a good connection between the model structure and
network flow level activities, which makes the model attractive for assisting network traffic control.
