| In this paper we present a TCP-friendly
congestion control scheme for non-adaptable flows. The main
characteristic of these flows is that their data rate is
determined by an application and cannot be adapted to the current
congestion situation of the network. Typical examples of
non-adaptable flows are those produced by networked computer
games or live audio and video transmissions where adaption of the
quality is not possible (e.g., since it is already at the lowest
possible quality). We propose to perform congestion control for
non-adaptable flows by suspending them at appropriate times so
that the aggregation of multiple non-adaptable flows behaves in a
TCP-friendly manner. The decision whether a flow is to be
suspended is based on random experiments. In order to allocate
probabilities for these experiments, the data rate of the
non-adaptable flow is compared to the rate that a TCP flow would
achieve under the same conditions. We present a detailed
discussion of the proposed scheme and evaluate it through
extensive simulations with the network simulator ns-2. |
