A dynamic limitation mechanism for flow-aware networks

Measurement-based admission control routine in Flow-Aware Networks often leads to fair rate degradation, which negatively impacts the performance of ongoing flows. This problem can be solved with the limitation mechanism, however, only if properly configured. When the limitation mechanism is badly configured or the network conditions change rapidly the mechanism does not help, and sometimes, it can even exacerbate the problem. This paper shows that it is possible and more efficient to provide dynamic limitations, where the admission limit is not static, but dynamically calculated. It is shown that the proposed mechanism provides better results and is more robust. Also, the issue with configuration is diminished, since the mechanism automatically adapts to the current network congestion level.
