Adaptive Coding and Packet Rates for TCP-Friendly VoIP Flows
... In general, TCP-friendly rate control algorithms are not suitable for the transmission of voice flows that need to transmit small packets. For this reason we suggest two alternate solutions which are suitable to improve the fairness. First, small packets can be treated differently in the router, e.g ...
