SummaryThis paper studies achieving the desired balance between the resource economic efficiency and user fairness in network traffic rate allocation management. Fairness is a basic requirement of different competing traffic users, while maximizing the economic efficiency of traffic rate resource is desired by the network system resource provider. Hence, how to balance these two respects to achieve the desired trade‐off is a key challenging issue in real applications. Particularly, we propose a weight mechanism to specify the rate allocation weight ratio among different competing traffic users and also a trade‐off factor mechanism to clarify the extent of fairness compromise. To optimize the system rate resource economic efficiency, we formulate an objective optimization problem with consideration of both user weight diversity and fairness trade‐off as well. We also derive the balance curve, which shows the rate resource economic efficiency improved in relation to the extent of traffic user fairness trade‐off. The demonstration models are also constructed to implemented to implement both the trade‐off acceptable and unacceptable cases in practical traffic rate resource allocation applications.
