Open publisher page 0 citations

Abstract

The network bandwidth optimal allocation mechanism in new generation network is investigated in this paper.The fairness aware flow utility function is constructed by using the social welfare function and the elastic flow's priority,the Nash Equilibrium of the network bandwidth optimal allocation model is proved,and the bandwidth optimal allocation mechanism on flow's priority is poprosed.Simulation result shows the proposed mechanism not only can achieve differentiated services according to the priority,but ensures the relative fairness of the bandwidth allocation as well,thus guarantees the QoS of different service flow.
