The unreasonable allocation scheme of bandwidth resources is a serious problem in the opening Internet.To restrict the users’ selfishness

a network bandwidth allocation mechanism based on VCG(Vickrey-Clarke-Groves) auction is proposed

which has the dominated strategy incentive compatible property.A discrete stochastic learning algorithm which is used to guide the users to choose strategies is introduced and its convergence is analyzed further.Simulation results show that the selfish users do not have any incentives to lie and provide the real bandwidth requirements

through the effective punishment scheme;the discrete stochastic learning algorithm can make the users select the dominate strategy correctly and allocate the bandwidth resources reasonably.
