Research and implementation of the SDN resources transaction process based on trust mechanism

SDN network as new network architecture, can address a range of issues of the current internet effectively, this paper in the view of SDN network resources' allocation, for decreasing resources waste and achieving a reasonable distribution of SDN resources, come up with a suitable resource price negotiation algorithm based on trust mechanism in SDN network environment. According to the characteristics of the trust mechanism, simulating on the unit utility and equivalent price of SDN network resources in three aspects (remove individual malicious nodes, remove most malicious nodes and remove all malicious nodes), through the above simulation, combined trust mechanism with MCDAM algorithm, can form a weighing system which pricing and trust comprehensive competitive, so that the whole SDN trading environment become safer and more stable. So trust mechanism as the patch of SDN pricing negotiation algorithm. Finally, propose the planned trading model based on trust mechanism as a management method of SDN trading.
