In recent years, due to the increase of network users, network resources wasting on a global scale is becoming more serious. Traditional resource scheduling policy can not meet the current allocation of network resources; we propose a SDN resource scheduling strategy based on bilateral market three-tier pricing mechanism. Respectively, each layer of the three-tier pricing mechanism integrates into the three-tier architecture of the SDN, and introduces the concept of a bilateral market, changing SDN resource scheduling into a commodity trading in economics.
