A mechanism of routing and wavelength assignment in Dense Wavelength Division Multiplexing (IP / DWDM) Optical Internet is proposed. The Multi-Agent Evolutionary Algorithm (MEA) algorithm and the Joint First Fit (JFF) algorithm are introduced This paper introduces the unicast routing and wavelength assignment of QoS (Quality of Service) .It introduces the knowledge of probability theory to deal with the uncertainty of the link state parameters, introduces the knowledge of fuzzy mathematics to provide the flexible quality of service (QoS) support, Game theory and microeconomics to construct a fair link pricing method, which makes the network providers and users’ utilities reach the Pareto optimality at or near the Nash equilibrium.The simulation results using VC ++ 6.0 as a development tool show that, The proposed mechanism can effectively solve the problem of QoS unicast routing and wavelength assignment in IP / DWDM optical Internet and has good performance.
