A Fair and Intelligent QoS Multicast Routing Mechanism in IP/DWDM Optical Internet
IP/DWDM光Internet中的一种公平智能QoS组播路由机制

QoS (Quality of Service) and multicast are essential capabilities in IP/DWDM optical Internet. In this pa- per, a fair and intelligent QoS multicast routing mechanism in IP/DWDM optical Internet is discussed. In the proposed mechanism, QoS requirement is denoted by an range to support the flexible and heterogeneous QoS, according to the microeconomics theory and method, a Kelly/PSP-model-based pricing strategy is presented to support the inter-group fairness; the ELSD (Equal Link Split Downstream) method is adopted to apportion the cost among group members, thus the intra-group fairness is provided; based on FCNN (Firing Coupled Neural Network) , an intelligent QoS multi- cast routing algorithm is introduced. Combining the above, a fair and intelligent QoS multicast routing mechanism is es- tablished. Simulation results have shown that the proposed mechanism is both effective and efficient.
