Abstract: QoS requirement is denoted by the range to support the flexible and heterogeneous QoS.According to the microeconomics theory and method,a Kelly/PSP model-based pricing strategy was presented to support the inter-group fairness.The ELSD(Equal Link Split Downstream) method was adopted to apportion the cost among group members,thus the intra-group fairness was provided.Based on the parallelized FCNN(Firing Coupled Neural Network),a parallel and intelligent QoS multicast routing algorithm was introduced,exploiting the inherent parallelism in FCNN fully and improving the scalability to the network size and the problem complexity significantly.Combining the above,a parallel,fair and intelligent QoS multicast routing mechanism was established.Simulation results have shown that the proposed mechanism is both effective and efficient,and the runtime efficiency of the proposed parallelized algorithm is higher than its corresponding serialized one.
