On the basis of describing the optimization of the multicast routing with QoS constrained,the paper presents a new approach based on the Hopfield model of artificial neural networks to solve the routing problem in the distribut-ed computer networks design.The simulation result shows that the routing algorithm is better by virtue of its better dis-tribution and intelligent decision ability.The scheme not only guarantees the bandwidth,end-to-end delay and delay-jin-ter,optimizing the cost of the routing tree,but also efficiently controls the algorithm complexity for large size of network.As a result,the proposed neural-network approach is suitable to be integrated into overall topological design processes,for moderate and high-speed networks subject to quality of services constraints as well as to changes in configuration and link costs.
