Abstract: ATM routing with Hopfield networks is studied, By taking advantage of the concept of equivalent capacity, Hopfield networks is employed for optimal routing. Further more, we proposed dual routing mode which combines many features, such as a very good convergence, a relatively low programmingcomplexity and an ability to operate in real time. The simulation result shows that call block rate is greatly reduced under different network topologies and various traffic patterns.

Key words: Hopfield networks, ATM networks, router selecting, equivalent capacity
