In packet switched communication networks

traffics between any source destination（SD） pair are expected to be transmitted over multiple paths.In this paper

we focus on the problem how to optimally distribute the load on a set of alternative paths so that the average time delay of a packet can be minimized.Since real time processing of this problem is needed in most cases

we propose a neural network method to solve it.Experiments on a typical communication network demonstrate that the result obtained using our method is better than the best result yielded by other rigorous mathematical algorithms.
