In this paper, a new optimal routing algorithm to minimize packet loss in high-speed networks is proposed. In high-speed networks, such as ATM networks, packets could be lost while being routed to their destinations. Minimization of packet loss probabilities becomes a major concern. The optimal routing problem (ORP) minimizing average network packet loss probabilities is more complicated since the ORP is a non-convex problem and the ordinary gradient projection algorithm can not be directly used to achieve optimal routing. To solve the packet loss ORP, we developed an HAD based two-stage algorithm, which can effectively avoid the traps of local minimum caused by the non-convexity of the problem and thus, can find the true optimal solution of the ORP with high computation speed.
