Routing and congestion control in ATM networks

A new routing and, performed by the leaky bucket regulators, congestion control strategy in ATM networks is proposed. The “potential” source provides the network with its characteristics and required quality of service. Based on this information, the network makes the admission and routing decisions and selects parameters of the leaky bucket “regulators” reinforcing the contract. The strategy minimizes the weighted average delay in the network, subject to the constraints on the average delays for the individual sessions and on the nodes buffers´ overflow probabilities
