A routing scheme generates a selection of precomputed routes that provide a wide range of available bandwidths while keeping delay (e.g., measure by cell transfer delay and cell delay variation), or cost, to a minimum, thus enabling high call rates at an overall lower call blocking rate. The routing scheme achieves this end by generating routes using a set of preconfigured bandwidth thresholds for pruning lower bandwidth links while least-cost optimizing on delay-based optimization functions, using for example, maximum cell transfer delay and maximum cell rate, or a cost-based function, using for example, administrative weight. The optimization function is determined during configuration by the selection of either cost-based or delay-based routing.
