<p>A recursive path computation method is disclosed to integratedly manage resources required for a computation of a data transmission path in a multi-layer transport network to enable automatic real time allocation of lower layer resources required for processing a path request when resources required for a path computation of each layer are not sufficient or when resources have not been previously allocated. A network path request service over multiple layers can be quickly performed, and utilization efficiency of network resources can be maximized.</p> |
