A general dimensioning method and system for allocating limited transmission resources to virtual paths and virtual networks on a physical network given offered traffic on each virtual path or virtual link. A hierarchical structure is defined with a layer of one or more virtual paths on top of a layer of physical network elements, and optionally, an intermediate layer of virtual networks. The virtual path dimensioning problem is solved using the Entropy Rate Function as a blocking measure. The loads on the various links are balanced by equalizing blocking probabilities and the optimal allocation of physical resources is determined. |
