A virtual network mapping algorithm based on subgraph isomorphism detection
Jens Lischka, Holger Karl · 2009
Assigning the resources of a virtual network to the components of a physical network, called Virtual Network Mapping, plays a central role in network virtualization. Existing approaches use classical heuristics like simulated annealing or attempt a two stage solution by solving the node mapping in a first stage and doing the link mapping in a second stage.
