A virtual network mapping algorithm based on subgraph isomorphism detection

  title={A virtual network mapping algorithm based on subgraph isomorphism detection},
  author={Jens Lischka and Holger Karl},
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. The contribution of this paper is a Virtual Network Mapping (VNM) algorithm based on subgraph isomorphism detection: it maps nodes and… CONTINUE READING
