Abstract: A method for policy-aware mapping of an enterprise virtual tenant network includes receiving inputs from a hosting network and tenants, translating resource demand and policies of the tenants into a network topology and bandwidth demand on each link in the network; pre-arranging a physical resource of a physical topology for clustering servers on the network to form an allocation unit before a VTN allocation; allocating resources of the hosting network to satisfy demand of the tenants in response to a VTN demand request; and conducting a policy aware VTN mapping for enumerating all feasibly resource mappings, bounded by a predetermined counter for outputting optimal mapping with policy-compliant routing paths in the hosting network.
