A computer program product comprising computer executable instructions stored on a non-transitory computer readable medium such that when executed by a processor cause a service specific virtual topology base, positioned in a network stratum, to receive a virtual service negotiation initiation message from an application stratum component, wherein the initiation message comprises a plurality of network source addresses, a plurality of network destination addresses, and a service specific objective, obtain a plurality of computed network paths that traverse a network of network stratum Network Elements (NEs) between the network source addresses and the network destination addresses and meet the service specific objective, and calculate service specific virtual topology that abstractly represents the computed service specific network paths.
