Abstract

The present disclosure generally discloses a network infrastructure virtualization mechanism configured to support virtualization of the network infrastructure (NI) of a communication network to provide thereby a virtualized infrastructure (VI) for the communication network. The network infrastructure virtualization mechanism may be configured to support virtualization of infrastructure resources (IRs) of the network infrastructure to provide virtualized infrastructure resources (VIRs) of the network infrastructure. The IRs of the communication network may include network resources (NRs) which may be virtualized to provide virtualized network resources (VNRs) and service resources (SRs) which may be virtualized to provide virtualized service resources (VSRs). The network infrastructure virtualization mechanism may be configured to support multi-owner virtualization such that multiple owners may share portions of the network infrastructure of the communication network and multi-tenant virtualization such that multiple tenants, at one or more hierarchical layers, may share portions of the network infrastructure of the communication network.
