Abstract

The present disclosure discloses infrastructure resource states which may be configured for use in managing both infrastructure resources (IRs) and virtualized infrastructure resources (VIRs). The new resources states may include a Network Unequipped (NU) state, a Network Equipped (NE) state, a Network Ready (NR) state, a Service Ready (SR) state, an Out-of-Service (OOS) state, and an In-Service (IS) state. The infrastructure resource states may be configured to enable resource transfers in a programmable virtual infrastructure having one or more tenants (e.g., Owners, BUs, Partners, Customers, or the like) at one or more hierarchical layers. The infrastructure resource states may be configured to support VIR management for multi-owner virtualization such that multiple owners may manage resource allocation 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.
