A network device includes at least one processor, a storage device and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the network device to: write data to the storage device; replicate the data at one or more remote network devices via at least one deterministic transmission medium; and output an acknowledgement in response to determining that the data has been written to the storage device prior to receiving confirmation of successful replication of the data at the one or more remote network devices. The methods, systems or computer readable mediums leverage the deterministic and measurable nature of the transmission media to reduce the Recover Point Objective durations.

Methods, devices, systems, and computer-readable mediums for reduced recovery point objective duration

The present disclosure generally discloses capabilities for supporting new network zones and associated services. The network zones and associated services may include a near-real-time (NRT) zone and associated NRT services, a real-time (RT) zone and associated RT services, or the like. The resilient network zones and associated resilient and non-resilient services may be configured to provide bounded latency guarantees for reliably supporting various types of applications (e.g., mobile fronthaul, cloud computing, Internet-of-Things (IoT), or the like). The network zones and associated services may be provided using a distance-constrained fiber and wavelength switching fabric design comprised of various network devices and using associated controllers, which may be configured to support service provisioning functions, service testing functions, wavelength switching functions, and so forth.

Near-real-time and real-time communications

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.

Infrastructure resource states

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.
