Concepts and technologies are disclosed related to allocation of hardware resources for virtual network function (VNF) deployment at sites based on templates. A design template defines hardware resources to allocate for a service, and a deployment policy defines deployment of the virtual network functions (VNFs) associated with the service to the hardware resources. Hardware resources are allocated at one or more sites based on the design template to host VNFs for the service, and VNFs are deployed to the hardware resources based upon the deployment policy.

Allocating hardware resources for virtual network function deployment at sites based on templates

Aspects of the subject disclosure may include, for example, executing an OTT application; and providing an API that enables the OTT application to connect with a native SIP stack of the device, where the OTT application negotiates with a network server for one or more QoS parameters for a communication service provided via the OTT application. Other embodiments are disclosed.

Systems and methods to provide account, billing and QoS SLA for OTT communication applications

Techniques for validating alignment between network element configuration and DNS records associated with a communication network are presented. Alignment management component (AMC) can retrieve respective configuration parameter data items relating to respective configuration parameters associated with respective resource-related identifiers, and respective metadata items associated with the respective resource-related identifiers, from a configuration data store; and retrieve respective DNS records from respective DNS name servers, based on analyzing the respective metadata items associated with respective DNS records. For each resource-related identifier that is supposed to have a corresponding DNS record, based on the result of analyzing the respective configuration parameter data items and respective DNS records, AMC can determine whether the resource-related identifier has a corresponding DNS record stored in the DNS name server indicated by the metadata item. AMC can generate an audit report comprising a missing DNS record data item for each DNS record determined to be missing.

Validation of alignment of wireless and wireline network function configuration with domain name system records

Aspects of the subject disclosure may include, for example, a method in which a processing system creates a network element by consolidating a control plane including a combination of a plurality of 5G control plane functions and a plurality of IMS control plane functions with an associated user plane including a combination of a 5G user plane function (UPF) and one or more IMS user plane functions. The method also includes deploying the network element at a network edge of the service provider network, receiving a request from a user endpoint (UE) device for a network service, and attaching the UE to the network element. The network element is configured to facilitate providing the requested network service. Other embodiments are disclosed.

System and method for deployment of 5G and next-generation core with IMS core for real-time applications

Aspects of the subject disclosure may include, for example, a device in which a processing system defines service attributes for a function of an internet multimedia subsystem (IMS) core; the function is dedicated for providing a service to a user endpoint (UE) device. The processing system facilitates constructing a resource profile of the IMS core that includes the function; registering the function at a network repository function (NRF) associated with the IMS core; discovering the function from the NRF; obtaining a service requirement of the UE; and matching the service requirement with the service attributes in accordance with matching criteria. Other embodiments are disclosed.

System to create and manage IMS functional resource profile groups for alignment with 5G slices

Concepts and technologies are disclosed herein for providing a network virtualization policy management system. An event relating to a service can be detected. A first policy that defines allocation of hardware resources to host the virtual network functions can be obtained, as can a second policy that defines deployment of the virtual network functions to the hardware resources. The hardware resources can be allocated based upon the first policy and the virtual network functions can be deployed to the hardware resources based upon the second policy.

Network virtualization policy management system

A method for bundling network functions as a single microservice in a cloud environment. A service deployment manager may acquire subscriber location information associated with a subscriber or a subscriber profile associated with the subscriber. Moreover, the service deployment manager may utilize the subscriber location information or the subscriber profile to select a cloud location. For example, the cloud location may be based on load, geographical proximity, service profile, etc.

Systems and methods to deploy cloud-native microservices for communication services on scale

Faults are managed in a virtual machine network. Failure of operation of a virtual machine among a plurality of different types of virtual machines operating in the virtual machine network is detected. The virtual machine network operates on network elements connected by transport mechanisms. A cause of the failure of the operation of the virtual machine is determined, and recovery of the virtual machine is initiated based on the determined cause of the failure.

Methods, systems, and computer readable storage devices for managing faults in a virtual machine network

When a virtualized service platform encounters a catastrophic fault, an orchestrator may instantiate new virtual machines instances to deploy additional capacity in other cloud locations to handle failover storms. After the network fault is fixed and service returns to normal condition, these additional VM instances may be removed from the platform and cloud resources may be released. The system may minimize the resource over-provisioning and may continue to support geographical redundancy or dynamic scaling in a large-scale service network.

Geographical redundancy and dynamic scaling for virtual network functions

A method for vNF chaining management includes receiving virtualized network function (vNF) information from a chaining client associated with a particular vNF. A service chaining catalog is updated based on the vNF information and chaining information is transmitted to peering vNFs of the particular vNF. The vNF information can indicate instantiation of a vNF and identify peering vNFs. Updates received from vNFs can be used to update the chaining catalog. Updated vNF information can then be sent to peering vNFs of the vNF which sent the update.
