Systems and methods described herein provide a Specialized-Operator enabled with admission control functionalities and Custom Resource Definition (CRD) plugins responsible for improving the reliability of the CNF Lifecycle Management operations for deploying containerized workloads on any heterogeneous cloud platform or in multi-cluster environments. According to one implementation, a computing device includes a sensor Network Function Virtualization (NFV)-extension and an actuator NFV-extension. The sensor NFV-extension obtains, from a Container Infrastructure Service Manager (CISM), an event signal that indicates a deficiency with a customer Containerized Network Function (CNF) deployment; detects a current state for the CNF deployment; determines an intent for the CNF deployment; identifies, based on the intent, a desired state for the CNF deployment; and selects, from a group of available actuator NFV-extensions, the actuator NFV-extension corresponding to the desired state. The actuator NFV-extension may be configured to initiate remediation of the CNF deployment to the desired state.

In some implementations, a first core network device may transmit, to a second core network device may, a host responsiveness monitoring request, wherein the host responsiveness monitoring request indicates at least one host responsiveness parameter associated with a host device that is to be monitored, and wherein the at least one host responsiveness parameter is associated with the host device adapting a transmission rate associated with one or more service data flows in response to receiving one or more packets marked with an explicit congestion notification. The first core network device may receive, from the second host device, a host responsiveness monitoring report indicating data associated with the at least one host responsiveness parameter associated with the host device.

One or more computing devices, systems, and/or methods for upgrading sites of a communication network are provided. Operational information of network functions within a communication network are tracked within a data repository. An upgrade ruleset is defined for identifying sites within a communication network to upgrade. The operational information, the upgrade ruleset, and model rules generated by a model for a set of candidate sites are processed to generate a positive list of sites to upgrade and a negative list of sites to not upgrade. The negative list of sites and criteria used to determine that the negative list of sites are not being upgraded are provided such as to a user. An upgrade process is performed to upgrade the sites within the positive list of sites.

In some implementations, a first device may receive, from a second device, network function (NF) configuration information indicating that an NF instance is to be provisioned to support a combination of network slices. The NF configuration information may include first network slice information regarding the first network slice and second network slice information regarding the second network slice. The first device may obtain, from a data structure, first slice configuration information associated with the NF instance supporting the first network slice and second slice configuration information associated with the NF instance supporting the second network slice. The first device may generate configuration parameters to provision the NF instance to support the combination of network slices and provide the configuration parameters to cause the NF instance to be provisioned to support the combination of network slices.

A device may receive application information of an application to be deployed in a cloud computing environment. The application information may include requirement information including information defining a compute requirement of the application, a storage requirement of the application, and a network connectivity requirement of the application, and first capability information identifying requested capabilities of the first set of devices. The device may receive second capability information identifying actual capabilities of the second set of devices. The device may compare the first capability information and the second capability information to determine a measure of similarity between the first capability information and the second capability information. The device may generate deployment information for deploying the application on a device, of the second set of devices, based on the measure of similarity.

Systems and methods for cloud topology management during deployment of virtual applications

Systems and methods described herein provide deployment optimization service. A network device in a network receives an order for virtual network function (VNF) deployments at network edge locations. The network device maps a radio access network (RAN) topology for the network edge locations. The network device identifies time windows to perform the VNF deployments, based on the order, historical transport and RAN utilization data, and the RAN topology. The network device selects an optimal time window to perform the VNF deployments based on stored policy rules and pushes software images for the VNF deployments to an image repository in a geographical region near the network edge locations. The network device analyzes, for the optimal time window, real-time network data for a pre-emptive condition. The network device pre-empts the VNF deployments when a pre-emptive condition is identified and initiates the VNF deployments when no pre-emptive condition is identified.

A network device may receive, for an emergency call, a session initiation protocol (SIP) invite that includes a registered address of a user device that initiated the emergency call, and may determine whether the user device is associated with a private network based on the SIP invite. The network device may extract the registered address of the user device from the SIP invite and based on the user device being associated with the private network, and may provide the registered address to another network device. The other network device may determine a registered geographic location of the user device, based on the registered address, and may provide the registered geographic location to a public safety answering point associated with the emergency call.

Systems and methods implement closed loop analytics feedback for a transport network. A network device, such as a Network Data Analytics Function (NWDAF), receives, from a commissioning network function, an analytic information request for analytic event information and sends, to the commissioning network function, an analytic report that is responsive to the analytic information request wherein the analytic report includes a unique analytic report identifier. The network device receives, from the commissioning network function, a feedback event message that includes the analytic report identifier and a change description for a network parameter change influenced by the analytic report.

The device may generate testing configurations, for testing the proposed VNFs, based on the interface dependencies, and may determine that a set of the proposed VNFs are validated based on testing the proposed VNFs with the testing configurations. The device may derive dependency constraints for the set of the proposed VNFs based on the information identifying the existing VNFs, and may select a new VNF that satisfies the dependency constraints, based on the set of the proposed VNFs.
