Control Plane Network Functions
The CP-related NFs that comprise the Ultra Cloud Core are based on a common architecture that is designed around the following tenants:
Cloud-scale—Fully virtualized for simplicity, speed, and flexibility.
Automation and orchestration—Optimized operations, service creation, and infrastructure.
Security—Multiple layers of security across the deployment stack from the infrastructure through the NF applications.
API exposure—Open and extensive for greater visibility, control, and service enablement.
Access agnostic—Support for heterogeneous network types (for example 5G, 4G, 3G, Wi-Fi, and so on).
These control plane NFs are each designed as containerized applications (for example microservices) for deployment through the Subscriber Microservices Infrastructure (SMI).
The SMI defines the common application layers for functional aspects of the NF such as life-cycle management (LCM), operations and management (OAM), and packaging.
