‘Cloud Native Network Functions (CNF) - within 5G Core Service Based Architecture (SBA)’ - presented at Layer123 World Congress in London, UK on December 6^th. 2022

I. Cloud Native Network Functions (CNF) - Within 5G Core Service Based Architecture (SBA)

5G Standalone (SA) Brings Service Based Architecture (SBA)

• Benefits of 5G Service Based Architecture
• Shift from Reference Point Architecture – Nodes and VM Silos to Software Functional Decomposition of VNFs

II. VNFs and CNFs

• VNFs
• VNFs and CNFs = Containers and Microservices
• CNFs operate as Microservices
• Microservices Demand Service Mesh
• Microservice Interactions generate massive numbers of Control Plane transactions
• CNFs in Telco Cloud Operations
• Verizon Cloud Platform integrates VNFs and CNFs
• OpenShift now Supports Scalable, Distributed, Real Time VNFs and Microservices

III. CSP Roadmap to Leverage CNFs, work with Hyperscaler Cloud Providers (HCPs) and Interoperate with Cloud Native Apps
