How to orchestrate the distributed edge servers?• Service lifecycle management,
• Service scalability and availability, and resilient,
• Service security,
• Service maintenance (Zero-touch maintenance/Automation)

Control/User Plane Separation (CUPS) in 5G● User Plane Function (UPF) handles all of the user-plane functions
performed by SGW-U and PGW-U in 4G EPC.
● Control Plane Functions such as Authentication Server Function (AUSF), User Data Management (UDM), Policy and Charging Function (PCF) and Session Management Function (SMF).
21
How does CUPS helps in reducing network latency?Deploying the control plane functions
1. co-located with the user plane functions○ (i.e., in the same data center)
2. And user-plane functions both in a distributed fashion, across multiple
locations.
3. in a centralized location and deploy the user-plane functions in multiple
locations
