2 NSSF Features

This section provides the list of added or updated features that are compatible with NSSF Release 23.4.x.

Release 23.4.0

• LCI and OCI Headers: In the 5G architecture, frequent network overload due to substantial data exchanges between producer and consumer Network Functions (NFs) necessitates precise load balancing to prevent failures. Quick communication of an overloaded state from producer NFs to consumer NFs is crucial for proactive corrective actions. LCI and OCI Headers emerge as key tools, enabling real-time insights into NSSF resources and facilitating efficient traffic management. These headers equip consumer NFs with critical load and overload information, optimizing traffic distribution and proactive measures during overload scenarios, ensuring a stable, high-performing 5G Core Network, even under heavy loads. For more information, see "LCI and OCI Headers" section in Oracle Communications Cloud Native Core, Network slice Selection Function User Guide.
• Server Header in NSSF: The Network Slice Selection Function (NSSF) in 5G handles security aspects and manages requests from various network functions (NFs) and entities via HTTP. When errors occur, consumer NFs need to identify the issue's source for troubleshooting. NSSF integrates a feature using Server Headers in its responses, providing essential details about the error's origin and type. This enhancement in NSSF responses improves error handling for better troubleshooting and corrective actions by the consumer NFs.
