UDSF-6G
Unstructured Data Storage Function with In-Memory Key-Value
An ultra-fast, distributed in-memory key-value cache allowing 6G network functions to remain completely stateless for instant failover and auto-scaling.
Technical Explanation
To achieve true cloud-native elasticity, 6G control plane network functions must be completely stateless: if an AMF or SMF container crashes, another instance must immediately take over the session without the user noticing. UDSF-6G provides a distributed, microsecond-latency in-memory data store (built on Redis/Dragonfly clusters) where transient session contexts, timers, and TCP states are cached and synchronized across edge clusters.
Key Functions
- Microsecond-latency in-memory key-value storage for transient session states
- Enabling 100% stateless network function architectures for instantaneous auto-scaling
- Instantaneous session state recovery upon unexpected container or node crashes
- Dynamic memory eviction and TTL expiration policies preventing memory leaks
- Geo-distributed replication keeping edge session caches warm prior to user handovers
