UDR-6G
Unified Data Repository with Distributed Multi-Cloud Ledger
A distributed database engine providing ACID guarantees and geo-replicated subscriber and policy data across multi-vendor hybrid cloud environments.
Technical Explanation
The Unified Data Repository stores structured data for UDM, PCF, and NEF. In 6G, UDR-6G employs distributed consensus (Raft/Paxos) and immutable cryptographic audit logging across heterogeneous public clouds (AWS, Azure, GCP) and on-premise telecom datacenters, ensuring that subscriber profile updates are replicated across global regions in milliseconds with zero split-brain risk.
Key Functions
- Geo-replicated distributed multi-cloud database with sub-millisecond read latency
- Strict ACID transaction guarantees during high-concurrency mobility roaming surges
- Immutable cryptographic audit trails tracking every administrative configuration change
- Transparent sharding and partitioning scaling to hundreds of millions of concurrent records
- Native post-quantum database column encryption securing sensitive subscriber attributes
