Subscriber Database Server (SDS) provides the central provisioning of the Full-Address Based Resolution (FABR) data. The SDS, which is deployed geo-redundantly at a Primary and Disaster recovery site, connects with the Query Server and the Data Processor Site Operation Administration and Maintenance (DP SOAM) servers at each Diameter Signaling Router (DSR) site or a standalone DP site to replicate and recover provisioned data to the associated components.
SDS provides the following functionality:
- SDS Database – Stores subscriber data needed by the FABR application
- GUI-based provisioning
- Control the Diameter Internet Engineering Task Force (IETF) specification called Diameter Routing Message Priority (DRMP) to establish relative message priorities
- Enhanced Subscriber Table add functionality
- Support SOAP over HTTP and XML over TCP as provisioning interfaces
- SQL Interface – At query server for query only
- CSV and/or XML-formatted export and import of database contents
- Real Time replication to:
- Local standby server at Primary site
- Local query server at Primary site
- Each server at Disaster Recovery site
- Each DP SOAM and DP at up to 32 sites
- DP - DB Processor – A server that has a replica of the SDS database and is available for query by FABR applications
- Automatic scheduled NPA Split processing
- Provisioning Measurements and KPIs
- Alarms, Events and Logs for all interfaces
- DB Audit - Replication audit within replicas and Active SDS, and remote audit between SDS and HLR Router
- Query server
- Backup and Restore of SDS database components
- Disaster Recovery SDS – Geo-diverse site
- Automated Performance Data Export (APDE)
- Manage and associate routing destinations for routing entities that represent Subscriber identities
- Monitor exceptions
- Subscriber identity grouping
- Blacklist support
- Address resolution – Full address, as well as prefix address support
