Active SDS Server

The active SDS server on the Primary Provisioning Site accepts input from the Web GUI and from a SOAP and/or XML interface. The active SDS server is responsible for applying all database updates (adds, changes, and deletes) and replicating appropriate updates to the:

• Primary Provisioning Site Standby SDS server
• Primary Provisioning Site Query server
• DR Provisioning Site Active SDS server
• All subtending DP SOAMs at the Signaling Sites

The active SDS server on the Primary Provisioning Site provides a GUI which is used for configuration, user administration, and viewing of alarms and measurements. The active SDS server distributes all successful incoming subscriber provisioning data, independent of source, to all downstream Network Elements (Query server and DP SOAMs on the Signaling Sites) and the DR Provisioning Site.

To ensure that the database levels of the Network Elements are no more recent than the database levels of the SDS servers on the Primary and DR Provisioning Sites, the active SDS Server on the Primary Provisioning Site provisions the active SDS server on the DR Provisioning Site before updating the Signaling Sites (data processing (DP) SOAM and DPs).

Both the active and standby SDS servers share a VIP address. The active SDS server owns the VIP address. If the current standby SDS server becomes active, it acquires the VIP address.
