Receives the Unknown URLs file (Vendor Format Unknown Database File (VFUNKDB)) from MCRDBS.
Master Content Rating Database Server (MCRDBS)
The Category-based Content Filtering solution provides a Master Content Rating Database Server to convert the
VFMDB to SFMDB. It handles both full and incremental updates and processes them on a configured schedule.
This server is also responsible for distribution of SFMDB data files to WEM servers in the customer support
infrastructure on a configured interval.
The server is responsible for following functionality as the MCRDBS solution:
Database fetching: Pulls VFMDB files from third-party Content Rating Server to MCRDBS.
Database conversion: Converts VFMDB files to SFMDB files. It also handles the incremented and unknown
database files.
Database poller: Provides the converted SFMDB database files for WEM in a preconfigured path.
E-mail notification: Provides alerts and notification to the administrator for alarms.
ECS Storage System
The local external storage server is a part of ECS Storage System in the ECS solution architecture.
The L-ESS is a storage application running on redundant highly available servers that collect and process EDRs and
UDRs from which billing events and reports are generated. Either the system pushes the EDR/UDR files to the L-ESS,
or the L-ESS fetches them from the system and processes them into formats suitable for billing mediation servers and
inPilot. The L-ESS consolidates the processed EDR/UDR files into a database for report generation through inPilot. The
database generated on an ESS by processing EDR/UDR records is a superset of the database required by inPilot.
Important:
For more information on External Storage Systems, refer to the ESS Installation and Administration
Guide .

Authorization (CoA) to update an in-progress session to modify the Content Filtering policy for a subscriber.
