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 to WEM in a preconfigured path.
E-mail notification: Provides alerts and notification to the administrator for alarms.
ECS Storage System
The local and remote external storage servers are part of ECS Storage System in the ECS solution architecture.
The L-ESS and R-ESS are 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, Report Engine at CDP, and the R-ESS. The R-ESS consolidates the processed EDR/UDR files into a database
for report generation through UDR Report Generator or EDR Report Generator at CDP.

When Content Filtering is deployed in conjunction with ECS, the operator has an option of collocating the Central
Decision Point (CF-CDP) with an ESS thereby eliminating the requirement of the CF-CDP to fetch a copy of the CF-
EDRs from each system running ECS and Content Filtering service. The database generated on an ESS by processing
EDR/UDR records is a superset of the database required by a CF-CDP.

RADIUS Server and Policy Manager
The function of the RADIUS Server/Policy Manager in the Content Filtering solution is to provide per-subscriber
Content Filtering provisioning information when a subscriber‘s session is established. It can also issue a Change-of-
Authorization (CoA) to update an in-progress session to modify the Content Filtering policy for a subscriber.

The following are the basic functions provided by a RADIUS Server/Policy Manager in the Content Filtering solution:
Support for the in/out ACL attributes to direct traffic through ECS for processing of subscriber traffic
Support for ECS rulebase VSA to select the ECS rulebase to be applied to filtered traffic
Support for Content Filtering Policy identifier VSA to select the content filtering policy within the selected
rulebase for a subscriber
Support exporting a subscriber provisioning record based on MSID to the customer service interface (Customer
Care Interface) so that operator‘s customer care executive can see the provisioned content filtering policy for a
subscriber
