Cisco ASR 5000 Series Product Overview ▄
OL-22938-01
CF-CDP configuration and management
Alarm/trap management
Configures and manages the operator-defined White/Black static rating database (WBLIST) for the network
(WBLIST is maintained in SFMDB format)
Content filtering database management functions:
Performs database processing in the background
Imports full and incremental SFMDB and SFMDB-INC files from the MCRDBS on a configured
schedule
Processes incremental SFMDB-INC updates from MCRDBS maintaining an updated SFMDB file
Merge the operator‘s WBLIST database with the most recent SFMDB creating a SFCMDB
Computes an incremental update to the OPTCMDB-INC suitable for updating the Content Filtering
subsystem that contains a previous version OPTCMDB
Distributes OPTCMDB/OPTCMDB-INC files to CF-CDPs automatically at configured interval
Central Decision Point (CF-CDP) and Report Engine (RE)
The Category-based Content Filtering solution also includes a Central Decision Point (CF-CDP) with Report Engine
that can be integrated in an R-ESS of ECS Storage System. The CF-CDP consists of a geographically redundant server
hosting the CDP application that may be the same as Remote-External Storage Server in ESS.

In the Category-based Content Filtering solution, the CF-CDP performs the following major functions:
Subscriber CF-EDR database processing and management
Optimized Customer Content Rating Master Database distribution
Content Rating Service for Customer-Care Management application
The primary activity of the CF-CDP is to process CF-EDRs into a database that supports report generation by the WEM,
and query processing by the Customer-Care Management application.
and query processing by the Customer-Care Management application.
In addition, the CF-CDP serves as a repository and distribution node for the optimized content rating master database
and incremental updates (OPTCMDB/OPTCMDB-INC). CF-System uses the OPTCMDB to perform the actual Content
Rating Function on subscriber traffic. The OPTCMDB database is also used by an instance of the static and dynamic
rating engines running on the CF-CDP to provide a functional rating service that is leveraged by the Customer-Care
application to display the static rating of a URL and/or corresponding dynamic rating for the URL‘s content.

The CF-CDP server provides updated configuration files to the CF-System with the latest revisions to the static
categorization database. The Content Filtering application also provides a mechanism to properly distinguish between
release versions. The configuration updates are securely transmitted via SFTP over SSH via the out-of-band
management network to a SPIO interface and the local management context of the chassis.

management network to a SPIO interface and the local management context of the chassis.
Updates to the CF-System occurs on requests or configured periodicity. To further reduce the volume of traffic over the
management network, instead of retransmitting the entire SRDB at each update, it is also possible to send small
incremented differential files that include only the additional URLs that were added since the previous update.
