URL Blacklisting Solution Components
The URL Blacklisting solution uses the deep-packet inspection capabilities of ECS for URL/URI extraction.
ECS functionality is managed by the following components:
Session Controller (SessCtrl) : The SessCtrl runs on the primary SPC/SMC and is responsible for managing
ECS and URL Blacklisting services.
Session Manager (SessMgr) : A single SessMgr treats ECS charging and URL Blacklisting that is applicable to
common subscriber sessions.
Apart from ECS, the URL Blacklisting solution uses the following components:
Content Filtering Subsystem in ECS
Web Element Manager (WEM)
