Database and Accounting Module
The Accounting Module processes requests/ replies (authentication, authorization, accounting, etc.) coming from the service selection management or a Accounting Server/ Proxy. Currently it is using the Radius protocol but can easily be replaced or expanded by other protocols.
The service selection management communicates through the database module with external databases in order to fetch a user and service profile, make changes to the user profile, etc. In particular it can use an LDAP Client Module to communicate with the Service Management System (SMS) that uses a LDAP directory server. If different databases that already exist have to be expanded, this module can be customized to the used system (e.g. SQL).
