August 2, 2000AAAARCH Meeting, IETF Pittsburgh 5 TODO Policy-based accounting draft Policies for configuration of accounting and QoS auditing –Configuration of meters and measurement infrastructure –Exchange of accounting polices for inter-domain accounting and accounting indications More examples ! AAA concepts for DiffServ –SLA as information base for accounting and QoS auditing policies –Bandwidth broker vs. AAA server roles –Accounting for network services –QoS auditing Terminology (session, service, etc.) User-to-flow mapping Session ID –maybe associated to meter rules

Thank You !
