3. 3 Heidelberg, 14 - 15 October 1998 QUTE’98 Workshop Terje Jensen, Telenor Applying the EQoS Framework Background user provider (sub-)provider QoS_u QoS_s QoS_L user Recursive QoS relationships: QoS_u = g(QoS_L, QoS_s) QoS parameters

4. 4 Heidelberg, 14 - 15 October 1998 QUTE’98 Workshop Terje Jensen, Telenor Applying the EQoS Framework Motivation Multi-provider Regulatory considerations User requirements Services Network configurations......... to establish and maintain appropriate QoS levels

5. 5 Heidelberg, 14 - 15 October 1998 QUTE’98 Workshop Terje Jensen, Telenor Applying the EQoS Framework Interconnection configurations - Example Interconnection = physical/logical linking of facilities/actors providing network/service allowing users to interact/access end-user access transport R SCP/SDP R end-user access = end-interface agreement = provider-to-provider interface agreement = end-to-end agreement

6. 6 Heidelberg, 14 - 15 October 1998 QUTE’98 Workshop Terje Jensen, Telenor Applying the EQoS Framework Business interface model Business model - comprised of actors, various roles these actors may play and the contractual relationships between these roles user Service provider transport/ connectivity provider = Interface agreement (contractual relationship)

8. 8 Heidelberg, 14 - 15 October 1998 QUTE’98 Workshop Terje Jensen, Telenor Applying the EQoS Framework Aims of interconnection agreements i) “Throughput” ii) “Protection” Provider AProvider B Agreement principles: best effort level compulsory level guaranteed level

9. 9 Heidelberg, 14 - 15 October 1998 QUTE’98 Workshop Terje Jensen, Telenor Applying the EQoS Framework Why harmonised? fast, accurate, automatic (rapid service deployment/offer, multiple actors involved,.....) Why generic structure? service complexity network/system configurations number of actors involved regulatory/user requirements.... Interconnection agreements

10. 10 Heidelberg, 14 - 15 October 1998 QUTE’98 Workshop Terje Jensen, Telenor Applying the EQoS Framework Interconnection agreements - generic structure interfaceQoS parameters traffic patterns measurement schemes QoS thresholds reaction patterns “Entity A” “Entity B”

11. 11 Heidelberg, 14 - 15 October 1998 QUTE’98 Workshop Terje Jensen, Telenor Applying the EQoS Framework Interconnection configurations end-user access transport R SCP/SDP R end-user access = end-user interface related = provider-provider interface related

12. 12 Heidelberg, 14 - 15 October 1998 QUTE’98 Workshop Terje Jensen, Telenor Applying the EQoS Framework Interconnection configurations vertically separated domains (different functionality levels) horizontally separated domains (similar functionality levels) Interconnection = physical/logical linking of facilities/actors providing network/service allowing users to interact/access domain A domain B domain A

13. 13 Heidelberg, 14 - 15 October 1998 QUTE’98 Workshop Terje Jensen, Telenor Applying the EQoS Framework Example - Intelligent Networks

14. 14 Heidelberg, 14 - 15 October 1998 QUTE’98 Workshop Terje Jensen, Telenor Applying the EQoS Framework Example - Internet R R = interconnection agreement

15. 15 Heidelberg, 14 - 15 October 1998 QUTE’98 Workshop Terje Jensen, Telenor Applying the EQoS Framework Exchange of QoS/interconnection information Information collecting/ processing Service provider User Options: no data exchange bilateral data exchange best practice data exchange aggregated data exchange full data exchange Rationale: regulatory (ONP/other directives) service quality degradation localisation....
