1. Rationale for the EQoS Survey of Existing Standards and Working Groups Ola Espvik, Telenor R&D on behalf of BT,DT,FI,FT,HT,NL,NT,PT,ST

2. Why All this Talk About QoS?

3. Functional Dependenciesin Multi-Provision Functions provided Functions provided depends on depends on depends on Functions provided Functions provided depends on depends on Functions provided

4. Agreements in Multiprovision provider provider ----------------- user user provider ------------ user provider ------------ user provider ----------- user

5. Functional Layer N+1 Functional Layer N Functional Layer N-1

6. The Agreement! User Provider

7. Quality of Service Service X function X1 function X2 function X3 - - P1, P2,...

8. To Find OUT ! QoS ADMINISTR. FUNCTIONS P1,P2…. SERVICE X function X1 function X2 - - TECHNICAL FUNCTIONS P8, P9….

10. What QoS Framework do we need? • In multi-provision where services are delivered at business interfaces • Acc. to ONP directives e.g. as stated by regulators • All phases of service provision • All kinds of services at various functional levels • All kinds of users/providers - including major network • operators/service providers as well as other parties • All kinds of networks ( logical and physical) • All kinds of technologies • QoS control and maintenance aspects e.g. measurements and RCA

11. Project EQoSObjectives • Define a common framework/definitions for QoS • Verify the framework in IN and Internet scenarios • Define methods for measurement management • for data exchange • Refine the framework/definitions and prepare an MoU

12. EQoS Organisation T2 T2 T3 Definition of IN and Internet Interconnect Scenarios QoS Interface and Common Framework for QoS T4 Measurement Management

13. EQoS Task 2 Title: QoS Interface and Common Framework for QoS • Objective: Establish a Common QoS Framework • in a Multi-Provider Environment • WORK • Investigate int. standard, de facto standards • Requirements to a common framework • A generic QoS User-Provider interface • A generic Common QoS framework • MoU

14. EQoS Task 3 • Title: Definition of IN and Internet interconnect scenarios • Objective: Assess the applicability of - and advice • improvements to - the common framework • for QoS • WORK: • Investigate work being done in other fora • Establish IN and Internet scenarios • Establish business interface models • Outline QoS aspects in interconnect agreements • Approach mapping between interfaces related to: • Exchange of data • Failure detection analyses • Negotiation • Reaction pattern

15. EQoS Task 4 • Title: Measurement Management • Objective: Propose data management models that can be used to • to assess the usefulness of the QoS framework • WORK • Investigate regulatory/competition issues • Bilateral • Common body • Measurement/data collection processes for assessing QoS • Definition of parameters • Evaluation criteria • Common targets • Information modelling
