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

Project EQoS Objectives

• 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

EQoS Task 3Title: Definition of IN and Internet interconnect scenariosObjective: Assess the applicability of - and advice improvements to - the common framework for QoSWORK:• 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

EQoS Task 4

Title: Measurement ManagementObjective: 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
