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
