Provision of distributed testbed
– Integration of network technologies, applications and services
– topics addressed are: access networks, IPv6, QoS, security, mobility,
interworking & interoperability
Support IST and National research projects for testing their system
– Applications and test equipment provision
– Link to GEANT to test across 5 testbeds in Brussels (BE), Bern (CH),
Heidelberg (G), Sophia-antipolis (FR), Budapest (HU)
Liaison with other IST projects to promote NGN: participation in clusters and
concertation process

Dr. S. Rao
Objectives
The key objective of EuQoS is to research,
develop, integrate, test, validate trial and
demonstrate end-to end QoS technologies to
support advanced QoS aware applications voice, video-conferencing, video streaming,
tele-engineering and medical applications - over
multiple, heterogeneous research, scientific
industrial and national research network
infrastructure testbeds.

QoS Issues Addressed
EuQoS is an intelligent integration of building blocks, including:
• Admission Control mechanisms specific to each access network
technology and for use inter-domain
• Signalling and Service Negotiation between domains, triggered
by Application Level Signalling (eg. SIP-based)
• Monitoring & Measurement to ensure SLAs are being kept, and
to provide input for Traffic Engineering, Admission Control and
Service Negotiation
• Traffic Engineering
• AAA to authenticate and authorise the user (and their QoS
profile), and to collect accounting data for Charging
• Novel interface features such as Control APIs, Signalling APIs,
Extended QoS APIs and Transport related QoS middleware

Summary
EuQoS scope
• EuQoS will strengthen the research
networking in Europe.
- Leveraging research
networking infrastructure
(NRNs)
- Proposing solutions for the
present bottlenecks
(application and access)
• Following the Internet model
(service/network independence),
the openness of the solution is seen
as a main objective of the project
• EuQoS will make the solution
available through technology
transfer to the telecommunications
industry, both to established and
new entrants
Core: NRN, Telcos
Access: Telcos
+ New entrants
Services: Virtually anybody
• The primary focus of the operators is the exploitation of the results of the project into
services which will deliver new value and can be delivered to business and domestic
consumers
