EuQoS Approach
Support the evolution of the Internet
into a multi-service network
Take a pragmatic approach
SME
Sell QoS as a new source of
revenue.
Define business models

QoS: the problem
State of the Art
The debate on QoS in the Internet has
been running for more than 10 years, but
only the “easy” solutions are
implemented.
3 Overprovisioning (only a solution for
the backbone)
3 Exploiting the capabilities of the
lower layers (MPLS)
? Priorities (DiffServ)
? Explicit signalling (RSVP)
EuQoS Approach
Support the evolution of the Internet
into a multi-service network
Take a pragmatic approach
Sell QoS as a new source of
revenue.
Define business models
? NSIS
Why ?
• QoS may be demanded from the
network, or applications may adapt to
what is available
• Researchers like to look for new
solutions
• Manufacturers like to sell new products

Objectives

To foster the interoperability of end-to-end QoS solutions for the end
user, across heterogeneous research, scientific and industrial network
domains.

To promote the creation of new business models to enable the
deployment of QoS applications by the Internet community.

To promote the use and the awareness of QoS applications and
technologies, involving technical people, clinical communities and
aerospace, educational, corporate and SME end users.

To develop a roadmap and strategic guidance for the development of
end-to-end QoS technologies in Europe, promoting training education
and technology transfer to the industry in end-to-end QoS technologies
and QoS aware applications.

To address the standardization of end-to-end QoS issues in European
and International bodies, especially the IETF, and contribute to
strengthening the European research community and industry with the
wider adoption of European technology.

Architecture with GRE tunnel and
BGP
• In the first phase, a mesh of GRE tunnels are setup between all
partners
• All partners maintain BGP sessions with each other, so that one partner
can act as endpoint or as transit network

Trials
• Two measurement tools are used (1 commercial, 1 OS)
• Probes are located in relevant points
• The trials are carried out in diferent scopes:
• Local
• Site to site
• E2e
