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

QoS: the problemQoS: the problem

The debate on QoS in the Internet has been running for more than 10 years, but only the “easy” solutions are implemented.

Overprovisioning (only a solution for the backbone)

Exploiting the capabilities of the lower layers (MPLS)

? Priorities (DiffServ)

? Explicit signalling (RSVP)

? 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

ObjectivesObjectives

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 Architecture with GRE tunnel and BGP 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
