The EuQoS (End-to-End QoS over Heterogeneous Networks) IST Integrated European Project aimed to define a Next Generation Network architecture that builds, uses and manages end-to-end QoS across different administrative domains and heterogeneous networks (UMTS, xDSL, Ethernet, WiFi, Satellite and IP/ MPLS). The EuQoS architecture preserves the openness and the decentralized decision model of the actual Internet, runs on off-the-shelf hardware and network equipment, and allows end users to request various services without changing the Application Signaling protocol, while meeting regulators' and users' Net Neutrality requirements. This paper presents the key elements of the EuQoS architecture and describes the main results obtained in field trials performed on a fully-functional EuQoS system prototype developed over a pan-European testbed. Furthermore, the paper discusses the main strengths of the system and the issues related to its actually deployment on a large scale, from both technical and market points of view.

In this paper, we present the framework to provision end-to-end QoS in heterogeneous multi-domain networks that was implemented in EuQoS system and tested in Pan-European research network.
The EuQoS system is a complete QoS system, scalable to large dimensions and addressing QoS at all relevant layers, which has been developed within the framework of the IST-EuQoS project. Its design has been aided by a considerable amount of modeling and simulation work, aimed at testing the various QoS mechanisms devised and their interaction. This paper describes the modeling and simulation work done in the framework of the project. We describe the three simulation models which have been developed, based on the different timescales at which the QoS mechanisms have effect. Furthermore, as a sample case of performance evaluation, involving different simulators, we describe the performance evaluation of the EuQoS signaling subsystem
