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 provision of quality of service (QoS) in IP‐based networks, namely QoS IP networks, has led to new demands for routing methods, protocols and algorithms. It is widely recognized that such QoS routing should take into account multiple criteria. In this case, contemporary approaches in multiple‐criteria analysis should be taken into account, and they differ essentially from classical routing approaches. An alternative to classical routing algorithms that are not quite able to respond to all the challenges of QoS IP networks, especially from the perspective of Future Internet, is to change routing approaches and algorithms to provide for consistent multiple‐criteria routing approaches. This is also related to the understanding of the concept of hierarchy in routing, discussed in the paper. The paper recalls the concept of objective ranking, shows its appropriateness for consistent multiple‐criteria routing and presents a conceptual framework for routing based on objective ranking, including hierarchy of routing optimization and multiple routing tables. The paper has a conceptual nature, with the purpose of analyzing possible approaches to multiple‐criteria routing that might be useful if not today, then in the engineering of future networks. However, a network engineering interpretation of the concepts proposed here is also presented.

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

In this paper, the EuQoS Consortium offers its first architecture release in order to provide an initial view on how end to end QoS is provided over multiple and heterogeneous networks. The EuQoS end to end Architecture has two views; a network deployment view across a number of autonomous systems (AS) domains and a software view within an AS. It was funded on a division of the end to end QoS paradigm along a vertical axisService, Control and Transport plane -and an horizontal axis -network division between the various technology especially Core and Access networks. The solution is based on the concept of end to end path build, used and managed by three processes: Provisioning, Invocation and Operating Maintenance (0AM).
