Bridging the standardization Gap to provide QoS in current NGN architectures

Abstract

The provisioning of quality of service is mandatory to ensure the success of next-generation networks in an all-IP environment. In this article we describe all the problems we faced during the design, implementation and validation of the EuQoS system (which has been demonstrated as a viable solution to provide end-to-end QoS over heterogeneous networks) and some recommendations that, according to our experience, should be taken into account to success in the specification of an NGN architecture able to improve the quality of experience (QoE) of Internet users, following net neutrality requirements. In particular, we highlight the importance of defining transparent and usable end-user interfaces and the impact of specific network equipment implementations on the deployment of NGN.
