<span lang="en">Quality of service has become one of the most important factors among Internet service providers. The implementation of appropriate QoS policies is essential in order to maintain customer loyalty and fulfill regulators' requirements. ITU-T recommendation E.802 provides a framework for the identification of QoS criteria relevant to users and ISPs. This Recommendation also provides guidelines to derive measurable QoS parameters from identified criteria. This article presents a QoS management model and implementation methodology for ISPs. We ground our investigation on the E.802 framework, which ISPs may face when implementing ITU-T Recommendation G.1000. The proposed methodology is meaningful for users, vendors, and network operators. Furthermore, its conformance with the ITU-T standard makes it suitable and deployment-ready for both regulators and providers.</span>

<span lang="en">This paper proposes the deployment of a network software platform for experimentation called LabQoS that will allow the scientific community to establish scientific experiments relating to measure the performance of applications and services on the Internet and other network environments. Previous experiences have already deployed measurement systems, but they don't incorporate the concept of control of the scenario to enable the performing of experiments. This LabQoS capacity makes it an innovative platform unique in its approach. A module called Test Environment Builder has been designed in order to monitor the operating parameters, and to propose adaptation strategies to handle the scenario control variables. We define an experimental data model that identifies the entities to be considered in the management of the platform. Assessment mechanisms are proposed to study the dynamic sensitivity of the control variables with respect to the parameters. LabQoS is based on QoSMETER architecture that addresses technological aspects such as user management, deployment tools, data collection, reporting, security, etc.</span>
