Quality of service management for ISP: A model and implementation methodology based on ITU-T Rec. E.802 framework

Quality of service (QoS) has become one of the most important factors among Internet service providers (ISPs). 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 the users and the ISPs. This recommendation also provides guidelines to derive measurable QoS parameters from identified criteria. This paper presents a QoS management model and implementation methodology for ISPs. We ground our investigation on Rec. E.802 framework which the ISPs may face when implementing ITU-T Rec. G.1000. The proposed methodology is meaningful for the users, the vendors, and the network operators. And its conformance to ITU-T standard makes it suitable and deploy-ready for both regulators and providers.
