<span lang="en">Deployment of quality-of-service (QoS) policies is becoming one of the biggest challenges for today's Internet Service Providers (ISPs). Nowadays, QoS does not only address specific technical standard metrics; it must be concern about other aspects such as user's final perception or regulations mandatory compliments instead. Although some efforts are being made on studying and analysing this new QoS scope, there are not still many advances on defining methodologies to deploy it on real network sceneries. UIT-T Rec. G-1000 makes an approachon this issue and provides a meaningful framework to users, service providers and regulators. Nevertheless, UIT-T G.1000 does not go an step further and remains at the "theorical stage". Our research group NQaS (Networking Quality and Security) is carrying out different initiatives focus on solving this new QoS dimension. This paper presents some of the on-going research areas of NQaS on the way to find an appropiate methodology to apply a global QoS policy in an ISP on the basis of the UIT-T G.1000 framework.</span>
