This talk outlines the emerging and the future of Quality of Service in IP networks. It discusses the end-to-end technology/service evolution in an increasingly broadband, converged and seamless environment. It focuses on services, simulation models, network approximations, traffic marking, policing, shaping and scheduling, recourse reservation problems, applicability of the well known techniques like IntServ, DiffServ, RSVP, NSIS in end-to-end Quality of Service negotiation and renegotiation.

The technology evolution is outlined in many layers but mostly on IP. IPv4 and IPv6 change partially the way of QoS management. User-centric and ubiquitous services and access are not usually considered in the literature. Dynamic user requirements are not satisfied.

In this context, the end-to-end areas of research & global dynamics are outlined to inspire our collective focus and energy, and to serve the increasingly mobile users, machines, and virtual societies of the future.
