Advanced Quality of Service (aqos): An overlay network mechanism to improve service delivery

摘要

This paper proposes a mechanism which allows extending IMS service delivery on the Internet using overlay networks. Dubbed Advanced Quality of Service (AQoS), this solution aims at dynamically providing alternate high-bandwidth routes on the Internet using overlay network measurements to improve connection QoS. The estimation of the achievable QoS in the overlay network makes it possible to adapt IMS service delivery.
