The concept of SATO (Service-aware Adaptive Transport overlays) is proposed within a European project (Ambient Networks). It introduces a virtual network, named overlay network, to fit the particular requirements of the Ambient Networks' services, and to achieve service adaptation and service customization. In its first phase, the QoS consideration design relied only on the underlying physical network, depending on some traffic engineering such as the classification of the traffic as well as QoS-routing mechanism etc. However, the QoS-aware service management, especially for the QoS service adaptation within overlay network, has been neglected. In this paper, we propose a solution, which enable QoS information into the overlay service management, so as to provide a QoS aware service overlay network (QSON). Within such QSON, service components are organized into different subnets, while, the service belonging to the same subnet has the similar QoS. With the help of such QoS-aware service subnets, service lookup and selection will be achieved in a way where QoS is integrated into such information retrieval. Using a P2P-based service location system, the service routing will be QoS-aware, and is proved to be scalable and have good performance.
