Overlay networks and distributed services are currently favorite approaches to add new functionality to the network. Often, these approaches strongly rely on accurate information about the current state of nodes and network to increase performance, efficiency and user experience. Based on previous work, we show how UNISONO provides this information while hiding the complexity of the measurement task. UNISONO is a generic framework for host-based distributed network measurements. In this paper, we present UNISONO as a way towards consolidated measurement for the creation of overlays as well as for service placement. We give an overview of the UNISONO concept as well as security considerations of such a service and show how distributed services benefit from its usage.
