QoSaaS is a new framework that provides QoS information portals for enterprises running real-time applications. By aggregating measurements from both end clients and application servers, QoSaaS derives the quality information of individual system components and enables system operators to discover and localize quality problems; end-users to be hinted with expected experience; and the applications to make informed adaptations. Using a large-scale commercial VoIP system as a target application, we report preliminary experiences of developing such service. We also discuss remaining challenges and outline potential directions to address them.
