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.}, publisher = {USENIX Association Berkeley, CA, USA}, url = {http://approjects.co.za/?big=en-us/research/publication/qosaas-quality-service-service/}, pages = {6-6}, edition = {Hot-ICE'11 Proceedings of the 11th USENIX conference on Hot topics in management of internet, cloud, and enterprise networks and services, Boston, MA}, }
