Abstract: Embodiments generate and provide connection quality data for networks based on past performance of those networks. Network experience data and corresponding device context are received from a first set of mobile devices. The received data is processed to generate the connection quality data, which is distributed to a second set of mobile devices for use in selecting a network and establishing a connection. Feedback describing performance of the selected network is received and applied to adjust the previously generated connection quality data. In some embodiments, the connection quality data represents voice over Internet Protocol (VoIP) call quality.

Abstract: Embodiments select networks for connection based on application-specific quality scores. A request is received from an application for a network connection. Connection quality data for nearby networks is accessed. The connection quality data is derived from crowdsourced data. The connection quality data is adjusted based on a device context to produce an application-specific quality score for each of the networks. One or more of the networks are selected for connection based on the application-specific quality scores. In some embodiments, a single network connection endpoint is provided to the application to abstract connection management details from the application.
