Abstract
Systems, methods, and machine-readable media are disclosed for switching a media streaming session between a plurality of networks. In one embodiment, a method of switching networks in a media streaming session can comprise detecting a plurality of networks available for communication of streaming data. The plurality of networks can include a first network providing a first streaming session and a second network. A determination can be made as to whether to switch the first streaming session from the first network. Determining to switch the first streaming session from the first network to the second network can be based on detecting a loss of the first network, detecting a lower cost alternative to the first network, etc. In response to determining to switch the first streaming session from the first network, the first streaming session can be switched from the first network to the second network.
