Abstract: This disclosure relates to a communication network within which devices participating in a communication session dynamically switch between sending media streams to a participating network device through one of multiple communication channel options. For instance, when establishing a communication session (e.g., a video conference), a sending network device establishes two potential communication channels with a receiving network device participating in the communication session. The sending network device determines which of the two potential communication channels is best suited for providing a media stream related to the communication session (e.g., an audio and/or video media stream), and assigns that communication channel as an active communication channel over which the sending network device provides the media stream to the receiving network device.
