Abstract: Techniques are described for managing streaming video profile selections of downstream client devices for a network device. The network device receives multicast network communications for a first video streaming profile of a plurality of video streaming profiles, for a video content item. The network device is subscribed to multicast communications from an upstream network device, for a video stream corresponding to the first video streaming profile. Embodiments determine network state information at the network device that specifies at least a measure of upstream network error. Upon determining that the network state information satisfies one or more criteria, data communications from the network device to a downstream client device for the video stream corresponding to the first video streaming profile are throttled.

Abstract: Techniques for managing receiving, at a network receiver device, from a video streaming solution, segments for each of a plurality of video streams over one or more multicast channels, where the network receiver device is configured to cache the segments for consumption by one or more client devices. A first network congestion condition is satisfied at the network receiver device. In response to detecting the first network congestion condition is satisfied, a first one of the plurality of video streams having a lower priority is selected, relative to a second one of the plurality of video streams. Segments for the first video stream are requested using an alternate channel. Embodiments unsubscribe from a first one of the multicast channels for the selected first video stream.
