A cache device may receive a request for a first segment of an adaptive bitrate stream. The request may identify a particular time interval, of the adaptive bitrate stream, to which the first segment corresponds. The request may further identify a first bitrate at which the first segment is encoded. The cache device may determine a network congestion level of a network associated with the adaptive bitrate stream. The cache device may determine, based on the network congestion level, a second bitrate that is different from the first bitrate. The cache device may obtain a second segment of the adaptive bitrate stream. The second segment may be encoded at the second bitrate. The cache device may store the second segment for delivery to a client device.
