Abstract
A method is provided in one example embodiment and includes generating a bandwidth estimation for an adaptive bitrate (ABR) client; evaluating a current state of a buffer of the ABR client; and determining an encoding rate to be used for the ABR client based, at least, on the bandwidth estimation and the current state of the buffer. A fetch interval for the ABR client increases as the buffer becomes more full, while not reaching a level at which the ABR client is consuming data at a same rate at which it is downloading the data.
