Bandwidth Cap Configuration

Last updated: 2022-05-20 10:42:04

    CSS allows you to set a bandwidth cap for your playback domain. In the acceleration region of your domain, if the peak downstream bandwidth in a reference period hits the cap you set, a 403 error will be returned to playback requests. This feature is disabled by default.
