Tencent Cloud provides the bandwidth cap feature for playback domain name, which is disabled by default. You can set a cap threshold for the downstream bandwidth in the domain name acceleration region. If the peak bandwidth reaches the threshold within a statistical cycle, a 404 error will be returned for all LVB requests. You can enable/disable the bandwidth cap based on the actual usage of the domain name.

Prerequisites

• You have logged in to the LVB Console.
• You have added a playback domain name.
