Single link speed limit

Last updated: 2020-04-22 12:12:17

    COS supports traffic control for file uploads and downloads to guarantee normal network bandwidth for your other applications. You can add the x-cos-traffic-limit parameter in a request for PutObject, PostObject, GetObject, or UploadPart and set a speed limit value. Then, COS will control the network bandwidth for the request accordingly.

    Instructions

    • You can add the x-cos-traffic-limit parameter when requesting Object, PostObject, GetObject, or UploadPart to specify the speed limit value for the request. This parameter can be set in the header, request parameter, or form field (for upload through form).
    • The value of the x-cos-traffic-limit parameter must be a number and the unit is bit/s by default.
    • The speed limit value range is 819200–838860800, i.e, 100 KB/s–100 MB/s. If the range is exceeded, a 400 error will be returned.

    API Use Case
