This feature saves bandwidth costs by throttling the response from a web server

  • Internet Information Services 7.0 (IIS7) Media Pack Bit Rate Throttling module has compelling features for media and data delivery. For many scenarios, this feature will reduce bandwidth costs while increasing per-server capacity for concurrent download connections.

    For media files, Bit Rate Throttling implements a dynamic per-file throttling capability to provide intelligent progressive downloading. It automatically detects the encoded bit rate of each file, sending the first few seconds at the highest data rate possible, and then throttling the rest of the file download based on the encoded bit rate. This saves network bandwidth while preserving the fast start-up experience for the end user.

    In addition, the Bit Rate Throttling module provides control over download rates for any file type, not just media files. While eleven media formats are pre-defined in the module, the module is fully extensible. This allows a developer to add support for any media file type, and allows an administrator to easily add support for any data file type.
