Background Intelligent Transfer Service (BITS)
Detailed description
The latest version of Background Intelligent Transfer Service (BITS), BITS 2.0, includes dramatically improved bandwidth efficiency. This means that, when Automatic Updates connects to the Windows Update site or a server running Windows Update Services, it has to transfer less data, and can transfers the data faster. This minimizes the impact Automatic Updates might have on your Internet connection or corporate network. BITS improvements include the following:
? BITS 2.0 can be configured to download updates during a specified time, such as periods of less network use.
? BITS 2.0 can be configured to use only a specific portion of available network bandwidth.
? BITS 2.0 is optimized to download only the portions of files that have changed. For example if only one byte changed in an updated 1 megabyte (MB) file, BITS will transfer only a few bytes instead of transferring the entire 1 MB file.
? BITS 2.0 can recover from network failures. BITS can resume a file transfer if a network fails or a connection is lost during download. It will not restart the download, but instead will start from where it stopped.
