Binary Delta Compression (BDC) technology helps reduce the download size of software update packages for Windows operating systems. BDC works by compressing and downloading only the differences between old files and new files, thereby creating smaller software update packages that require less time and network bandwidth to install. Files downloaded from later versions of Microsoft Windows Update also support the use of the Background Intelligent Transfer Service (BITS), which asynchronously transfers update files, preserves the responsiveness of other network applications, and automatically resumes file transfers after restarts or network disconnects. In addition, update installations that use the latest version of the Microsoft Software Update Services (SUS) client no longer require Microsoft Internet Information Services (IIS) server but can download updates from any server that supports HTTP 1.1, thereby reducing server traffic. Together, BDC and BITS can help streamline the process for downloading critical and security updates.
