Bandwidth Optimization

Microsoft has released a guide for IT administrators focused on optimizing Windows deployments and reducing bandwidth usage through Windows Delivery Optimization configured via Microsoft Intune. Delivery Optimization uses a peer-to-peer sharing system, allowing devices to download content from each other instead of solely from Microsoft servers, which helps reduce internet strain for organizations with many Windows PCs. Administrators can create specific peer groups based on network topology and control bandwidth usage for downloads, with options to set different limits for business and off-hours. Microsoft also introduced Connected Cache, which stores frequently accessed content locally to further minimize bandwidth consumption. A statistic shared by Microsoft indicates that using Delivery Optimization can significantly reduce internet traffic, as a 1 GB update for 10,000 devices could otherwise generate 10 TB of internet traffic. The guide recommends starting with a small seeder ring of devices to populate peer caches before wider deployment. Microsoft provides specific policy settings for Delivery Optimization, including default and recommended values for settings such as download mode, peer selection, cache size, minimum file size for caching, cache age, and monthly upload data cap. Proper configuration of Delivery Optimization is suggested to benefit organizations managing large numbers of devices.
