 ## Overview
 
-Delivery Optimization is a powerful and useful tool to help enterprises manage bandwidth usage for downloading Microsoft content. It's a solution designed to be used in large-scale environments with large numbers of devices, various content sizes, etc. Delivery Optimization is native to Win10+ and provides default configuration to get the most out of the typical customer environment. It is used to deliver many different types of content, so Microsoft customers enjoy the best possible download experience for their environment. There are three components to Delivery Optimization, 1) HTTP downloader, 2) Peer-to-peer (P2P) cloud technology, and 3) Microsoft Connected Cache. One of the most powerful advantages of using Delivery Optimization is the ability to fine-tune settings that empower users to dial in Microsoft content delivery to meet the needs of specific environments.

 Several elements that influence overall peering, using Delivery Optimization. The most common, impactful environment factors should be considered.
 
 * **The number of files in the cache and** **the** **number of devices have a big effect on overall peering.** There's a set number of files available for peering at a time, from each client, so the peering device may not be serving a particular file.
-* **File size** **and** **internet connection** **reliability matter.** There's a Delivery Optimization setting to determine the minimum file size to use P2P. In addition, internet connection must be open and reliable enough to let the Delivery Optimization client make cloud service API calls and download metadata files prior to starting a content file download

-As mentioned, the distributed nature of the Delivery Optimization technology is obvious when you re-run the ‘Get-DeliveryOptimizationStatus’ cmdlet on each of the test machines. For each, there's a new value populated for the ‘BytesToLanPeers’ field. This demonstrates that as more peers become available, the requests to download bytes are distributed across the peering group and act as the source for the peering content. Each peer plays a role in servicing the other.
