More options available that control the impact Delivery Optimization has on your network include the following:
|
||||
|
||||
- [Maximum Download Bandwidth](#maximum-download-bandwidth) and [Percentage of Maximum Download Bandwidth](#percentage-of-maximum-download-bandwidth) control the download bandwidth used by Delivery Optimization.
|
||||
- [Max Upload Bandwidth](#max-upload-bandwidth) controls the Delivery Optimization upload bandwidth usage.
|
||||
- [Monthly Upload Data Cap](#monthly-upload-data-cap) controls the amount of data a client can upload to peers each month.
|
||||
- [Maximum background download bandwidth (in KB/s)](#maximum-background-download-bandwidth-in-kbs) to control the amount of bandwidth for downloading in the background in KB/s.
|
||||
- [Maximum foreground download bandwidth (in KB/s)](#maximum-foreground-download-bandwidth-in-kbs) to control the amount of bandwidth for downloading in the foreground in KB/s.
|
||||
- | [Maximum foreground download bandwidth (percentage)](#maximum-foreground-download-bandwidth) to control the amount of bandwidth for downloading in the foreground based on percentage.
|
||||
| [Maximum background download bandwidth (percentage)](#maximum-background-download-bandwidth) to control the amount of bandwidth for downloading in the background based on percentage.
|
||||
- [Minimum Background QoS](#minimum-background-qos) lets administrators guarantee a minimum download speed for Windows updates. This setting adjusts the amount of data downloaded directly from HTTP sources, rather than other peers in the network.
|
||||
- [Maximum Foreground Download Bandwidth](#maximum-foreground-download-bandwidth) specifies the **maximum foreground download bandwidth** that Delivery Optimization uses, across all concurrent download activities, as a percentage of available download bandwidth.
|
||||
- [Maximum Background Download Bandwidth](#maximum-background-download-bandwidth) specifies the **maximum background download bandwidth** that Delivery Optimization uses, across all concurrent download activities, as a percentage of available download bandwidth.

| Group (2) | When group mode is set, the group is automatically selected based on the device's Active Directory Domain Services (AD DS) site (Windows 10, version 1607) or the domain the device is authenticated to (Windows 10, version 1511). In group mode, peering occurs across internal subnets, between devices that belong to the same group, including devices in remote offices. You can use GroupID option to create your own custom group independently of domains and AD DS sites. Starting with Windows 10, version 1803, you can use the GroupIDSource parameter to take advantage of other method to create groups dynamically. Group download mode is the recommended option for most organizations looking to achieve the best bandwidth optimization with Delivery Optimization. |

The default download mode setting is **1**; this means all devices breaking out to the internet using the same public IP will be considered as a single peer group. To prevent peer-to-peer activity across your WAN, you should set the download mode to **2**. If you have already defined Active Directory sites per hub or branch office, then you don't need to do anything else since those will be used by default as the source for creation of Group IDs. If you're not using Active Directory sites, you should set a different source for Groups by using the [DOGroupIDSource](waas-delivery-optimization-reference.md#select-the-source-of-group-ids) options or the [DORestrictPeerSelectionBy] (waas-delivery-optimization-reference.md#select-a-method-to-restrict-peer-selection) policy to restrict the activity to the subnet.

Windows updates, upgrades, and applications can contain packages with large files. Downloading and distributing updates can consume quite a bit of network resources on the devices receiving them. You can use Delivery Optimization to reduce bandwidth consumption by sharing the work of downloading these packages among multiple devices in your deployment. Delivery Optimization is an HTTP downloader with a cloud-managed solution that allows clients to download those packages from alternate sources (such as other peers on the network and/or a caching server) in addition to the traditional internet-based servers (referred to as 'HTTP sources' throughout Delivery Optimization documents). You can use Delivery Optimization with [Windows Update](../update/how-windows-update-works.md), Windows Server Update Services (WSUS), [Microsoft Intune/Windows Update for Business](/mem/intune/configuration/delivery-optimization-windows), or [Microsoft Configuration Manager](/mem/configmgr/sum/deploy-use/optimize-windows-10-update-delivery#windows-delivery-optimization) (when installation of Express Updates is enabled).

To use either the peer-to-peer functionality or the Microsoft Connected Cache features, devices must have access to the Internet and Delivery Optimization cloud services. When Delivery Optimization is configured to use peers and Microsoft Connected Cache (MCC), to achieve the best possible content delivery experience, the client will connect to MCC and peers in parallel. If the desired content can't be obtained from MCC or peers, Delivery Optimization will automatically fallback to the HTTP source to get the requested content.

Windows updates, upgrades, and applications can contain packages with large files. Downloading and distributing updates can consume quite a bit of network resources on the devices receiving them. Delivery Optimization is a reliable HTTP downloader with a cloud-managed solution that allows Windows devices to download those packages from alternate sources if desired (such as other devices on the network and/or a dedicated cache server) in addition to the traditional internet-based servers (referred to as 'HTTP sources' throughout Delivery Optimization documents).

When Delivery Optimization is configured to use peers and Microsoft Connected Cache (MCC), to achieve the best possible content delivery experience, the client will connect to MCC and peers in parallel. If the desired content can't be obtained from MCC or peers, Delivery Optimization will seamlessly fall back to the HTTP source to get the requested content.
