  Delivery Optimization GP
  This file describes the Delivery Optimization GP settings
  
    
      Delivery Optimization
      Download Mode
      Specifies the download method that Delivery Optimization can use in downloads of Windows Updates, Apps and App updates.
      
The following list shows the supported values:

0 = HTTP only, no peering.
      
1 = HTTP blended with peering behind the same NAT.

2 = HTTP blended with peering across a private group. Peering occurs on devices in the same Active Directory Site (if exist) or the same domain by default. When this option is selected, peering will cross NATs. To create a custom group use Group ID in combination with Mode 2.
      
3 = HTTP blended with Internet Peering. 

99 = Simple download mode with no peering. Delivery Optimization downloads using HTTP only and does not attempt to contact the Delivery Optimization cloud services.
      
100 = Bypass mode. Do not use Delivery Optimization and use BITS instead.
      HTTP only (0)
      LAN (1)
      Group (2)
      Internet (3)
      Simple (99)
      Bypass (100)
      Group ID
      Group ID must be set as a GUID. This Policy specifies an arbitrary group ID that the device belongs to.
      
Use this if you need to create a single group for Local Network Peering for branches that are on different domains or are not on the same LAN.
      
Note: this is a best effort optimization and should not be relied on for an authentication of identity.
      Max Upload Bandwidth (in KB/s)
      Specifies the maximum upload bandwidth that Delivery Optimization uses across all concurrent upload activities in KB/second.
      
The default value 0 (zero) permits an unlimited use in which uploads are dynamically optimized for minimal usage of upload bandwidth.
      Max Cache Size (percentage)
      Specifies the maximum cache size that Delivery Optimization uses as a percentage of available disk size (1-100).
      Absolute Max Cache Size (in GB)
      Specifies the maximum size in GB of Delivery Optimization cache.
      
This policy overrides the DOMaxCacheSize policy.
      
The value 0 (zero) means "unlimited" cache; Delivery Optimization will clear the cache when the device runs low on disk space.
      Max Cache Age (in seconds)
      Specifies the maximum time in seconds that each file is held in the Delivery Optimization cache after downloading successfully.
      
The value 0 (zero) means "unlimited"; Delivery Optimization will hold the files in the cache longer and make the files available for uploads to other devices, as long as the cache size has not exceeded.
      Monthly Upload Data Cap (in GB)
      Specifies the maximum total bytes in GB that Delivery Optimization is allowed to upload to Internet peers in each calendar month. 
      
The value 0 (zero) means "unlimited"; No monthly upload limit is applied if 0 is set.
      Minimum Background QoS (in KB/s)
      Specifies the minimum download QoS (Quality of Service or speed) for background downloads in KiloBytes/second. 
      
This policy affects the blending of peer and HTTP sources. Delivery Optimization complements the download from HTTP source to achieve the specified minimum QoS value.
      Modify Cache Drive
      Specifies the drive Delivery Optimization shall use for its cache. 
      
By default, %SystemDrive% is used to store the cache. The drive location can be specified using environment variables, drive letter or using a full path.
      Maximum Download Bandwidth (in KB/s)
      Specifies the maximum download bandwidth in KiloBytes/second that the device can use across all concurrent download activities using Delivery Optimization. 
      
The default value 0 (zero) means that Delivery Optimization dynamically adjusts to use the available bandwidth for downloads.
      Maximum Download Bandwidth (percentage)
      Specifies the maximum download bandwidth that Delivery Optimization uses across all concurrent download activities as a percentage of available download bandwidth. 
      
The default value 0 (zero) means that Delivery Optimization dynamically adjusts to use the available bandwidth for downloads.

This policy is deprecated and will be removed in the next release. Use Maximum Foreground Download Bandwidth (percentage) or Maximum Background Download Bandwidth (percentage) instead.
      Maximum Background Download Bandwidth (percentage)
      Specifies the maximum background download bandwidth that Delivery Optimization uses across all concurrent download activities as a percentage of available download bandwidth. 
      
The default value 0 (zero) means that Delivery Optimization dynamically adjusts to use the available bandwidth for background downloads.
      Maximum Foreground Download Bandwidth (percentage)
      Specifies the maximum foreground download bandwidth that Delivery Optimization uses across all concurrent download activities as a percentage of available download bandwidth.
      
The default value 0 (zero) means that Delivery Optimization dynamically adjusts to use the available bandwidth for foreground downloads.
      Minimum Peer Caching Content File Size (in MB)
      Specifies the minimum content file size in MB enabled to use Peer Caching. 
      
Recommended values: 1 MB to 100000 MB.
      Enable Peer Caching while the device connects via VPN
      Specify "true" to allow the device to participate in Peer Caching while connected via VPN to the domain network.
      
This means the device can download from or upload to other domain network devices, either on VPN or on the corporate domain network.
      Minimum RAM capacity (inclusive) required to enable use of Peer Caching (in GB)
      Specifies the minimum RAM size in GB required to use Peer Caching. 
      
For example if the minimum set is 1 GB, then devices with 1 GB or higher available RAM will be allowed to use Peer caching. 
      
Recommended values: 1 GB to 4 GB.
      Minimum disk size allowed to use Peer Caching (in GB)
      Specifies the required minimum disk size (capacity in GB) for the device to use Peer Caching. The cloud service set default value will be used. 
      
Recommended values: 64 GB to 256 GB. 
      
Note: If the DOModifyCacheDrive policy is set, the disk size check will apply to the new working directory specified by this policy.
      Allow uploads while the device is on battery while under set Battery level (percentage)
      Specify any value between 1 and 100 (in percentage) to allow the device to upload data to LAN and Group peers while on DC power (Battery). 
      
The recommended value to set if you allow uploads on battery is 40 (for 40%). The device can download from peers while on battery regardless of this policy. 
      
The value 0 means "not-limited"; The cloud service set default value will be used.
      [Reserved for future use] Cache Server Hostname
      [Reserved for future use]
      Select the source of Group IDs
      Set this policy to restrict peer selection to a specific source. 
      
Options available are: 

1 = AD Site.

2 = Authenticated domain SID.

3 = DHCP Option ID.

4 = DNS Suffix. 

When set, the Group ID will be assigned automatically from the selected source. If you set this policy, the GroupID policy will be ignored. 
      
The options set in this policy only apply to Group (2) download mode. If Group (2) isn't set as Download mode, this policy will be ignored. 

For option 3 - DHCP Option ID, the client will query DHCP Option ID 234 and use the returned GUID value as the Group ID.
      Unset (0)
      AD Site (1)
      Authenticated domain SID (2)
      DHCP Option ID (3)
      DNS Suffix (4)
      Delay background download from http (in secs)
      This policy allows you to delay the use of an HTTP source in a background download that is allowed to use P2P.
      
After the max delay has reached, the download will resume using HTTP, either downloading the entire payload or complementing the bytes that could not be downloaded from Peers.
      
Note that a download that is waiting for peer sources, will appear to be stuck for the end user.
      
The recommended value is 1 hour (3600).
      Delay Foreground download from http (in secs)
      This policy allows you to delay the use of an HTTP source in a foreground (interactive) download that is allowed to use P2P.
      
After the max delay has reached, the download will resume using HTTP, either downloading the entire payload or complementing the bytes that could not be downloaded from Peers.
      
Note that a download that is waiting for peer sources, will appear to be stuck for the end user.
      
The recommended value is 1 minute (60).
      Select a method to restrict Peer Selection
      Set this policy to restrict peer selection via selected option. 
      
Options available are: 
1 = Subnet mask (more options will be added in a future release). 
      
Option 1 (Subnet mask) applies to both Download Mode LAN (1) and Group (2).
      None
      Subnet
      Set Business Hours to Limit Background Download Bandwidth
      Specifies the maximum background download bandwidth that Delivery Optimization uses during and outside business hours across all concurrent download activities as a percentage of available download bandwidth.
      Set Business Hours to Limit Foreground Download Bandwidth
      Specifies the maximum foreground download bandwidth that Delivery Optimization uses during and outside business hours across all concurrent download activities as a percentage of available download bandwidth.
