Delivery Optimization is a cloud management solution. Centrally optimized cache. Internet access is required on the client machine. Each device contributes a little to the other devices in the network to get the content. Helps reduce internet access to retrieve content and use local resources to retrieve content. Hybrid downloads will eventually become the cloud or the closest peer or SCCM distribution point.
Chunk and hash content. Saves metadata from peers. Peace level distribution / companion. When peers are detected, the PC will try to download updates from those systems.
After discovering what the machine needs to download. The device needs to know WU / WSUS and what needs to be downloaded.
Use a DO service other than the MS site to request additional sources on your network.The service needs to see where the client is coming from and provide the data
- Client A checks for updates
- WU returns updated information
- Client A then asks WU for the download source
- Source: WU Content Server, other clients on the network
- Client A requests a specific small piece of the update file from the WU and clients on the network that already have its content.
- Client A checks the hash of each update file and discards the inconsistent hash
- Client A checks the hash of the entire file before installing
What do you need to offer: Run O365 with Windows Update, Upgrades, Drivers, Office Click, WSfB, and applications can include packages with very large files.
If the Express Update installation is enabled, you can use Delivery Optimization in combination with standalone Windows Update, Windows Server Update Services (WSUS), Windows Update for Business, or System Center Configuration Manager.
Where are the files stored? C: Windows DeliveryOptimization
Can I change the cache drive: Yes!
Content cache time: Content that is stored until it expires, or that is cached for 24-72 hours by default. (Can be increased using GP) / 20% maximum HDD space occupancy
How to clear from cache Very popular content remains, and if it is not very popular, it will be cleared when space is low. (Management by GP)
Over 76% of the content came from peer devices rather than the internet.
The following download modes are available for optimizing Windows Update delivery:
0 = invalid
1 = Only peers with the same NAT (default value for ENT or EDU gets 10)
2 = Local network / private peering (PCs in the same domain by default)
3 = Internet Peering
A minimum of 4GB of RAM and more than 32GB of free space.
By default, the device Not uploaded while using battery.. To enable uploads when using batteries, you must enable this policy and set a battery value at which uploads will be paused.
Get-DeliveryOptimizationStatus
Get-DeliveryOptimizationPerfSnap
Get-DeliveryOptimizationPerfSnapThisMonth
Returns data similar to Get-DeliveryOptimizationPerfSnap, but limited to the current calendar month.
For delivery-optimized metadata:
- * .dl.delivery.mp.microsoft.com
- * .emdl.ws.microsoft.com
Clean up the DO cache using the Disk Cleanup utility.
You can use the Local Group Policy Editor to define delivery optimizations.
- Tap the Windows key, type gpedit.msc, and press Enter.
- Using the tree hierarchy on the left[コンピューターの構成]>[管理用テンプレート]>[Windowsコンポーネント]>[配信の最適化]Go to.
Some policies are listed under Delivery Optimization. The main one is the download mode, which determines if delivery optimization is enabled and how it is used.
The download mode can be set to one of the following values:
- 0: WSUS only.
- 1: Optimization of delivery behind the same NAT only. (Default for Enterprise and Education editions of Windows 10)
- 2: Private group only: Same Active Directory site or same domain.
- 3: Delivery optimization uses LAN and internet peers. (Default for Pro and Home editions of Windows 10)
- 99: Simple download mode. Delivery Optimization uses HTTP only and does not connect to the Delivery Optimization cloud service.
- 100: Bypass mode: No delivery optimization is used and BITS is used instead.
The following policies are also provided. Please note that various delivery optimization settings will change. If you turn off this feature, you do not need to configure them.
- Absolute maximum cache size (in GB)– DeliveryOptimization Specifies the maximum size of the cache in gigabytes.
- Group ID: Must be set as a GUID. Used to create a single group for local network peering of branches that are on different domains or not on the same LAN.
- Maximum cache elapsed time (in seconds): The default value is 3 days. Specifies the maximum amount of time, in seconds, that a file is kept in the Delivery Optimization cache.
- Maximum cache size (percentage): The default value is 20%. Defines the maximum cache size used by Delivery Optimization as a percentage of the available disk size.
- Maximum upload bandwidth (KB / sec): The default value is unlimited (0). This value specifies the maximum upload bandwidth for the Delivery Optimization service.
- Maximum download bandwidth (KB / sec): The default value is unlimited (0). This value specifies the maximum download bandwidth used by the service.
- Maximum download bandwidth (percentage): Default value is unlimited (0): Value specifies the maximum download bandwidth as a percentage.
- Minimum background QoS (KB / sec): The default value is 500KB / sec. Specifies the maximum service quality for downloads in kilobytes / second.
- Change cache drive: Specifies the custom drive that Delivery Optimization uses for caching.
- Maximum monthly upload data (in GB): The default value is set to 200 gigabytes. Specifies the maximum total number of bytes that Delivery Optimization can upload to Internet peers, in gigabytes.
You can also use the registry to control functionality.
- Tap the Windows key, type regedit, and press Enter.
- Check the UAC prompt.
The main key is HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows CurrentVersion DeliveryOptimization Config.
Check if the setting DODownloadMode is listed below it. If not,[構成]Right click and[新規]>[Dword（32ビット）値]Select and name it DODownloadMode.
The key accepts the same download mode values listed in Group Policy above (0= Off, 1= On but local network only, 2= On, local network private peering only, 3= On local networks and the internet 99= Simply download mode, 100= Bypass mode).
SCCM integrated DO:
Does delivery optimization work on WSUS? Yes internet connection required
Which port does Delivery Optimization use? For peer-to-peer traffic, use 7680 or 3544 for client service communication and port 80/443.
Note: By default, in Windows 10 Enterprise and Education editions, delivery optimization allows peer-to-peer sharing only on your organization’s own network, but you can configure it differently in Group Policy and MDM.
Note: The peer cache, branch cache, and DO all work independently.
Peer cache: You can create reports using SCCM
Branch cache: so far no custom reports from any tool
Implementation: Data can be collected from Windows Analytics
If you are already using SCCM + peer cache + branch cache on Windows 10 Ent, DO is enabled by default. In this case, if the SCCM client state can be scanned against SUP, download the content from DP or peer. If your machine scans against SUP and you can’t download content from DP or DP, in this case run the download from the MS site or SCCMDP.
