#### Test Machine Setup
|Setup Checklist| Value/Explanation
|--------|-------------------------------|
-|Number of machines used| 2
-|Virtual Machines/physical devices| 2
-|Windows OS version | Windows 10 (21H2) and Windows 11 (21H2)
-|RAM | 8 GB
-|Disk size | 127 GB
-|Network | Connected to same network, one that is representative of the corporate network.
-|Pause Windows Updates | This controls the test environment so no other content is made available during the test, and potentially altering the outcome of the test. If there are problems and no peering happens, use 'Get-DeliveryOptimizationStatus' on the first machine to return a real-time list of the connected peers.
-|Ensure all Store apps are up to date | This will help prevent any new, unexpected updates to download during testing.
-|Delivery Optimization 'Download Mode' Policy | 2 (Group)(set on each machine)
-|Delivery Optimization 'GroupID' Policy | Set the *same* 'GUID' on each test machine. A GUID is a required value, which can be generated using PowerShell, ‘[[guid]::NewGuid().](https://blogs.technet.microsoft.com/heyscriptingguy/2013/07/25/powertip-create-a-new-guid-by-using-powershell/)’.
-|**Required on Windows 11 devices only** set Delivery Optimization 'Restrict Peer Selection' policy | 0-NAT (set on each machine). The default behavior in Windows 11 is set to '2-Local Peer Discovery'. For testing purposes, this needs to be scoped to the NAT.

## Peer sourcing observations for all machines in the test group
-As mentioned, the distributed nature of the Delivery Optimization technology is obvious when you rerun 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.

## Conclusion
-Using Delivery Optimization can help make a big impact in customer environments to optimize bandwidth. The peer-to-peer technology offers many configurations, designed to be flexible for any organization. Delivery Optimization uses a distributed cache, across different sources, to ensure the most optimal download experience while limiting the resources used on each device.
