- Act as a route collector
- Establish iBGP peering sessions with routers, route servers, or route collectors within operator networks
- Act as a route collector
The operator starts the iBGP peering session from the Microsoft Connected Cache side using the Azure management portal and then starts the session with the Microsoft Connected Cache node from the router.
In the example configuration below:
- The operator ASN is 65100
- The ASN of the Microsoft Connected Cache cache node is 65100 and the IP address is 192.168.8.99

Delivery Optimization uses locally cached updates to deliver contact via peers. The more content available in the cache, the more likely that peering can be used. In cases where devices have enough local storage and you'd like to cache more content. Likewise, if you have limited storage and would prefer to cache less, use the following settings to adjust the Delivery Optimization cache to suit your scenario:
- [Max Cache Size](#max-cache-size) and [Absolute Max Cache Size](#absolute-max-cache-size) control the amount of space the Delivery Optimization cache can use.
- [Max Cache Age](#max-cache-age) controls the retention period for each update in the cache.

#### Policies to prioritize the use of peer-to-peer and cache server sources
When Delivery Optimization client is configured to use peers and Microsoft Connected Cache (MCC), to achieve the best possible content delivery experience, the client connects to both 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. There are four settings that allow you to prioritize peer-to-peer or MCC sources by delaying the immediate fallback to HTTP source, which is the default behavior.

Download mode dictates which download sources clients are allowed to use when downloading Windows updates in addition to Windows Update servers. The following table shows the available download mode options and what they do. Other technical details for these policies are available in [Policy CSP - Delivery Optimization](/windows/client-management/mdm/policy-csp-deliveryoptimization).
| Download mode option | Functionality when set |
| Download mode option | Functionality when configured |
| --- | --- |
| HTTP Only (0) | This setting disables peer-to-peer caching but still allows Delivery Optimization to download content over HTTP from the download's original source or a Microsoft Connected Cache server. This mode uses additional metadata provided by the Delivery Optimization cloud services for a peerless reliable and efficient download experience. |
| LAN (**1 - Default**) | This default operating mode for Delivery Optimization enables peer sharing on the same network. The Delivery Optimization cloud service finds other clients that connect to the Internet using the same public IP as the target client. These clients then try to connect to other peers on the same network by using their private subnet IP.|
| 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. |
| Internet (3) | Enable Internet peer sources for Delivery Optimization. |
| Simple (99) | Simple mode disables the use of Delivery Optimization cloud services completely (for offline environments). Delivery Optimization switches to this mode automatically when the Delivery Optimization cloud services are unavailable, unreachable, or when the content file size is less than 10 MB. In this mode, Delivery Optimization provides a reliable download experience over HTTP from the download's original source or a Microsoft Connected Cache server, with no peer-to-peer caching. |
| Bypass (100) | Starting in Windows 11, this option is deprecated. Don't set **Download mode** to '100' (Bypass), which can cause some content to fail to download. If you want to disable peer-to-peer functionality, set DownloadMode to (0). If your device doesn't have internet access, set Download Mode to (99). When you set Bypass (100), the download bypasses Delivery Optimization and uses BITS instead. You don't need to set this option if you're using Configuration Manager. |

### Max Cache Age
### Max cache age
MDM Setting: **DOMaxCacheAge**
In environments configured for Delivery Optimization, you might want to set an expiration on cached updates and Windows application installation files. If so, this setting defines the maximum number of seconds each file can be held in the Delivery Optimization cache on each Windows 10 client device. Alternatively, organizations might choose to set this value to "0" which means "unlimited" to avoid peers redownloading content. When "Unlimited" value is set, Delivery Optimization holds the files in the cache longer and cleans up the cache as needed (for example when the cache size exceeded the maximum space allowed). **The default value is 259,200 seconds (three days)**.

# What's new in Delivery Optimization
This article contains information about what's new in Delivery Optimization, a peer-to-peer distribution method in Windows 10 and Windows 11.
## Microsoft Connected Cache (early preview)
Microsoft Connected Cache (MCC) is a software-only caching solution that delivers Microsoft content within Enterprise networks. MCC can be deployed to as many bare-metal servers or VMs as needed, and is managed from a cloud portal. Cache nodes are created in the cloud portal and are configured by applying the client policy using management tools such as Intune.

## New in Delivery Optimization for Windows
### General
[Check out](https://aka.ms/do-fix) the new Delivery Optimization Troubleshooter. This tool provides a device health check to verify the device is set up properly to use Delivery Optimization. To scope the output more specifically, use one of the two switches:
- -p2p: Provides output specific to P2P settings, efficiency, and errors.
- -mcc: Provides output specific to MCC settings and verifies the client can access the cache server.
### Windows 11 22H2
- New setting: Customize vpn detection by choosing custom keywords. Now, you don't have to rely on Delivery Optimization keywords to detect your Vpn. By using the new VpnKeywords configuration you can add keywords for Delivery Optimization to use when detecting a Vpn when in use. You can find this configuration **[VPN Keywords](waas-delivery-optimization-reference.md#vpn-keywords)** in Group Policy or MDM under **DOVpnKeywords**.
