- question: How does Delivery Optimization determine which content is available for peering?
answer: |
Delivery Optimization uses the cache content on the device to determine what's available for peering. For the upload source device, there's a limited number (4) of slots for cached content that's available for peering at a given time. Delivery Optimization contains logic that rotates the cached content in those slots.
- question: What is the recommended configuration for Delivery Optimization used with Zscaler?
answer: |
The best configuration with Zscaler is to bypass the [hostnames](waas-delivery-optimization-faq.yml#what-hostnames-should-i-allow-through-my-firewall-to-support-delivery-optimization) for Delivery Optimization services and allow that traffic to go directly to the Internet and not through Zscaler.
For communication between clients and the Delivery Optimization cloud service:
• *.do.dsp.mp.microsoft.com
If that's not an option, that try using Group Download mode '2' would be the best next step. For more information on using Group mode, https://learn.microsoft.com/en-us/windows/deployment/do/waas-delivery-optimization-reference#select-the-source-of-group-ids
- question: How do I turn Delivery Optimization off?
answer: |
Delivery Optimization is an HTTP downloader used by a majority of content providers from Microsoft. When a Windows device is configured to use Delivery Optimization peering (on by default), for the content types, in addition to the HTTP downloader capabilities the Delivery Optimization peering service
can be used to optimize bandwidth. If you'd like to prevent the peering capabilities of Delivery Optimization, you can simply change the setting to Download Mode '99', [Simple mode](waas-delivery-optimization-reference.md#download-mode). This will prevent any peering for the downloaded content.
Delivery Optimization will still be used as the HTTP downloader, but any communication to the cloud peering service will be disabled.
- question: Delivery Optimization is using device resources and I can't tell why?
answer: |
Delivery Optimization is used by a majority of content providers from Microsoft. A complete list can be found [here](waas-delivery-optimization.md#types-of-download-content-supported-by-delivery-optimization). Often times customers don't realize the vast application of Delivery Optimization and different apps can be
running in the background. There are different Delivery Optimization [settings](waas-delivery-optimization-reference.md) that can help manage the amount of bandwidth, time of day, etc. Also note that depending on the app, closing the app don't necessarily stop the download.
