Scale video delivery and monitor network traffic by using eCDNs with Microsoft Stream (Classic)

Playback of videos from Microsoft Stream (Classic) and "External app or device" live events (formerly known as "External Encoder" productions) use adaptive bitrate streaming (ABR) delivered as a unicast stream. This means that every viewer is getting their own video stream from the internet. For live events or videos sent out to large portions of your organization, there could be a significant amount of network and internet bandwidth consumed by viewers.

Organizations may want to understand and reduce this network traffic for live events and popular videos. If so, Microsoft Stream (Classic) can be enabled to integrate with trusted Microsoft partners that offer enterprise content delivery network (eCDN) solutions that include self-managing delivery technologies, real-time monitoring, and in-depth network analytics. These eCDN platforms enable organizations to monitor, scale, and optimize the distribution of video streams (and sometimes other content types) across your enterprise network.

Acquire and set up your eCDN solution outside of Stream (Classic)

Get expert help with monitoring and scaling video delivery by teaming up with trusted Microsoft eCDN partners.

Before you can enable an eCDN solution to be used with Microsoft Stream, you must purchase and set up that eCDN solution outside and separate from Microsoft Stream. To ensure that the solution will meet your needs, some partners provide free trials of their content delivery and network analytics technologies.

Several eCDN solutions are pre-integrated and can be enabled for use with Microsoft Stream. See information from the providers below.

    • Search for any video in your organization to validate with.
    • If your eCDN provider is set up correctly, you'll see a "Success" message on the verify setup tool.
    • If you aren't set up correctly, you'll see a "Failure" message. Copy the event message to share with your provider for troubleshooting.

After you configure Microsoft Stream (Classic) for an eCDN solution, any video or live event that is played in Stream (Classic) will take advantage of that solution automatically.


The amsglob0cdnstream12.azureedge.net endpoint needs to be reachable for users in your organization in order to use any of the above eCDN solutions with Microsoft Stream (Classic) or "External encoder" events from Yammer/Microsoft Teams.

Configure "Microsoft Teams" production type events through Microsoft Teams and Yammer for your eCDN solution

If you plan to create Teams live events through Microsoft Teams or Yammer, you'll need to configure your eCDN provider to be integrated with Microsoft Teams as well.

Get to video analytics reports for your eCDN solution

As noted above, some eCDN solutions also provide analytics reports that give deeper information about playback sessions, viewers, and quality of service. If your provider gave you an analytics report URL template to configure when you set up the provider in the Stream (Classic) admin panel, then owners of videos or events can easily get to the analytics report for a specific video or event.

Owners of videos will see an Analytics tab directly under the video. On this tab, there will be a link for owners to access the analytics report for this specific video in the eCDN provider's system.

If you're a Stream (Classic) admin, you can also elevate your access to see the Analytics tab and get to the eCDN analytics report link, even if you aren't an owner of the live event or video.

  1. As a Stream (Classic) admin, go to the video player page

  2. Click Settings Settings icon.

  3. Click View in admin mode

  4. Click the Analytics tab

Troubleshooting issues

You should make sure that your eCDN solution is set up correctly in your network and that you've properly configured Microsoft Stream (Classic) to enable the provider per their instructions and specific configuration strings. If you're still having issues, some of the tactics below might help.

Verify setup tool

If you are having issues with your eCDN solution, you can always come back and run the Verify setup tool. The eCDN provider event messages shown for your test video can give you and your eCDN provider more information on what's not working.

  • Go to Settings Settings icon. > Admin Settings > eCDN provider > Verify setup

Disable eCDN for a specific session via URL query string

To determine if an issue you're seeing is with the eCDN solution or with Stream, you can easily disable the eCDN solution for a specific playback session via query string.

  • If your playback URL already has ? in it, then add &disableSDN=true.

  • If your playback URL doesn't have a ? in it then add ?disableSDN=true.


View eCDN info in browser console

If your eCDN solution provider supports it, they may print debug information during initialization of playback through their solution. This extra info may be helpful in determining what is going wrong. You can enable extra console debug messages via the query string.

  • If your playback URL already has ? in it then add &isSDNDebug=true.

  • If your playback URL doesn't have a ? in it then add ?isSDNDebug=true.


Press F12 on your browser and switch to the Console tab to see all the information printed during loading of the page with the isSDNDebug=true query string set on the playback URL.
