XR-074: Loss of Connectivity to Xbox and Partner Services *

  • Article

Version 1.2, 04/01/2024

Titles must gracefully handle errors with Xbox and partner services connectivity. Titles must honor the retry policies set by Xbox when attempting to retry a request to the Xbox service after a failure has occurred. Titles must appropriately manage messaging the user when services are unavailable. If a partner service is not available, the game must not indicate that there is an issue with the Xbox network. Titles must not crash or hang if network services are slowed or intermittently available.

More Information

Titles should react to the performance of their own network operations and/or use Windows.Xbox.Networking network quality APIs to determine current network conditions. They should also degrade gracefully by transferring less data, choosing appropriate user roles, or leveraging cloud services.

Handling Issues With Non Xbox Services

Titles encountering issues with partner services such as non-transient timeouts, network API errors, or missing service configuration that impacts the user experience should alert the user to the specific feature or service that is unavailable. Titles should fail gracefully to a safe state while the user troubleshoots, or to a state in which the user can manually retry.

An example of a user-friendly message is:

"Sorry, non-Microsoft service is not currently available. Please try again later. For more information, contact non-Microsoft support contact information."

Handling Issues With Xbox Services

Some functionality might become unavailable if connectivity to an Xbox service is lost. In such instances, titles should use clear, user-friendly messaging to communicate this to users.

If a service is unavailable, titles are permitted to retry their request, but they can do so only within the parameters allowed by Xbox. For more information about service resiliency for Xbox console titles, including required HTTP retry and back-off logic, as well as user-interaction guidance for individual services, see Service Interruption Resiliency for Titles

Requiring Xbox Connectivity

When developing for Xbox consoles, titles that require connectivity to the Internet—or Xbox, in particular—for the majority of their functionality might want to include the Boolean flag RequireXboxLive in their AppX manifest. This will block the title from initiating on the Xbox console when Xbox is unavailable and it will suspend, and subsequently terminate, the title if connectivity is lost.

074-05 Constant Low Bandwidth

Tools Needed: xbstress.exe from the GDK/XDK.

Configuration: Network simulation is controlled by the command-line stress tool xbstress.exe. This tool configures various console stressors, including network simulation. For networking purposes xbstress.exe controls a specialized driver on the Xbox device, which drops packets, injects latency, and limits throughput. xbstress.exe has three pre-configured simulation profiles that allow you to easily simulate important networking scenarios: minimum, average, and excellent. The minimum profile maps to this XR.

Test Steps

  1. Using XBStress' minimum profile, throttle connectivity to Xbox device's minimum operating requirements.
  2. Perform title-related online actions, including but not limited to:
  • Navigating all menus.
  • Playing an online game session.

Expected Result
Titles must not crash or cause user data loss when user's internet connection drops below 192 Kbps.

Pass Examples

  1. User-friendly message is displayed indicating possible impact to online play due to low bandwidth.
  2. Title does not crash and does not cause a loss of user data.

Fail Examples

  1. Title crashes or causes user data loss.

074-06 Variable Low Bandwidth

Tools Needed: xbstress.exe from the GDK/XDK.

Configuration: Network simulation is controlled by the command-line stress tool xbstress.exe. This tool configures various console stressors, including network simulation. For networking purposes xbstress.exe controls a specialized driver on the Xbox device, which drops packets, injects latency, and limits throughput. xbstress.exe has three pre-configured simulation profiles that allow you to easily simulate important networking scenarios: minimum, average, and excellent. The minimum profile maps to this XR.

Test Steps

  1. Disable all network restrictions in xbstress.
  2. Perform title-related online actions, including but not limited to:
  • Navigating all menus.
  • Playing an online game session.
  1. While performing Step [2], enable xbstress' minimum profile.

Expected Result
Titles must not crash or cause user data loss when user's internet connection drops below 192 Kbps.

Pass Examples

  1. User-friendly message is displayed indicating possible impact to online play due to low bandwidth.
  2. Title does not crash and does not cause a loss of user data.

Fail Examples

  1. Title crashes or causes user data loss.

074-07 Dynamic Connectivity Loss

Tools Needed:

  • xbstress.exe from the GDK/XDK
  • For Windows 10, Fiddler Classic

Configuration:
For Xbox devices, network simulation is controlled by the command-line stress tool xbstress.exe. xbstress.exe allows the user to block a list of domain names and IPs, this test is performed with a provided list of addresses to block non-Microsoft traffic.

Test Steps

  1. Sign in to an Xbox profile.
  2. Launch the title.
  3. Access non-Microsoft online feature.
  4. If testing on Xbox devices, create a broken network channel with xbstress for non-Microsoft traffic using the command:

  2. If testing on Windows 10, use fiddler to emulate downtime.

Expected Result
Title should gracefully handle disconnections to non-Microsoft service.

Pass Examples

  1. Title does not hang or crash upon loss of connectivity to the partner-hosted service.

Fail Examples

  1. Error displayed implies issues with Microsoft service.
  2. Non-descriptive error message is displayed.
  3. Title crashes, becomes unstable, or causes console reboot.

074-08 Pre-Launch Downtime

Tools Needed:

  • xbstress.exe from the GDK/XDK
