Access to Xbox services seems fine, in general, but access to a particular service (such as Achievements) is very slow.The user can't access one of the servers that a studio uses to host custom services.The user can't access the Xbox network (also known as Xbox Live), but all other network resources are available.You can simulate such complex network conditions by using the channel feature of xbstress (NDA topic) Authorization required.įor example, you would use channels to simulate conditions such as the following: In addition, test it in situations where a console can reach some of the endpoints that it uses but where other endpoints are unavailable or connection bandwidth is limited. To verify that your network code is robust and ready for certification, test it when it's confronted with complex network conditions. Run a simulation of complex network conditions If you simulate the average profile on two consoles on the same link, their effective peer-to-peer latency would be 50 ms in both directions. To simulate the average profile, we implement an effective latency of 50 ms by injecting a 25-ms delay on inbound and outbound packets. Latency is injected in both directions of the console's network flows. Represents excellent broadband connectivity. Focus on this profile when testing your title's network performance. Titles must be able to support this environment without stopping their response or crashing to fulfill Xbox certification requirements. Represents the minimum operating requirements of Xbox One. Even when this value is specified, development tools (for example, the debugger, remote command-line tools, and PIX) continue to work properly. The following table shows the details of the simulation profiles. To stop network simulation, run xbstress stop.To simulate a physical ethernet disconnect, run xbstress simulate network=disconnect.To simulate broken connectivity, run xbstress simulate network=broken.To simulate excellent connectivity, run xbstress simulate network=exc.To simulate average connectivity, run xbstress simulate network=avg. ![]() To simulate poor connectivity, run xbstress simulate network=min.The simulation command executes the following: Like other command-line tools, xbstress interprets the /X: command-line flag as the IP address or host name of the console. These profiles are based on figures from various sources that monitor the ongoing quality of internet connections. Xbstress (NDA topic) Authorization required has four preconfigured simulation profiles to easily simulate important network scenarios: minimum, average, excellent, and broken. Put all the nodes on the same link to minimize the effect of external sources of latency. Reliable connectivity with negligible packet loss.Higher available bandwidth than that of the simulation target.A clean network environment should meet the following criteria. When you use network simulation, provide a clean network environment to ensure that the only network issues are those caused by xbstress. This driver drops packets, injects latency, and limits throughput. For networking purposes, xbstress controls a specialized driver on Xbox One. For complete details, see xbstress (NDA topic) Authorization required. Use this tool to configure various console stressors, including network simulation. Network simulation is controlled with xbstress.exe, the command-line stress tool in the Microsoft Game Development Kit (GDK). Network simulations are an opportunity to gain insight into your game's behavior in variable conditions. Use your Xbox One Dev Kits to run network simulations for limited bandwidth, packet loss, and latency. To provide the best possible experience for a diverse user base, test your game in realistic customer environments. ![]() Available bandwidth and transmission reliability for users might be considerably less than what your development space has. User network environments can be imperfect and chaotic. ![]() Use this topic to understand how to simulate a reduced-capacity network on an Xbox One Dev Kit.
