IoT devices have become an integral part of our lives and the industry. Many of these devices run real-time systems or are used as part of them. As these devices receive network packets over IP networks, the network interface informs the CPU about their arrival using interrupts that might preempt critical processes. Therefore, the question arises whether network interrupts pose a threat to the real-timeness of these devices. However, there are few tools to investigate this issue. We present a playground which enables researchers to conduct experiments in the context of network interrupt simulation. The playground comprises different network interface controller implementations, load generators and timing utilities. It forms a flexible and easy to use foundation for future network interrupt research. We conduct two verification experiments and two real world examples. The latter give insight into the impact of the interrupt handling strategy parameters and the influence of different load types on the execution time with respect to these parameters.

PIERES：一个在物联网中实时嵌入式系统上进行网络中断实验的游乐场

物联网设备已成为我们生活和整个行业不可或缺的一部分。这些设备中有许多运行实时系统或用作其中的一部分。当这些设备通过IP网络接收网络数据包时，网络接口会使用可能抢占关键进程的中断来通知CPU它们的到达。因此，出现了一个问题，网络中断是否会对这些设备的实时性构成威胁。但是，很少有工具可以调查此问题。我们提供了一个游乐场，使研究人员可以在网络中断模拟的背景下进行实验。运动场包括不同的网络接口控制器实现，负载生成器和计时实用程序。它为将来的网络中断研究奠定了灵活且易于使用的基础。我们进行了两个验证实验和两个真实示例。后者可以深入了解中断处理策略参数的影响以及不同负载类型对这些参数的执行时间的影响。
