ATM交换结构是实现LHC实验数据采集系统的高性能并行事件生成器的良好候选者。我们正在通过模拟和事件生成器演示程序的实施来研究其可行性。研究了事件生成器特征流量模式对交换机的影响，并提出了避免交换机拥塞的方法。已经开发了事件构建算法和数据采集协议。测量与演示和模拟研究的比较。测量的可扩展性进行了讨论。
ATM switching fabrics are good candidates to implement high performance parallel event builders for the future data acquisition systems of the LHC experiments. We are studying their feasibility through simulations and implementation of event builder demonstrators. The impact of the event builder characteristic traffic pattern on the switch has been studied and methods to avoid congestion in the switch have been proposed. Event building algorithms and data acquisition protocols have been developed. Measurements made with a demonstrator and comparisons with simulation studies are presented. The scalability of the measurements is discussed.
