Research on high throughput rate complex event detection technique in manufacturing IOT

复杂事件处理能非常有效地检测到事件流中有价值的模式,高吞吐率意味着单位时间内获取更多有价值的信息。为复杂事件处理提出一种提高吞吐率的查询技术,通过聚集活动实例栈中的连接,并批量执行序列构造,减少了相同连接的遍历,降低了序列构造处理的运行频率,从而提高了复杂事件处理的吞吐率。仿真实验表明:提出的方案相比于SASE提出的传统方案,吞吐率有数倍的提升。

Complex event processing can be very effective in detecting valuable patterns from event streams,and high-throughput means more valuable information per unit time. Present a technology to improve the throughput of complex event processing queries. By aggregating link in active instance stacks and batch execution sequence structure,reduce the traversal same connection,reduce the operating frequency of the sequence structure processing. Thereby,improve the throughput of complex event processing. Simulation results show that compared with SASE,throughput of the proposed scheme is improved by several times.
