摘要： 构建了一个交换式工业以太网实时性评价实验平台。该实验平台不但可以根据工厂生产现场的实际网络负载构造出对应的实时和非实时流量以及激发“端口竞争”，而且可以对工业以太网实时性情况进行监测和评价。实验验证了实验平台的系统准确性和稳定性。

Abstract: A test-bed is designed for real-time evaluation of switched industrial Ethernet. The test-bed can not only generate real-time and non-real-time traffic like network load in factory but can stimulate “compete the same outport”. The test-bed can be used to evaluate the real-time behavior of switched industrial Ethernet. The experiment proves the accuracy and stability of the test-bed.

Key words: Industrial Ethernet, Real-time behavior, Evaluation
