最后，通过自适应边界值方法进行检测，能够及时发现异常流量行为，说明该模型应用于网络流量预测是可行、有效的。
Finally, abnormal behaviors of network traffic can be found on time through test of adaptive boundary value method, which proves that the model is feasible and effective.
比方说，把null值传入一个并未编写如何处理null值的方法中，这就是一种边界情况。
It's the situation where, for instance, someone passes a null value to a method not coded to handle nulls.
边界值测试是一种常用的功能测试方法。
