java - 在测试中模拟可变网络条件

Question

我正在使用 GWT 在 GAE/J 上编写应用程序。在我的开发机器上，一切正常 - RPC 总是成功返回，并且顺序相同。当我部署到 AppEngine 时，一些 RPC 失败，并且它们经常以不同的顺序返回。

测试环境如何包含这种可变性？有什么好的工具可以为应用引擎处理这个问题吗？

NIST Net是一个成熟的网络模拟器。

The NIST Net network emulator is a general-purpose tool for emulating performance dynamics in IP networks. The tool is designed to allow controlled, reproducible experiments with network performance sensitive/adaptive applications and control protocols in a simple laboratory setting. By operating at the IP level, NIST Net can emulate the critical end-to-end performance characteristics imposed by various wide area network situations (e.g., congestion loss) or by various underlying subnetwork technologies (e.g., asymmetric bandwidth situations of xDSL and cable modems).
