一些流行的模拟和仿真环境无法考虑商业交换机和路由器的真实数据包转发行为。这种模拟或仿真的不准确可能会对结果造成巨大的和定性的影响。在本文中,我们提出了一个基于测量的路由器和其他转发设备的模型,我们使用该模型来模拟不同流量条件下的两种不同的思科路由器。我们的模型的结构是与设备无关的,但需要特定于设备的参数。我们构建了一个分析工具,并使用它在几个小时内得出路由器参数表。我们的初步结果表明,我们的模型可以近似于思科路由器。参数表的紧凑性和模型的简单性使其有可能用于高保真模拟,同时保持模拟的可扩展性。
Several popular simulation and emulation environments fail to account for realistic packet forwarding behaviors of commercial switches and routers. Such simulation or emulation inaccuracies can lead to dramatic and qualitative impacts on the results. In this paper, we present a measurement-based model for routers and other forwarding devices, which we use to simulate two different Cisco routers under varying traffic conditions. The structure of our model is device-independent, but requires device-specific parameters. We construct a profiling tool and use it to derive router parameter tables within a few hours. Our preliminary results indicate that our model can approximate the Cisco routers. The compactness of the parameter tables and simplicity of the model makes it possible to use it for high-fidelity simulations while preserving simulation scalability.
