摘要

虚拟时间中仿真和仿真的结合要求在虚拟时间中赋予仿真执行爆发一个持续时间，并且在这个共同的虚拟时间基础上协调仿真执行和仿真执行。本文展示了一个用于协调虚拟时间仿真的开源工具TimeKeeper如何与三种不同的现有软件仿真/仿真集成:CORE、ns-3和S3F。我们描述了为支持这种集成而对工具所做的每一种修改，并检查了旨在评估组合模型准确性的实验。Timekeeper允许比以前实现的更严格的同步仿真和模拟。

Conjoining Emulation and Network Simulators on Linux Multiprocessors

Conjoinment of emulation and simulation in virtual time requires that emulated execution bursts be ascribed a duration in virtual time, and that emulated execution and simulation executions be coordinated within this common virtual time basis. This paper shows how an open source tool TimeKeeper for coordinating emulations in virtual time can be integrated with three different existing software emulations/simulations: CORE, ns-3, and S3F. We describe for each of these the modifications made to the tools to support this integration, and examine experiments designed to assess the accuracy of the combined models. Timekeeper permits much tighter sychronization emulation and simulation than has ever been achieved before.
