CAREER: Weaving a Code Tapestry: A Compiler Directed Framework for Scalable Network Emulation

0133840斯里尼迪·瓦拉达拉扬弗吉尼亚理工学院和州立大学职业生涯：编织代码挂毯：可扩展网络仿真的编译器指导框架在本研究中，我们提出了一个新的可扩展的网络仿真试验台，它在一个框架内既支持模拟又支持直接代码执行范例。为了体现互联网的规模和异构性，试验台的规模可以扩展到数万到数十万个网络节点。第一个主要挑战在于开发能够表示单个进程内的网络协议栈的有向图关系的编程模型，而无需手动修改协议栈或网络应用程序。其次，试验台的巨大规模要求我们解决应用间上下文切换时间、内存使用和并行离散事件模拟方面的问题，所有这些都给可伸缩性带来了瓶颈。

EIA-0133840 Srinidhi Varadarajan Virginia Polytechnic Institute & State University CAREER: Weaving a Code Tapestry: A Compiler Directed Framework for Scalable Network Emulation In this research, we propose a new scalable network emulation test-bed that supports both the simulation as well as direct code execution paradigms within a single framework. In order to represent the scale and heterogeneity of the Internet, the test-bed scales to tens to hundreds of thousands of network nodes. The first major challenge lies in developing programming models that can represent the digraph relationship of network protocol stacks within a single process, without manually modifying either the protocol stack or network applications. Secondly, the enormous scope of the test bed requires us to address problems in inter application context switch time, memory usage and parallel discrete event simulation, all of which present bottlenecks to scalability.
