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

EIA-0133840 Srinidhi Varadarajan弗吉尼亚理工学院&州立大学职业生涯：编织代码挂毯：在这项研究中，我们提出了一个新的可扩展的网络仿真测试床，支持模拟以及在一个单一的框架内的直接代码执行范例。 为了体现互联网的规模和异构性，测试床可扩展到数十万到数十万个网络节点。 第一个主要挑战在于开发能够在单个进程中表示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，测试床的巨大范围要求我们解决应用程序间上下文切换时间，内存使用和并行离散事件模拟等问题，所有这些都是可扩展性的瓶颈。

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.
