实验工具是学术界和工业界研究社区对涉及故障排除或改变已部署网络规划的新网络技术进行设计评估的关键因素。物理软件定义无线电（SDR）实验平台为无线通信系统的快速原型设计提供了一种解决方案。然而，基于SDR的实验平台成本高昂，导致实验设置中的可扩展性受限。尽管如此，网络模拟器、仿真器和新的测试平台已引起越来越多的关注。基于仿真的研究原型设计可通过允许成本与灵活性之间的权衡，与真实通信网络和基于SDR的平台区分开来。本文考察了Mininet-RAN仿真工具，该工具除了无线接入网（RAN）建模外，还提供了一种无需部署整个RAN基础设施即可测试开放RAN智能控制器（RIC）服务的方法。Mininet-RAN通过结合一些最佳的仿真器特性、硬件测试平台和模拟器，创建虚拟网络元素，如主机、L2/L3设备、控制器和链路。通过运行标准实践Unix/Linux网络应用程序和网络栈的当前代码，Mininet-RAN能够将真实的网络数据流量模式传递给RIC，涉及无线系统KPI动态生成的最重要方面。我们为O-RAN联盟定义的前两个涉及V2X和UAV的用例提供了Mininet-RAN的基本代码。xApps正在O-RAN SC近实时RIC中实现，Mininet-RAN提供了一个闭环验证环境。
英文摘要
Experimental tools are a key factor in both academic and industrial research communities to create design evaluations of new networking technologies that involve troubleshooting or changing the planning of deployed networks. Physical Software-Defined Radio (SDR) experimental platforms enable a design solution for the quick prototyping of wireless communication systems. However, SDR-based experimental platforms incur high costs, which leads to scalability limitations in the experimental settings. Having said this, network simulators, emulators, and new testbeds have attracted increasing attention. Emulation-based research prototyping can be distinguished from real communication networks and SDR-based platforms by allowing a tradeoff between cost and flexibility. This paper examines the Mininet-RAN emulation tool, which, as well as Radio Access Network (RAN) modeling, provides a way to test Open RAN Intelligent Controller (RIC) services without the need to deploy an entire RAN infrastructure. The Mininet-RAN creates virtual network elements, such as hosts, L2/L3 devices, controllers, and links, by combining some of the best emulator features, hardware testbeds, and simulators. By running the current code of standard practice Unix/Linux network applications and network stack, the Mininet-RAN enables real-world network data traffic patterns to be delivered to the RIC, regarding the most significant aspect of the dynamic generation of wireless system's KPIs. We provide the basic code of Mininet-RAN for the first two O-RAN Alliance-defined use cases involving V2X and UAV. The xApps are being implemented in O-RAN SC near-RT RIC, with Mininet-RAN which provides a closed-loop validation environment.
