NGFI，即下一代前传接口，是用于C-RAN（云无线电接入网络）的有前途的前传接口。NGFI用于连接RCC（无线电云中心）和RRS（无线电远程系统），以避免传统CPRI（通用公共无线电接口）的缺点。在本文中，我们研究了基于NGFI的C-RAN。我们使用OpenAirInterface（OAI）开源4G/5G移动的通信软件和基于GPP（通用处理器）的服务器和个人计算机来构建OAI C-RAN测试床。我们还使用OAI的源代码在这个OAI C-RAN测试平台上运行性能分析，以了解这个测试平台的行为。本文的目的是建立OAI C-RAN系统的综合性能分析方法和结果，并使用这些结果来帮助设计和优化OAI C-RAN系统。根据分析结果，我们可以决定对系统软件的哪些部分进行优化，以提高系统的速度和内存使用效率。
NGFI, the Next Generation Fronthaul Interface, is a promising fronthaul interface for the C-RAN (Cloud Radio Access Network). NGFI is used to connect RCC (Radio Cloud Center) and RRS (Radio Remote System) in order to avoid the drawbacks of traditional CPRI (Common Public Radio Interface). In this paper we investigate the NGFI-based C-RAN. We use the OpenAirInterface (OAI) open source 4G/5G mobile communication software and GPP (general purpose processor) based servers and personal computers to build an OAI C-RAN testbed. We also use the source codes of OAI to run the performance profiling on this OAI C-RAN testbed to understand the behavior of this testbed. The purpose of this paper is to build the comprehensive performance profiling methods and results on the OAI C-RAN system, and to use these results to help designing and optimizing the OAI C-RAN system. Based on the results, we could decide which part of the system software to optimize to improve the system speed and the efficiency of memory usage.
