论文摘要
无线电访问网络(RANS)的虚拟化正在成为未来无线系统的关键组成部分,因为它为RAN架构带来了敏捷性并提供了设计自由度。在本文中,我们调查并表征了虚拟RANS的计算和内存要求。为此,我们构建了一个虚拟运行测试床,利用SRSRAN开源移动通信平台和基于通用处理器的服务器。通过广泛的实验,我们介绍了计算和内存资源的消耗,并评估了系统性能。此外,我们构建回归模型,以预测系统行为,因为在不同的无线电传输设置下,连接用户的数量增加。这样一来,我们开发了一种方法和预测模型,可以帮助设计和优化虚拟架。
The virtualization of radio access networks (RANs) is emerging as a key component of future wireless systems, as it brings agility to the RAN architecture and offers degrees of design freedom. In this paper, we investigate and characterize the computational and memory requirements of virtual RANs. To this end, we build a virtual RAN test-bed leveraging the srsRAN open-source mobile communication platform and general-purpose processor-based servers. Through extensive experiments, we profile the consumption of computing and memory resources, and we assess the system performance. Further, we build regression models to predict the system behavior as the number of connected users increases, under diverse radio transmission settings. In so doing, we develop a methodology and prediction models that can help designing and optimizing virtual RANs.
