5G QoS:安全功能对延迟的影响

5G QoS: Impact of Security Functions on Latency

Sebastian Gallenmüller, Johannes Naab, Iris Adam, Georg Carle

摘要:

网络切片被认为是第五代(5G)通信网络的关键使能器。移动网络运营商可以部署网络切片--为期望特定服务质量(QoS)的特定服务定制的完整逻辑网络。新的业务模式,如面向垂直行业客户的网络切片即服务产品,需要协商服务水平协议(SLA)合同,网络提供商需要自动执行机制,以确保切片实例化和操作期间的QoS。在本文中,我们专注于超可靠低延迟通信(URLLC)。我们提出了一种基于现成的硬件和开源软件的安全功能的软件架构,并通过一系列的测量表明,可以实现URLLC服务的严格要求。作为一个现实世界的例子,我们使用入侵防御系统(IPS)Snort进行实验,以证明安全功能对延迟的影响。我们的研究结果导致创建一个模型,预测系统负载,仍然满足URLLC的延迟要求。我们在https://gallenmu.github.io/low-latency上充分披露了本文中提出的工件,包括pcap跟踪、测量工具和绘图脚本。

英文摘要:

Network slicing is considered a key enabler to 5th Generation (5G) communication networks. Mobile network operators may deploy network slices -- complete logical networks customized for specific services expecting a certain Quality of Service (QoS). New business models like Network Slice-as-a-Service offerings to customers from vertical industries require negotiated Service Level Agreement (SLA) contracts, and network providers need automated enforcement mechanisms to assure QoS during instantiation and operation of slices. In this paper, we focus on ultra-reliable low-latency communication (URLLC). We propose a software architecture for security functions based on off-the-shelf hardware and open-source software and demonstrate, through a series of measurements, that the strict requirements of URLLC services can be achieved. As a real-world example, we perform our experiments using the intrusion prevention system (IPS) Snort to demonstrate the impact of security functions on latency. Our findings lead to the creation of a model predicting the system load that still meets the URLLC latency requirement. We fully disclose the artifacts presented in this paper including pcap traces, measurement tools, and plotting scripts at https://gallenmu.github.io/low-latency.
