在本文中，我们描述了一种新的方法，用于在物联网（IoT）设备的数据在网络边缘部分处理的情况下管理服务功能链。我们的框架由两种新兴技术支持，软件定义网络（SDN）和基于容器的虚拟化，这确保了灵活性，易编程性和多功能性方面的几个好处。这些功能非常适合物联网应用日益严格的要求，并允许动态和自动化的网络服务链。一个广泛的性能评估，这已经通过一个测试平台进行，旨在了解我们提出的框架如何执行计算开销，网络带宽和能源消耗方面。通过考虑典型物联网网关的限制，我们的评估试图揭示该框架在低功耗节点上的实际可部署性。
In this paper, we describe a new approach for managing service function chains in scenarios where data from Internet of Things (IoT) devices is partially processed at the network edge. Our framework is enabled by two emerging technologies, Software-Defined Networking (SDN) and container based virtualization, which ensure several benefits in terms of flexibility, easy programmability, and versatility. These features are well suitable with the increasingly stringent requirements of IoT applications, and allow a dynamic and automated network service chaining. An extensive performance evaluation, which has been carried out by means of a testbed, seeks to understand how our proposed framework performs in terms of computational overhead, network bandwidth, and energy consumption. By accounting for the constraints of typical IoT gateways, our evaluation tries to shed light on the actual deployability of the framework on low-power nodes.
