为了简化物联网服务的部署和管理，网络功能虚拟化（NFV）和服务功能链（SFC）是很有前途的解决方案，许多研究人员已经开展了这些主题。为了增强以前研究工作的可靠性，本文提出了一个基于Docker和Kubernetes的以物联网为中心的SFC编排框架。该框架通过满足服务需求以及计算和网络资源约束来实现自动物联网服务部署。在这样的部署中，我们应用虚拟网络功能（VNF）/服务功能（SF）布局问题，以实现资源的有效利用。我们设置了一个目标函数，以最小化SF实例和通信的数量，并建立了一个数学模型的基础上，线性规划（ILP）。为了验证它，我们实现了一个模型的框架，并进行数值评估和真实的实验的性能进行评估。从评估结果中，我们证实，所提出的方法可以减少SF放置的数量和SF实例之间的通信数量。
In order to simplify deployment and management of IoT services, Network Function Virtualization (NFV) and Service Function Chaining (SFC) are promising solutions, and much researchers have conducted these topics. To enhance the reliability of former research efforts, in this paper, we propose an orchestration framework for IoT-centric SFC by using Docker and Kubernetes. The framework enables an automatic IoT service deployment by satisfying service requirements and computing and network resource constraints. In such deployment, we apply a Virtual Network Function (VNF)/Service Function (SF) placement problem to achieve efficient utilization of the resources. We set an objective function as minimizing both numbers of SF instances and communications and build a mathematical model based on Integer Linear Programming (ILP). To validate it, we implement a model for the framework and evaluate the performances by carrying out a numerical evaluation and a real experiment. From the evaluation results, we confirm that the proposed approach can reduce the number of SF placements and the number of communications among SF instances.
