尽管嵌入式系统的进步，信息和通信技术在近几十年的发展，工业系统仍有望因演变为不断进步的科学。我们知道，网络，物理系统（CPS）是工业4.0推动者。在工业4.0的背景下，物联网的产业网络（IIoT）正在推广和广告产业升级。

In order to implement the flexible, customizable, and efficient industrial systems, all related enabling technologies (e.g., industrial wireless networks, cloud computing, bigdata, and social networks) or devices (e.g., intelligent robots and flexible conveyors) must be developed as well for being integrated into IIoT systems. However, we still face some challenges: (1) how to realize the efficient interaction and coordination between IIoT for the Industry 4.0 production; (2) how to design a configurable data acquisition node in order to meet more application scenarios; and (3) how to fully utilize heterogeneous network to transfer all kinds of information. Fortunately, Software-Defined Networking (SDN) possesses the feature that can manage network services through abstraction of higher-level functionality. Therefore, enlightened by SDN, there is a new idea for the information interaction of industrial environment by introducing software-defined IIoT to make the network more elastic.
