摘要
工业4.0、《中国制造2025》战略不断推动工业生产向网络化、智能化升级,基于SDN&TSN的网络架构以其灵活性、开放性、实时性、高效集中管控的特点普适于未来工业网络各种业务需求。SDN架构的控制平面与数据平面分离机制便于集中管控工业网络资源,灵活、合理地为不同QoS需求的业务分配不同的网络资源集,提高网络利用率的同时保障时间敏感应用的实时性需求。TSN主要技术包括时间窗口整形、队列调度、流过滤、路径控制等。未来工业网络架构的趋势是将SDN和TSN技术有机结合,通过集中式控制实现网络动态规划与调度以满足工业应用实时性要求。
Made-in-China 2025 and ＂Industry 4.0＂ strategy continually promote industrial production upgrade to networked and intelligent. The network architecture based on SDN＆TSN is suitable for various business needs of future industrial networks because of its flexibility, openness, real-time and efficient centralized management. The separation mechanism of control plane and data plane facilitate centralized management and control of industrial network resources, flexibly and reasonably allocating different network resource sets for different QoS requirements, improving network utilization while ensuring delay requirements for time-sensitive applications. The main technologies of TSN include time window shaping, queue scheduling, flow filtering, and path control. The trend of future industrial network architecture is to combine SDN and TSN technologies to achieve dynamic network planning and scheduling through centralized control and then meet the real-time requirements of industrial applications.
