摘　　要：数据要素的高效配置对于实现传统产业数字化转型尤为重要。网络的供给能力不仅要求数据报文的低时延、大带宽特性,更需要数据报文的低抖动和确定性。确定性网络技术是构建无损、确定、可靠的广域传播能力的关键。提出了面向广域确定性网络的控制面关键技术及设计思想,并详细阐述了实现确定性网络感知、业务规划和流量调度的具体方案。通过开展试验验证和应用测试,证明了系统结构的有效性,满足确定性网络的管理和调度需求。The efficient allocation of data elements is particularly important for achieving digital transformation in traditional industries.Network supply capabilities not only require low latency and high bandwidth for data packets,but also require low jitter and certainty in data packets.Deterministic networking technology is the key to build lossless,reliable,and deterministic wide-area communication capabilities.The key control technologies and design concepts for wide-area deterministic networking were proposed,and the specific plans for achieving deterministic networking perception,service planning,and traffic scheduling were elaborated on.Through experimental verification and application testing,the effectiveness of the system structure is proven and it meets the management and scheduling needs of deterministic networking.
