Although the fifth-generation wireless communication network (5G) has made much progress in improving the quality of user experience by providing large bandwidth transmission, it only provides the connectivity services between user equipments (UEs) and the network. With the sensing and intelligence are envisioned to become the native capability of the sixth-generation communication network (6G), there is an urgent need for a new network architecture enabling the “on-path-data-processing”, to make better leverage of distributed and ubiquitous computation resources and data. Thus, we propose a Data Plane in 6G network, which is independent of existing User Plane, aiming at constructing data pipelines based on various data service requirements. It systematically provides the collaboration of data among multiple network components with arbitrary topology with the support for on-path-data-processing. Based on this, we propose three data forwarding control protocols, guaranteeing the operation of Data Plane by providing data forwarding in any topology. Simulation experiments demonstrate the good scalability and efficiency of the three protocols in Data Plane.

尽管第五代无线通信网络（5G）通过提供大带宽传输在提高用户体验质量方面取得了很大进步，但它仅提供用户设备（UE）与网络之间的连接服务。随着感知和智能被设想为第六代通信网络（6G）的原生能力，迫切需要一种能够实现“路径数据处理”的新网络架构，以更好地利用分布式和无处不在的计算资源和数据。因此，我们在 6G 网络中提出了一个独立于现有用户平面的数据平面，旨在构建基于各种数据服务需求的数据管道。它系统地提供了具有任意拓扑结构的多个网络组件之间的数据协作，并支持在途数据处理。基于此，我们提出了三种数据转发控制协议，通过在任何拓扑中提供数据转发来保证数据平面的运行。仿真实验证明了三种协议在数据平面中具有良好的可扩展性和效率。
