Today, the Network Slicing technology is massively addressed by the research community. However, Network Slice (NS) modelling details from Standards Developing Organizations (SDOs) are not yet well considered for End-to-End (E2E) NS implementations. In addition, each SDO develops standards targeting only a specific part of the NS architecture. Therefore, based on a profound analysis of the major existing works, this article explains first (i) a general architecture that clarifies the basic E2E network slicing functionality before diving deep into domain-specific visions. Then, (ii) it focuses at providing a survey stitching together the NS modelling works in Radio Access Networks (RAN), Core Networks (CN) and also Transport Networks (TN). The end goal is to clarify the E2E Network Slicing process from the service order request to the NS deployment and life-cycle management. Last, as there is no consensus on a specific information model in the Transport network domains (iii) we provide our vision on how several data models, developed by IETF working groups, can be integrated together in the context of the ACTN architecture in order to provision and manage Transport NSs.

端到端5G网络切片模型的全面调查
如今,研究领域已广泛使用网络切片技术。但是,对于端到端(E2E)NS实施,尚未很好地考虑标准开发组织(SDO)的网络切片(NS)建模细节。此外,每个SDO都制定仅针对NS体系结构特定部分的标准。因此,在对现有主要作品进行深入分析的基础上,本文首先说明(i)一种通用体系结构,该体系结构将在深入探讨特定于领域的愿景之前阐明基本的E2E网络切片功能。然后,(ii)着重于提供将无线接入网(RAN),核心网(CN)和传输网(TN)中的NS建模工作拼接在一起的调查。最终目标是阐明从服务订单请求到NS部署和生命周期管理的E2E网络切片过程。最后,由于对传输网络领域中的特定信息模型尚无共识(iii),我们提供了我们的愿景,即如何在ACTN架构的背景下将IETF工作组开发的多个数据模型集成在一起。供应和管理运输NS。
