A seamless interworking between network function virtualization (NFV) and software defined networking (SDN) to orchestrate network services for the 5G systems is very fundamental for network slice creation. The orchestration of large scale network slices across multiple administrative as well as technological domains with heterogeneous resources and a distributed form of slice management can benefit from harnessing existing NFV orchestration (NFVO) solutions. In this regard, this article presents a network service orchestration and configuration convergence framework that is capable of providing a large scale network slicing solution for 5G network operators. Using this framework, 5G network operators can orchestrate and configure network slices directly from their infrastructure and that of credible registered slice providers who have resources for the orchestration of only a subset of the overall network slice. The framework is equipped with mechanisms that allow a distributed form of slice configuration and management.

实现5G网络切片网络服务编排和配置融合框架的真正部署


网络功能虚拟化 (NFV) 和软件定义网络 (SDN) 之间的无缝互通为 5G 系统编排网络服务对于网络切片创建至关重要。跨多个管理和技术领域的大规模网络切片编排具有异构资源和分布式切片管理形式，可以受益于利用现有的 NFV 编排 (NFVO) 解决方案。对此，本文提出了一种网络服务编排和配置融合框架，能够为5G网络运营商提供大规模网络切片解决方案。使用此框架，5G 网络运营商可以直接从其基础设施以及可靠的注册切片提供商的基础设施中编排和配置网络切片，这些提供商拥有仅用于编排整个网络切片的子集的资源。该框架配备了允许分布式形式的切片配置和管理的机制。
