Network Functions Virtualization Management and Orchestration (NFV-MANO) provides a standardized approach for the management and effortless deployment of (virtual) services. Although NFV-MANO initially focused on the deployment of services over datacenters, the introduction of fully softwarized network architectures even for the wireless network creates fertile ground for the re-conception of the manner through which the underlying hardware is managed. In this article, we consider the case of an open experimentation testbed, with focus on wireless networking, and adopt the Open Source MANO framework for provisioning virtual services on top of the experimentation equipment. We extend the Virtual Infrastructure Managers (VIMs) of the NFV-MANO architecture in two well-known frameworks (Openstack and OpenVIM) for the testbed in order to create and handle virtualized wireless network interfaces, hosted on the generic networking nodes of the testbed. Through our contributions, existing VNFs can be deployed over the testbed interconnected over wireless links, specified during the on-boarding phase. The extensions are introduced transparently to the existing operation of the platform, in order to allow the portability of network services and network functions to other instances as well. We focus on providing virtual functions inter-networked over wireless links, which traditionally are not handled by the framework, and allow easier interaction of the end-users with the testbed. We benchmark the framework in terms of performance and analyze the deployment case of a softwarized 5G Radio Access Network in a real testbed deployment.

无线网络切片上的服务编排：测试平台设置和集成

网络功能虚拟化管理和协调（NFV-MANO）为管理和轻松部署（虚拟）服务提供了一种标准化方法。尽管NFV-MANO最初专注于在数据中心上部署服务，但是引入完全软化的网络体系结构（甚至是无线网络）也为重新构想管理底层硬件的方式创造了沃土。在本文中，我们考虑了一个开放实验平台的案例，该平台侧重于无线网络，并采用开放源代码MANO框架在实验设备之上提供虚拟服务。我们在用于测试平台的两个众所周知的框架（Openstack和OpenVIM）中扩展了NFV-MANO架构的虚拟基础架构管理器（VIM），以便创建和处理虚拟化的无线网络接口，这些接口托管在测试平台的通用网络节点上。通过我们的贡献，现有的VNF可以部署在通过无线链路互连的测试平台上，这是在入职阶段指定的。这些扩展透明地引入到平台的现有操作中，以允许网络服务和网络功能也可移植到其他实例。我们专注于提供通过无线链路互连的虚拟功能，这些功能传统上不会由框架处理，并且允许最终用户与测试平台进行更轻松的交互。
