One of the main challenges to use network functions virtualization (NFV) is to properly manage the life cycle of the virtualized network functions (VNFs). Current solutions based on the ETSI standard NFV architectural framework are complex and require the knowledge of a myriad of details of the underlying infrastructure. This work proposes a VNF manager (VNFM) specification that supports different platforms and VNF utilization scenarios. The proposed VNFM specification defines a set of APIs, modules, and components, for both the end user and the back-end that provide the fundamental set of operations required to fully manage the VNF life cycle. Our primary goal is to simplify the operations, in particular reducing the need for the network operator to know the details of the virtualized infrastructure. Note that the proposed solution fills a gap and complements the ETSI VNFM module. A prototype was implemented, and experimental results show the effectiveness and low overhead of the proposed solution.

超越 VNFM：填补 ETSI VNF 管理器的空白，全面支持 VNF 生命周期操作

使用网络功能虚拟化 (NFV) 的主要挑战之一是正确管理虚拟化网络功能 (VNF) 的生命周期。当前基于 ETSI 标准 NFV 架构框架的解决方案很复杂，需要了解底层基础架构的大量细节。这项工作提出了支持不同平台和 VNF 使用场景的 VNF 管理器 (VNFM) 规范。提议的 VNFM 规范为最终用户和后端定义了一组 API、模块和组件，提供完全管理 VNF 生命周期所需的基本操作集。我们的主要目标是简化操作，特别是减少网络运营商了解虚拟化基础架构细节的需要。请注意，提议的解决方案填补了空白并补充了 ETSI VNFM 模块。实现了一个原型，实验结果表明所提出的解决方案的有效性和低开销。
