"NFV的发展目标-清晖pmp讲义标准版v1.6.gabble01-第12章" 随着通信行业的不断发展,网络技术经历了从模拟通信到IP化通信的转变,并逐渐迈向与互联网和IT技术的深度融合。通信网络的下一个重大变革将是IT化,这涉及到CT(通信技术)与IT的深度整合,即保持CT的网络特性与服务质量,同时采用IT化的内部实现方式。这一变化标志着通信业进入了通信4.0时代,以ICT(信息通信技术)的深度融合为核心。 SDN(Software Defined Networking,软件定义网络)和NFV(Network Functions Virtualization,网络功能虚拟化)作为IT化技术的重要代表,预计在2016年至2020年间迎来关键的部署阶段。NFV的目标是将传统的物理网元逻辑上拆分为硬件、虚拟层和上层网络功能三部分,并引入MANO(Management and Orchestration,管理和编排)系统,以实现端到端的管理。为了充分释放NFV的潜力,业界追求的是三层完全解耦,允许任意组合,从而实现跨域资源共享和灵活的业务编排。 NFV技术白皮书V2.0(2018年)由SDN/NFV产业联盟发布,强调了虚拟网元的技术要求、三层解耦虚拟层技术、MANO技术以及分布式存储技术等方面的发展。白皮书旨在加速NFV产业进程,推动国内NFV自主产业生态的构建。各通信运营商和设备制造商如中国电信、中国移动、华为、中兴等积极参与了白皮书的编制工作。 在NFV的实施过程中,硬件层面需满足特定的技术要求,包括服务器形态、配置和管理,如BIOS设置和硬件FCAPS(故障、配置、计费、性能和服务)管理。虚拟层技术则涉及基础功能、计算虚拟化等,以确保虚拟环境的稳定性和高效性。 面对NFV的发展,业界也面临着挑战,包括技术标准的统一、安全性、网络性能优化以及跨厂商互操作性等问题。尽管如此,NFV带来的网络灵活性、成本降低和快速服务部署能力使其成为通信行业未来发展的重要方向。
