The Network Function Virtualization (NFV) trend is making substantial progress and has gained wide support across the industry. The concept of NFV is driven largely by the convergence of cloud computing and traditional telecommunications networks, increasingly powerful chips, and the diversification of service demands. This document describes the changes to network architecture that will be brought about by NFV. It also explains how SoftCOM, Huawei’s vision for future architecture, implements this trend.
The telecommunications industry is evolving from proprietary equipment networks to IT-based data center networks that employ technologies such as cloud computing, software-defined networking (SDN) and NFV, Internetized operations, and big data analytics to provide a variety of ICT services to end users.
With the SoftCOM strategy, Huawei is reshaping the architecture, functions, services, and operational and maintenance modes of telecommunications networks. NFV will play a vital role in this process. Based on the concept of NFV, NE nodes under the SoftCOM architecture are classified into a three-level structure that features horizontal convergence and vertical de-coupling. The three levels are basic hardware, open cloud platform, and service software. There are also new design requirements put forward for NFV service targets.
CloudEdge, one of the most important NFV use cases, aims to virtualize all network components in edge,
CloudEdge, which aims to virtualize all network components in edge, such as EPC, CDN, and BRAS, is an innovative solution that Huawei developed for NFV implementation. The Huawei CloudEdge solution is composed of hardware infrastructure, an operating system, network APPs, and MANO. This one-stop solution makes it possible to implement NFV and enlarge the business scope for operators using an easy approach.
With the CloudEdge solution, network elements and applications are implemented as a set of virtual resources including computing, storage, and networking capabilities instead of proprietary hardware. This mechanism enables on-demand resource allocation rather than fixed occupation of hardware in a conventional way. Based on Huawei Cloud OS FusionSphere, CloudEdge can ensure carrier-grade performance and reliability for users.
Huawei is committed to helping carriers succeed with its innovative network equipment and technologies. NFV can drastically shorten the technological innovation cycle, accelerate new service launch speed, reduce operation and maintenance costs, eliminate the closeness of traditional telecommunications networks, build an open ecological environment, and promote an open industrial culture. NFV will help carriers face the challenges of accelerated ICT convergence and the slowed development of traditional telecommunications networks. NFV has already undergone proof-of-concept tests as well as scenario testing. The next step is to work with carriers to transform technological innovation into business innovation and to explore the business value of NFV.
