网络即服务:新的机遇前景

Network as a Service: The New Vista of Opportunities

Junaid Qadir, Nadeem Ahmed, Faqir Zarrar Yousaf, Ali Taqweem

摘要:

与计算行业相比,网络行业在从具有有限抽象的封闭生态系统发展到具有定义良好的复杂高级抽象的更开放的生态系统方面进展缓慢。这导致了僵化的互联网架构,阻碍了创新,而且过于复杂。幸运的是,近年来网络的快速发展令人兴奋,出现了突出的趋势,使我们处于重大范式转变的尖端。特别地,诸如云计算、软件定义网络(SDN)和网络虚拟化之类的技术的出现正在推动“网络即服务”(NaaS)的新愿景,在该新愿景中,以云计算风格灵活且高效地管理网络。这些技术有望促进架构和技术创新,同时简化网络服务的调试、编排和组合。在本文中,我们将向读者介绍这些技术。在未来几年,云计算、SDN和网络虚拟化的趋势将进一步加强彼此的价值主张,NaaS将日益成为新网络调试的主导模式。

英文摘要:

The networking industry, compared to the compute industry, has been slow in evolving from a closed ecosystem with limited abstractions to a more open ecosystem with well-defined sophisticated high level abstractions. This has resulted in an ossified Internet architecture that inhibits innovation and is unnecessarily complex. Fortunately, there has been an exciting flux of rapid developments in networking in recent times with prominent trends emerging that have brought us to the cusp of a major paradigm shift. In particular, the emergence of technologies such as cloud computing, software defined networking (SDN), and network virtualization are driving a new vision of `networking as a service' (NaaS) in which networks are managed flexibly and efficiently cloud computing style. These technologies promise to both facilitate architectural and technological innovation while also simplifying commissioning, orchestration, and composition of network services. In this article, we introduce our readers to these technologies. In the coming few years, the trends of cloud computing, SDN, and network virtualization will further strengthen each other's value proposition symbiotically and NaaS will increasingly become the dominant mode of commissioning new networks.
