论文摘要
软件定义网络（SDN）的演变在下一代网络（NGN）的开发中发挥了重要作用。 SDN作为一个可编程的网络，可以随时提供服务提供服务，这引起了学术界和行业的浓厚兴趣。在本文中，关于SDN的进步超过了传统网络的全面调查。该论文涵盖了与SDN，SDN及其相关技术的功能架构以及OpenFlow标准/协议有关的历史演变，包括与网络元素（NES）（NES）（例如光学开关）接口的基本概念。此外，还进行了选择性架构调查。我们在软件定义的异质网络上提出的架构指出，新技术可以在网络技术领域开放新的远景，这将有助于处理巨大的互联网流量，并帮助基础架构和服务提供商动态自定义其资源。此外，已经详细阐述了当前的研究项目和各种活动，以将不同的标准发展组织（SOD）标准化为NGN为NGN，以判断这项技术如何朝着标准化迈进。
The evolution of software defined networking (SDN) has played a significant role in the development of next-generation networks (NGN). SDN as a programmable network having service provisioning on the fly has induced a keen interest both in academic world and industry. In this article, a comprehensive survey is presented on SDN advancement over conventional network. The paper covers historical evolution in relation to SDN, functional architecture of the SDN and its related technologies, and OpenFlow standards/protocols, including the basic concept of interfacing of OpenFlow with network elements (NEs) such as optical switches. In addition a selective architecture survey has been conducted. Our proposed architecture on software defined heterogeneous network, points towards new technology enabling the opening of new vistas in the domain of network technology, which will facilitate in handling of huge internet traffic and helps infrastructure and service providers to customize their resources dynamically. Besides, current research projects and various activities as being carried out to standardize SDN as NGN by different standard development organizations (SODs) have been duly elaborated to judge how this technology moves towards standardization.
