当代互联网已经从一个学术基础设施发展成为一个巨大的商业网络，成为人类交流不可或缺的信息平台，但也有其固有的局限性，如复杂的管理和手动配置。为了克服这些限制，基本的互联网架构在过去十年中掀起了前所未有的创新浪潮，并引入了一种有前途的网络范式，即软件定义网络（SDN），通常被称为“网络中的激进新想法”。SDN提供了许多潜在的好处，例如增强的配置，改进的性能，以及鼓励网络架构和运营的创新，同时由于缺乏全球网络范围的信息而面临前所未有的挑战。数据驱动思想的兴起开启了科学研究的第四范式时代，并将未来网络的设计理念从小规模数据转向大规模数据。我们认为，SDN中数据驱动的信息平面的存在可以解决这些挑战。在本文中，我们明确提出了一个数据驱动的信息平面，并专门扩展了SDN架构。我们首先概述了SDN的发展，然后通过将数据驱动的信息平面引入到普遍接受的SDN参考架构中来说明一种新的SDN范例。最后，我们概述了新出现的挑战，并讨论了由数据驱动的信息平面引发的进一步研究的未来方向。
The contemporary Internet has evolved from an academic infrastructure to a tremendous commercial network, serving as an indispensable information platform for human communications, but with inherent limitations such as complicated management and manual configuration. To overcome these limitations, the basic Internet architecture has unleashed an unprecedented wave of innovation over the past decade, and introduced a promising networking paradigm, software-defined networking (SDN), often referred to as a "radical new idea in networking." SDN offers numerous potential benefits such as enhanced configuration, improved performance, and encouraged innovation in network architectures and operations, while undergoing unprecedented challenges due to the lack of global network-wide information. Nowadays, the emerging data-driven thought opens the era of the fourth paradigm for science research and transfers the design philosophy of future networks, based on the large-scale data rather than the small-scale data. We argue that the existence of a data-driven information plane in SDN can address these challenges. In this article, we explicitly propose a data-driven information plane and extend the SDN architecture specifically. We first overview the evolution of SDN, and then illustrate a novel SDN paradigm by introducing a data-driven information plane into the commonly accepted SDN reference architecture. Finally, we outline emerging challenges and discuss future directions for further research triggered by a data-driven information plane.
