        人类正在进入一个“人机物”三元融合的万物智能互联时代，需要一种新型信息基础设施，即全球规模的高通量低熵算力网，形象地简称为“信息高铁”。文章介绍了信息高铁的愿景，包括基础性需求、关键科学技术问题和系统结构。与互联网、云计算、大数据、物联网等现有网络计算系统相比，信息高铁的目标是原生支持“人机物”三元融合和低熵有序，降低系统无序的负面影响，提升系统通量与应用品质。

        The world is entering a new era of human-cyber-physical ternary computing with diverse intelligent applications over trillions of devices. This calls for a new type of cyberinfrastructure characterized by a planet-scale, high-goodput, low-entropy computing network, colloquially named Information Superbahn. This article highlights the vision of Information Superbahn, including fundamental requirements, key scientific problems, and a candidate system architecture. The goal of building the Information Superbahn is to natively support humancyber-physical systems and low-entropy computing modes, to reduce the effects of systems disorder. Compared with existing network computing systems, such as Internet, cloud computing, big data and Internet of Things, Information Superbahn aims to achieving higher system goodput and application quality of service.
