日益增长的新业务需求和互联网经济的持续发展对网络通信与服务能力的要求都在不断增加，现有网络基础架构及由此构建的技术体系正面临一系列重大挑战，新型网络架构与关键技术已经成为全球新一轮科技革命和产业升级的核心，亟需研究我国新型网络技术创新的战略构想和发展路径。本文首先对当前网络技术面临的挑战进行分析研判，讨论了国内外新型网络领域的发展现状，概括了新型网络技术发展趋势；其次总结了我国在新型网络领域的差距和发展目标；最后从新型网络架构、网络全维可定义技术、多模态寻址路由技术、网络智慧化技术、内生安全构造等方面，提出了我国新型网络发展的关键技术和对策建议。在技术路线层面，建议发展开放、融合、安全的新架构，构建具有智慧化、多元化、个性化、高鲁棒、高效能等特性的新型网络环境；在国家政策层面，建议从技术研发、产业生态构建、市场准入等角度入手，给予相应的研发计划、示范应用、产品扶持等政策支持。

The ever-increasing demand for new businesses and the continuous development of the Internet economy have increasingly demanded network communications and service capabilities, and the infrastructure and the deriving technology system of the existing network still face a series of major challenges. New network architectures and key technologies have become the core of a new round of technological revolution and industrial upgrading in the world. Therefore, studying the strategic conception and development paths of new network technology innovation becomes an urgent need for China. In this article, we analyze the challenges faced by the current network technology, discuss the development status of new network fields in China and abroad, and summarize the development trend of new network technologies. Subsequently, we summarize the gaps and development goals of China in the new network field. Finally we propose the key technologies for the new network development in China, including new network architecture, network fulldimension definable technology, polymorphic addressing and routing technology, network intelligence technology, and endogenous security structure. From the aspect of technology roadmap, we suggest that an open, integrated, and secure new architecture should be established to build a new network environment that is intelligent, diversified, personalized, robust, and efficient. From the aspect of national policy, we suggest that support policies should be formulated regarding technology research and development, industrial ecology construction, and market access.
