互联网经历了50余年的发展，在消费领域取得了巨大成功，带动了数字革命，引领了社会生产新变革，但面向实体经济却遇到了巨大挑战，网络体系架构的变革已经刻不容缓。本文总体分析了网络发展背景，探讨了面向2030的未来网络体系架构、关键技术和网络基础设施，明确了未来网络服务的典型应用场景，分析了未来发展趋势，希望能够为进一步优化完善由中国主导的网络技术体系、构建“网络空间人类命运共同体”提供有力支撑。
Internet has been developed for more than 50 years，and achieved great success in the field of consumption，driving the digital revolution and leading new changes in social production. However，it has encountered huge challenges when facing the real economy，which means the transformation of network architecture is urgent. This chapter generally analyzes the network development background. Furthermore，the architecture，key technologies and network infrastructure for future network 2030 are discussed. Moreover，the typical application scenarios of future network are defined. Finally，the related future development trend is analyzed. We hope to provide strong support for further optimizing and improving the network technology system led by China，and building a “Cyberspace Community of Common Destiny”.
