摘　　要：互联网是网络空间的主要载体,“以内容为中心”的网络空间主流应用范式已经背离互联网“以地址为中心”的数据传输网络设计初衷,网络空间已经变成内容大数据的“露天堆放场”;不断涌现的内容大数据混乱失序、难于治理,构成了互联网可持续发展的严峻挑战。本文采取以内容驱动的播存次结构网络辅佐地址驱动的互联网主结构的共栖协同创新思路,提出了内容与地址双驱动的新型网络架构;分析了互联网体系结构的地址驱动特性及其所面临的挑战,讨论了近年来“以内容为中心”的网络研究方案及其局限性,阐述了内容与地址双驱动网络的设计思想、作为内容驱动基元的统一内容标签(UCL),给出了内容与地址双驱动网络参考模型,完成了单驱动网络、双驱动网络的对比分析。研究认为,内容与地址双驱动网络是一种兼具安全可信、普惠泛在、保障主权、易于治理等特性的新型网络架构,为破解单一地址驱动互联网的发展困局提供了合理可行的新思路。Internet is the main infrastructure of cyberspace,and the content-centric mainstream application paradigm of the cyberspace has deviated from Internet's original design intention of an address-centric data communication network.Hence the cyberspace has become an open-air dump of content big data.The emerging content big data characterized by chaos,disorder,and difficulty in governance brings severe challenges to the sustainable development of the Internet.Inspired by the idea of commensalism,a dual-meta network architecture driven by content and address is proposed in this paper which combines the primary structure of address-driven Internet with a secondary structure of content-driven broadcast-storage network.Specifically,the address-driven features and challenges of Internet architecture are analyzed,and some representative content-centric networking schemes and their limitations are discussed.Then,the design principles for dual-meta network architecture and the content-driven metadata of uniform content label are introduced.Eventually,a reference model of the dual-meta network architecture is given,and its differences compared with a single address-driven Internet architecture are analyzed.As an innovative network architecture characterized by security,trustworthiness,pervasiveness,guarantee of sovereignty,and easy governance,the dual-meta network architecture driven by content and address provides a feasible new way to solve the development dilemma faced by the single address-driven Internet architecture.
