In the thirty-odd years since the advent of the Internet architecture, new uses and abuses, along with the realities that come with being a fully commercial enterprise, are pushing the Internet into realms that its original design neither anticipated nor gracefully accommodates. These pressures have revealed several limitations of the Internet architecture, and the Internet's increasing ubiquity and importance have made these flaws all the more evident and urgent. However, it is far easier to complain about the Internet architecture than it is to produce a better design. This proposal accepts that challenge, by proposing a clean-sheet redesign of the Internet. The proposed design is based on a new naming system that names services (or data) and endpoints (hosts) separately from network locations, and incorporates notions of delegation and indirection. Moreover, these service and endpoint identifiers are flat, with no hierarchical structure.Such architecture naturally handles host mobility, multihoming, and data replication and migration, and incorporates middleboxes in an architecturally clean manner. In addition, it simplifies interdomain routing, by adopting a new global addressing structure that makes explicit the administrative domain to which a host belongs. The interdomain routing protocol exchanges routes based on these flat domain identifiers (instead of today's IP prefixes that cause many problems), together with flexible mappings of flat end-host identifiers, to enable more flexible routing policies for ISPs and hosts.

自互联网架构出现以来的30多年里，新的用途和滥用，沿着完全商业化的现实，正在将互联网推向其最初设计既没有预料到也没有优雅地适应的领域。这些压力揭示了互联网架构的一些局限性，而互联网的日益普及和重要性使这些缺陷变得更加明显和紧迫。然而，抱怨互联网架构比产生更好的设计要容易得多。这项提案接受了这一挑战，提出了互联网的全新设计。建议的设计是基于一个新的命名系统，命名服务（或数据）和端点（主机）从网络位置分开，并纳入委托和间接的概念。此外，这些服务和端点标识符是扁平的，没有层次结构。这种架构自然地处理主机移动性，多宿主，数据复制和迁移，并以架构上干净的方式合并中间盒。此外，它还通过采用新的全局寻址结构来简化域间路由，该结构明确了主机所属的管理域。域间路由协议基于这些平面域标识符（而不是导致许多问题的当今IP前缀）以及平面端主机标识符的灵活映射来交换路由，从而为ISP和主机启用更灵活的路由策略。
