NeTS-NBD: Internet Revolution through Flat Resolution

在互联网架构出现的三十多年里，新的使用和滥用，以及作为一个完全商业企业所带来的现实，正在将互联网推向其原始设计既没有预料到也没有优雅地容纳的领域。这些压力暴露了互联网架构的几个局限性，互联网日益无处不在和日益重要，使这些缺陷变得更加明显和紧迫。然而，抱怨互联网架构要比设计出更好的设计容易得多。这项提案接受了这一挑战，提出了一项干净的互联网重新设计方案。建议的设计基于一种新的命名系统，该命名系统将服务(或数据)和端点(主机)与网络位置分开命名，并结合了委派和间接的概念。此外，这些服务和终端标识符是平面的，没有分层结构。这种架构自然处理主机移动性、多宿主以及数据复制和迁移，并以架构干净的方式整合中间盒。此外，它还采用新的全局寻址结构，明确主机所属的管理域，从而简化域间路由。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今天的IP前缀)以及平面终端-主机标识符的灵活映射来交换路由，从而为互联网服务提供商和主机实现更灵活的路由策略。

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.
