论文摘要
我们建议将网络领域提高到小包路由和转发方面的一流公民。通过在数据包标题中显式域，它可以负责承诺的服务和服务质量。由于该服务更容易受到监控，验证和补偿，因此可以培养一种新的业务模型，以迎合新兴的跨域，高价值和对性能敏感的应用程序。域级路由和转发基本上在网络协议堆栈中创建L3.5。我们使用新的路由标头扩展IPv6，以支持两种类型的转发方法。一个基于下一个域查找，另一个基于域级源路由。我们描述了各种设计细节，涵盖了标头格式，转发行为，路由协议，DNS和OAM。提出了几种用例以证明该方案潜力。该设计与当今的Internet体系结构兼容，并且可以在现有基础架构上逐步部署，仅需要中等更新。我们预计初步工作可以触发研究和互联网标准社区中的更多讨论和详细的设计。
We propose to raise network domain to the first-class citizen in packet routing and forwarding. By making domain explicit in packet header, it can be held responsible for committed services and quality of service. Since the service is easier to be monitored, verified, and compensated, a new business model catering for emerging cross-domain, high-value, and performance-sensitive applications can be fostered. The domain-level routing and forwarding essentially create a L3.5 in the network protocol stack. We extend IPv6 with new routing headers to support two types of forwarding approaches. One is based on the next domain lookup and the other realizes the domain-level source routing. We describe various design details covering header format, forwarding behavior, routing protocol, DNS, and OAM. Several use cases are presented to demonstrate the scheme potential. The design is compatible with today's Internet architecture and incrementally deployable on existing infrastructure with only moderate updates needed. We expect the preliminary work can trigger more discussion and detailed design in the research and Internet standard communities.
