Limited domains were defined conceptually in RFC 8799 to cater to requirements and behaviours that extend the dominant view of IP packet delivery in the Internet. This paper argues not only that limited domains have been with us from the very beginning of the Internet but also that they have been shaping innovation of Internet technologies ever since, and will continue to do so. In order to build limited domains that successfully interoperate with the existing Internet, we propose an architectural framework as a blueprint. We discuss the role of the IETF in ensuring continued innovation in Internet technologies by embracing the wider research community's work on limited domain technology, leading to our key insight that Limited Domains are not only considered useful but a must to sustain innovation.

被认为有用的有限域

有限域在 RFC 8799 中在概念上进行了定义，以满足扩展 Internet 中 IP 数据包传输的主要观点的要求和行为。本文认为，有限域不仅从互联网一开始就伴随着我们，而且从那时起它们一直在塑造互联网技术的创新，并将继续如此。为了构建与现有互联网成功互操作的有限域，我们提出了一个架构框架作为蓝图。我们讨论了 IETF 在确保互联网技术持续创新方面的作用，它接受了更广泛的研究社区在有限域技术方面的工作，得出了我们的关键见解，即有限域不仅被认为是有用的，而且是维持创新的必要条件。
