There is now a significant and growing functional gap between the public Internet, whose basic architecture has remained unchanged for several decades, and a new generation of more sophisticated private networks. To address this increasing divergence of functionality and overcome the Internet's architectural stagnation, we argue for the creation of an Extensible Internet (EI) that supports in-network services that go beyond best-effort packet delivery. To gain experience with this approach, we hope to soon deploy both an experimental version (for researchers) and a prototype version (for early adopters) of EI. In the longer term, making the Internet extensible will require a community to initiate and oversee the effort; this paper is the first step in creating such a community.

通过使其可扩展来振兴公共互联网

几十年来基本架构保持不变的公共互联网与更复杂的新一代专用网络之间存在着巨大且不断扩大的功能差距。为了解决这种日益增长的功能差异并克服 Internet 的架构停滞，我们主张创建一个可扩展的 Internet (EI)，以支持超出尽力而为数据包交付的网络内服务。为了获得这种方法的经验，我们希望尽快部署 EI 的实验版本（用于研究人员）和原型版本（用于早期采用者）。从长远来看，使互联网具有可扩展性需要一个社区来发起和监督这项工作；本文是创建这样一个社区的第一步。
