NeTS-FIND: Collaborative Research: Enabling Future Internet innovations through Transit wire (eFIT)

eFIT（通过传输线路实现未来互联网创新）项目旨在通过确保架构级别的强大通用连接来实现未来的创新。创新源于摩尔定律提供的丰富而廉价的计算资源，以及互联网提供的普遍连接。计算资源可能会变得更加丰富和便宜，但是Internet提供的通用连接性正面临重大挑战，正如网络地址转换（NAT）的普遍使用和全球路由表的加速增长所证明的那样。当前的Internet架构通过将用户网络和Internet服务提供商（isp）置于相同的地址和路由空间来提供端到端的连接。用户网络和互联网服务提供商有着不同的目的、不同的特点，并且正朝着几乎相反的技术方向发展。然而，现有体系结构所强加的网络用户和isp之间的相互依赖给未来的互联网创新造成了一个主要障碍。当一个系统的规模以数量级增长时，形式的变化就变得必要了。eFIT设计通过首先关注通用连接来实现创新。eFIT将用户网络和提供商网络置于不同的地址和路由空间中，消除了两个世界之间的相互依赖性。通过eFIT，用户可以简单地将互联网传输核心视为具有强大通用连接性的传输线，而提供商则可以免受用户网络爆炸式增长所带来的各种问题的影响。因此，用户和提供商都可以在没有任何架构限制的情况下自由地进行创新。更广泛的影响：这种新的体系结构设计将对研究社区、服务提供商和互联网用户产生广泛的影响。eFIT使研究生能够探索安全等基础问题的新方向。更广泛地说，它将把Internet用户从当前的架构限制中解放出来，并鼓励应用程序创新的新浪潮。

The eFIT (Enabling Future Internet innovations through Transit wire) project aims to enable future innovations by ensuring strong universal connectivity at the architectural level. Innovations are enabled by the abundant and affordable computing resources provided by Moore's Law, and universal connectivity provided by the Internet. Computing resources are likely to become more plentiful and affordable, but the universal connectivity provided by the Internet is facing major challenges, as demonstrated by the prevalent use of network address translation (NAT) and accelerated growth of the global routing table. The current Internet architecture provides end-to-end connectivity by putting both user networks and Internet service providers (ISPs) in the same address and routing spaces. User networks and ISPs have different purposes, distinct characteristics, and are moving in almost opposite technological directions. However the inter-dependency between network users and ISPs imposed by the existing architecture creates a major roadblock to future Internet innovations.When a system grows larger in size by orders of magnitude, a change in form becomes necessary. The eFIT design enables innovation by first focusing on universal connectivity. eFIT places user networks and provider networks in different address and routing spaces, removing the inter-dependency between the two worlds. With eFIT, users can simply treat the Internet transit core as a transit wire with strong universal connectivity, while providers are insulated from the various problems caused by explosive growth in user networks. Therefore both users and providers will be able to innovate freely on their own without any architectural constraints.Broader Impact: This new architecture design will have a broad impact on the research community, service providers, and Internet users. eFIT enables graduate students to explore new directions for fundamental problems such as security. Even more broadly, it will liberate Internet users from the current architectural constraints and encourage a new wave of application innovations.
