EAGER: Collaborative Research: Towards an Extensible Internet

互联网的基本设计自20世纪90年代首次商业化以来基本保持不变。现在互联网是我们全球通信基础设施的核心，基本上不可能以任何重大方式改变其设计。不幸的是，这些变化是需要提高互联网的性能和安全性。这个项目的目的是解决这个矛盾的设计称为可扩展的互联网。这是一个合作项目，汇集了来自霍利奥克山学院，纽约大学，华盛顿大学，和国际计算机科学研究所在伯克利的加州大学的研究人员。在今天的互联网，第3层有两个基本功能：（i）连接所有的第2层网络和（ii）提供包传递服务，主机应用程序建立在其上。 可扩展互联网的关键方面是它将第3层分为两层。第一个仍然是第3层，可以使用当前的互联网协议（IP），处理连接第2层网络的第一个功能。第二个需要一个新的层（称为层3.5），它支持一组可扩展的分组传递服务，从而处理第二个功能，即提供构建主机应用程序的服务。以这种方式，可扩展因特网设计使当前的因特网保持不变，但是能够提供一组可扩展的新分组递送服务，这将提高因特网的性能和安全性。没有未改变的应用或域将失去连接性），与经济激励相容，并且可以随着新需求的出现而继续发展。因此，它为互联网提供了一种实用的方式，使其远远超出目前的设计。如果采用可扩展互联网设计，将对互联网的性质产生重大影响。特别是，过渡到可扩展的互联网不仅仅是功能上的一次性变化，而是将互联网从单一和不变的服务模型（尽力而为的数据包交付）转变为不断发展和扩展的网络提供的服务。此外，在追求这一议程的过程中，研究人员将通过在各自的研究小组和各自部门的外联计划中不断努力，努力增加STEM劳动力的多样性。研究人员还将把他们的成果纳入他们的课程，并免费提供材料。该项目的所有代码将在该项目的网站ExtensibleInternet.org上提供。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估来支持。

The Internet’s basic design has remained largely unchanged since it first became commercial in the 1990s. Now that the Internet is the centerpiece of our global communications infrastructure, it is essentially impossible to alter its design in any significant way. Unfortunately, such changes are needed to improve the Internet’s performance and security. This project aims to resolve this paradox with a design called the Extensible Internet. This is a collaborative project which brings together investigators from Mount Holyoke College, New York University, the University of Washington, and International Computer Science Institute at the University of California at Berkeley.In today’s Internet, layer 3 has two basic functions: (i) connect all layer 2 networks and (ii) provide the packet delivery services on which host applications are built. The key aspect of the Extensible Internet is that it splits layer 3 into two layers. The first, which remains layer 3 and can use the current Internet Protocol (IP), handles the first function of connecting layer 2 networks. The second requires a new layer (called layer 3.5) that supports an extensible set of packet delivery services, and thus handles the second function of providing the services on which host applications are built. In this way, the Extensible Internet design leaves the current Internet unchanged but is able to provide an extensible set of new packet delivery services that will improve the Internet’s performance and security.The Extensible Internet design is incrementally deployable (i.e., no unchanged applications or domains would lose connectivity), compatible with economic incentives, and can continue to evolve as new requirements arise. As such, it provides a practical way for the Internet to evolve far beyond its current design. If the Extensible Internet design is adopted, it would have a significant impact on the nature of the Internet. In particular, transitioning to the Extensible Internet is not just a one-time change in functionality, but transforms the Internet from a single and unchanging service model (best-effort packet delivery) to an evolving and expanding set of network-provided services. In addition, in pursuing this agenda, the investigators will work to increase the diversity of the STEM workforce through ongoing efforts in their own research groups and the outreach programs in their respective departments. The investigators will also incorporate their results into their courses and make the material freely available.All of the code from this project will be available on the project’s website at ExtensibleInternet.org.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
