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.

自 20 世纪 90 年代首次商业化以来，互联网的基本设计基本保持不变。现在，互联网已成为全球通信基础设施的核心，因此基本上不可能对其设计进行任何重大改变。不幸的是，需要进行此类更改。该项目旨在通过可扩展互联网的设计来解决这一悖论。这是一个合作项目，汇集了来自纽约大学、华盛顿大学和国际计算机科学研究所的研究人员。在大学在当今的互联网中，第 3 层有两个基本功能：(i) 连接所有第 2 层网络；(ii) 提供构建主机应用程序的数据包传送服务。可扩展互联网的关键方面是它的分裂。第 3 层仍然是第 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，第二层需要支持可扩展集的新层（称为第 3.5 层）。数据包的传输服务，从而处理提供构建主机应用程序的服务的第二个功能。通过这种方式，可扩展互联网设计使当前的互联网保持不变，但能够提供一组可扩展的新数据包传输服务，从而改善网络。互联网的性能和安全性。可扩展互联网设计是可增量部署的（即，任何应用程序或域都不会失去不变的连接），与经济激励兼容，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法。互联网将进一步发展如果采用可扩展互联网设计，将会对互联网的本质产生重大影响，特别是，向可扩展互联网的过渡不仅仅是功能上的一次性改变，而是对互联网的转变。单一且不变的服务模式（尽力而为的数据包传输）到不断发展和扩展的网络提供的服务。此外，在实现这一议程的过程中，研究人员将通过不断的努力来增加 STEM 劳动力的多样性。自己的研究小组和推广计划研究人员还将把他们的研究结果纳入他们的课程中，并免费提供材料。该项目的所有代码都可以在该项目的网站 ExtensibleInternet.org 上获得。该奖项反映了 NSF 的法定使命，并已获得通过使用基金会的智力优点和更广泛的影响审查标准进行评估，认为值得支持。
