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.

自从1990年代首次商业化以来，互联网的基本设计一直保持不变。现在，互联网是我们全球通信基础架构的核心，基本上不可能以任何重要的方式改变其设计。不幸的是，需要进行此类更改以改善互联网的性能和安全性。该项目旨在通过称为“可扩展互联网”的设计来解决这个悖论。这是一个合作项目，汇集了霍利奥克山学院，纽约大学，华盛顿大学和加利福尼亚大学伯克利分校的国际计算机科学研究所的研究人员。在今天的互联网上，第3层具有两个基本功能：（i）连接所有第2层网络和（ii）在哪些主机应用程序上提供了包装服务。可扩展的Internet的关键方面是将第3层分为两层。第一个保留第3层并可以使用当前的Internet协议（IP），它处理了连接第2层网络的第一个功能。第二个需要一个新的层（称为3.5层），该层支持可扩展的数据包输送服务集，因此处理了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，可扩展的互联网设计使当前的Internet保持不变，但能够提供一套可扩展的新包装交付服务，以提高Internet的性能和安全性。可扩展的Internet设计在逐步部署（即，没有变化的应用程序或域名都不会失去连接性），与经济激发和经济激励措施相兼容，可以继续进化为新的需求。因此，它为互联网提供了一种实用的方式，可以远远超出其目前的设计。如果采用了可扩展的互联网设计，它将对互联网的性质产生重大影响。特别是，向可扩展的互联网过渡不仅是一次性功能的一次变化，而且还将互联网从单个和不变的服务模型（最佳效果数据包）转变为不断发展且不断扩展的网络提供的服务集。此外，在追求这个Agernda时，调查人员将通过自己的研究小组和各自部门的宣传计划进行持续的努力来增加STEM劳动力的多样性。调查人员还将将其结果纳入他们的课程，并使材料免费提供。该项目的所有代码将在该项目的网站上可用于ExtensibleInternet.org.org。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响审查标准来通过评估来获得的支持。
