The emergence of new applications has fostered a number of attempts to add functionalities to the minimalist Internet core. However, the adoption of enhancements to the Internet has either been slow, failed entirely, or limited to special-purpose private networks. The key reasons for this failure are extensibility and scalability: First, IP networks were not designed to be extensible at the internetworking level. Second, proposals for new network layer services often require that vast amounts of state information be managed in the core network infrastructure, thus, introducing scalability bottlenecks which exacerbate the existing scalability problem of the growing Internet. Today, the development and deployment of advanced services on the Internet has reached a crossroads: efforts to add new services have quickly encountered scalability problems, yet new services are in critical demand and must be rapidly and widely deployed. The research goal is to develop truly scalable services for each of the three fundamental components of the Internet's infrastructure: information communication, replication, and storage. Taking a new and unified approach to the seemingly conflicting requirements for scalability and sophisticated network services, the researchers propose to develop: 1. Scalable Performance-Predictable Communication: a new foundation for quality-of-service communication via a scalable edge-based architecture. 2. Scalable Multicast for Efficient Data Dissemination: a self-organizing multicast infrastructure scalable to many spontaneously-formed groups. 3. Scalable Storage for Next Generation Information Services: an infrastructure which brings informationcloser to users and enables scalable third-party information storage services. 4. Design Principles of Scalable Services: a multi-faceted approach for the development and deploymentof scalable services in the global Internet, under consideration of economic models, industrial structure,theories and algorithms, engineering, and deployment. Thus, this project proposes to develop architectures and methodologies for deploying scalable services in the global Internet. The impact of this project will be to provide the theoretical underpinnings, basic architecture, and a prototype implementation for the information communication of the global Internet of the 21st century. An integral part of this project is the dissemination of results and the infiltration of standard organizations with the concepts developed within this project, and innovative approaches to educate the next generation of engineers for the future Internet.

新应用程序的出现促进了为极简主义互联网核心添加功能的多次尝试。然而，互联网增强功能的采用要么进展缓慢，要么完全失败，要么仅限于特殊用途的专用网络。这一失败的主要原因是可扩展性和可伸缩性：首先，IP网络的设计不是为了在网际网络级别进行扩展。其次，新网络层服务的提议通常要求在核心网络基础设施中管理大量状态信息，从而引入可扩展性瓶颈，这加剧了不断增长的互联网的现有可扩展性问题。今天，互联网上高级服务的开发和部署已经走到了十字路口：添加新服务的努力很快就遇到了可扩展性问题，但新服务的需求非常迫切，必须迅速和广泛地部署。研究目标是为互联网基础设施的三个基本组件中的每一个开发真正可扩展的服务：信息通信、复制和存储。对于看似相互冲突的可扩展性和复杂网络服务的需求，研究人员采取了一种新的统一方法，他们建议开发：1.可扩展的性能可预测通信：通过可扩展的基于边缘的体系结构为服务质量通信奠定新的基础。2.用于高效数据分发的可扩展多播：可扩展到许多自发形成的组的自组织多播基础设施。3.下一代信息服务的可扩展存储：使信息更接近用户并支持可扩展的第三方信息存储服务的基础设施。4.可扩展服务的设计原则：在考虑经济模型、产业结构、理论和算法、工程和部署的情况下，在全球互联网上开发和部署可扩展服务的多方面方法。因此，该项目建议开发用于在全球互联网中部署可伸缩服务的体系结构和方法。该项目的影响将是为21世纪的全球互联网的信息交流提供理论基础、基本架构和原型实现。该项目的一个组成部分是传播成果，并利用在该项目内形成的概念向标准组织渗透，以及为未来的互联网培养下一代工程师的创新方法。
