Collaborative Research: NeTS-FIND: SWITCHNET: A Switched Internetworking Architecture with Contracted Services

互联网面临着许多挑战，包括安全、管理和控制。该研究项目探索了未来的互联网/网络架构，该架构基于一个经过充分验证的分层架构，但尚未在全球层面进行测试。该体系结构包括灵活的寻址方案和紧凑的四层协议栈。从社会经济和商业的角度来看，互联网架构的根本变化将具有潜在的变革性。因此，要解决的科学问题是多学科的。研究了新网络架构的技术和社会经济可行性，以及采用这种激进变化的可能模式。智力上的优点：这项研究提出了一个完全分层的架构，在这个设计中，在不同的层次上有足够的冗余，是如何产生一个健壮的、可扩展的结构的。该解决方案将“交换决策”，即流量如何从一个点移动到另一个点的管理，分配到通信提供商层次结构的所有级别：它允许在流量流动的任何地方独立管理流量。取而代之的是高度依赖的路由和网络管理架构。该研究将展示该架构如何健壮和稳定，并具有未来增长的潜力。该体系结构的一个关键贡献是可扩展和灵活的分层寻址方案，其中关键的网络功能被降级到层次结构中的不同级别，这也提供了更好的管理和控制。该研究包括通过在该架构中连接各种无线网络来进行概念验证。更广泛的影响：SWITCHNET研究产生的新网络架构可能会对通信网络的经济产生根本性的变化，并最终对经济和社会产生非常大的影响。概念架构几乎具有理想的可扩展性。它比目前的体系结构管理起来要简单得多。作为SWITCHNET可管理性广泛影响的一个例子，通过从根本上实现更好的提供商控制，该架构将为识别和击退拒绝服务的新方法打开大门，这是一种经济和国家急需的能力。此外，这项研究可以为实现全光目标提供突破性的架构，从而解决创建更节能网络的国家挑战。实现这种纯光通信基础设施的方法一直在寻求。

The Internet faces many challenges, including security, management and control. The research project explores a future Internet/networking architecture based on a well-proven hierarchical architecture that is untested at global levels. The architecture includes a flexible addressing scheme and a compact four layer protocol stack. The radical change to the Internet architecture would be potentially transformative from a socioeconomic and business perspective. The scientific problems to be addressed are hence multidisciplinary. The technical and socioeconomic feasibility for the new network architecture, as well as the likely patterns of adoption for such a radical change are investigated. Intellectual merit: This research asks how a fully hierarchical architecture, with adequate redundancy at different levels in this design, results in a robust structure that is also scalable. The solution distributes the "switching decisions," the management of how traffic moves from one point to another, to all levels of a hierarchy of communications providers: it allows the traffic to be managed independently wherever the traffic is flowing. The replaces present highly interdependent routing and network management architecture. The research will show how this architecture is robust and stable with a potential for future growth. A key contribution of the architecture is a scalable and flexible hierarchical addressing scheme, where key network functions are relegated to different levels in the hierarchy, and this also provides better management and control. The research includes proof-of-concept by interfacing diverse wireless networks in the architecture.Broader impact: A new network architecture resulting from the SWITCHNET research could create radical changes in the economics of communications networks and ultimately have a very large impact on the economy and society. The conceptual architecture is almost ideally scalable. It is very much simpler to manage than the present architecture. As an example of the broad impact of SWITCHNET manageability, by enabling fundamentally better provider control, the architecture would open the door to new methods of identifying and pushing back denial of service, an economically and nationally much needed capability. Furthermore, this research could provide the breakthrough architecture for attaining the all-optical goal and thus address that national challenge to create a more energy-efficient network. Approaches to achieving such a purely optical communications infrastructure have long been sought.
