Collaborative Research: NeTS-FIND: Value Flows and Risk Management Architecture for Future Internet

互联网简单的尽力而为的分组交换体系结构是其巨大成功和影响的核心。然而，当前的互联网体系结构既不允许(I)用户以足够的粒度指示他们的价值选择，也不允许(Ii)提供商管理投资新的创新的Qos技术所涉及的风险以及与其他提供商和用户的业务关系。为了实现这些灵活性，该项目研究了“合同转换”作为未来互联网的一种新范式。就像分组交换在互联网上实现灵活而高效的数据多路复用一样，合同交换网络将使风险和价值流能够灵活且经济高效地管理。智力优势：本项目专注于在多域服务质量合同的背景下设计合同交换框架。它解决了开发分散的域间协议机制所涉及的挑战，这些机制可以动态地组成复杂的端到端合同并为其定价。该项目将这种端到端的合同组合形式化为“合同路由”问题，类似于Qos路由算法。本研究还提出了一种在空间和时间上动态可组合的服务质量契约定价所必需的适当抽象。该项目利用金融工程技术为服务质量合同提供风险分担机制和资金保障结构。广泛影响：本研究将网络架构设计和金融工程工具结合在一起。这种跨学科的工作可以鼓励使用经济工具来解决垃圾邮件和DDoS攻击等安全问题。该项目将特别有利于互联网政策制定者。利用经济效率工具和金融衍生品管理风险有几个影响领域，如水、电、保险、实物期权分析、不确定情况下的投资，以及了解开源技术的影响。

The Internet's simple best-effort packet-switched architecture lies at the core of its tremendous success and impact. However, current Internet architecture allows neither (i) users to indicate their value choices at sufficient granularity nor (ii) providers to manage risks involved in investment for new innovative QoS technologies and business relationships with other providers as well as users. To allow these flexibilities, this project investigates "contract-switching" as a new paradigm for future Internet. Just like packet-switching enabled flexible and efficient multiplexing of data in the Internet, a contract-switched network will enable flexible and economically efficient management of risks and value flows.Intellectual Merit: This project focuses on the design of a contract-switching framework in the context of multi-domain QoS contracts. It addresses the challenges involved in the development of decentralized inter-domain protocol mechanisms that can dynamically compose and price complex end-to-end contracts. The project formulates this end-to-end contract composition as a "contract routing" problem, resembling the QoS routing algorithms. This research also develops an appropriate abstraction necessary for pricing of QoS contracts, dynamically composable contracts in space and time. The project employs financial engineering techniques to provide risk sharing mechanisms and money-back guarantee structures for the QoS contracts.Broader Impact: This research brings together network architecture design and financial engineering tools. This interdisciplinary work can inspire usage of economic tools for security problems like spam and DDoS attacks. The project will be especially beneficial to the Internet policy makers. Management of risks with economic efficiency tools and financial derivatives has several areas of impact such as water, electricity, insurance, real-options analysis, investment under uncertainty, and understanding the impact of open-source technologies.
