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，当前的互联网架构既不允许（i）用户以足够的粒度指示他们的价值选择，也不允许（ii）提供商管理涉及对新的创新QoS技术的投资以及与其他提供商和用户的业务关系的风险。为了让这些灵活性，本项目调查“合同转换”作为未来互联网的一个新的范例。就像分组交换使互联网中的数据能够灵活和高效地复用一样，合同交换网络将使风险和价值流的管理变得灵活和经济高效。智力优点：本项目侧重于在多域QoS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面临的挑战，这些机制可以动态地组成和定价复杂的端到端合同。该项目制定了这个端到端的合同组成作为一个“合同路由”的问题，类似的QoS路由算法。这项研究还开发了一个适当的抽象必要的QoS合同，在空间和时间的动态组合合同定价。该项目采用金融工程技术提供风险分担机制和退款保证结构的QoS contracts.Broader影响：这项研究汇集了网络架构设计和金融工程工具。这项跨学科的工作可以激发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决策者。利用经济效率工具和金融衍生工具进行风险管理具有多个影响领域，如水、电、保险、实物期权分析、不确定性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.
