NeTS-FIND: An Internet Architecture for User-Controlled Routes

提案编号：0627166PI：杨晓伟机构：加州大学欧文分校标题：NeTS-FIND：用户控制路由的互联网架构摘要本项目正在开发一种互联网架构，使用户或其终端系统能够选择其数据包通过网络的路径。这种由用户控制的路线在经济和技术上都是可取的。从经济上讲，用户控制的路由是保持ISP市场竞争力的关键因素，就像长途运营商选择对电话产生了持久的影响一样。从技术上讲，用户控制路由是提高网络通信性能和可靠性的基本手段。这是因为它们允许终端系统同时使用多个不同的路径，并减少对具有不良特征的单个网络路径的依赖。与用户控制路由相关的关键技术难点在于可扩展性和鲁棒性。这个项目直接解决了这些问题。它涉及以下组件的开发：1)可扩展的域间路由协议，该协议将策略约束的网络域级映射分发给用户，并允许用户显式地制定域级路由；2)允许各种应用程序利用路径多样性的终端系统协议栈；3)防止用户以危及整体路由稳定性的方式快速切换路径的算法和协议；4)减轻与用户控制路由相关的安全威胁的技术（例如源地址欺骗，多路径拒绝服务攻击）。如果成功，这项工作将产生积极的经济影响，促进互联网服务提供商的竞争，在网络通信的可靠性和性能方面产生可衡量的技术改进，并有助于教育。在这个项目中开发的算法、协议和软件将通过研究出版物和项目网站进行传播。

Proposal Number: 0627166PI: Xiaowei YangInstitution: University of California, IrvineTitle: NeTS-FIND: An Internet Architecture for User-Controlled RoutesAbstractThis project is developing an Internet architecture that enables users or their end-systems to select the paths their packets take through the network. Such user-controlled routes are desirable for both economic and technical reasons. Economically, user-controlled routes are a key factor in maintaining the competitiveness of the ISP marketplace, just as long distance carrier selection has had a lasting impact on telephony. Technically, user-controlled routes provide a fundamental means for improving the performance and reliability of network communications. This is because they allow end systems to use multiple diverse paths concurrently and reduce the dependence on a single network path that has undesirable characteristics. The key technical difficulties associated with user controlled routes lie in the areas of scalability and robustness. This project directly addresses these issues. It involves the development of the following components: 1) a scalable inter-domain routing protocol that distributes policy-constrained domain-level maps of the network to users and allows them to explicitly formulate domain-level routes; 2) an end system protocol stack that allows various applications to take advantage of path diversity; 3) algorithms and protocols that prevent users from rapidly switching paths in a fashion that jeopardizes the overall routing stability; 4) techniques that mitigate the security threats associated with user-controlled routes (e.g. source address spoofing, multi-path denial of service attacks). If successful, this work will have a positive economic impact that fosters ISP competition, result in measurable technical improvements in terms of reliability and performance of network communications, and contribute to education. Algorithms, protocols, and software developed in this project will be disseminated through research publications and a project web-site.
