On Enhancing the Stability and Scalability of Interdomain Routing

本计画包括研究跨网域路由协定之稳定性与可扩充性。该研究不仅解决了当前域间路由协议边界网关协议（BGP）的问题，而且还开发了新的域间路由协议，可以促进快速收敛，并确保可靠性。在增强域间路由方面，鲁棒配置和流量工程能力是研究的重要组成部分。这包括对BGP功能的基本理解和对当前BGP的最小扩展集的研究。稳健的配置能力还需要网络配置目标的高级规范。研究团队将对域间路由的基本问题进行系统研究，包括流量工程能力和域间路由可扩展性之间的权衡，避免持续振荡的路由策略指南以及这些指南与流量工程能力之间的权衡，减少路由协议收敛延迟，并通过指定高级路由策略语义来增强路由可靠性。该项目的一个组成部分是教育研究生和本科生的网络的管理和配置，以及创建周围的域间路由问题的认识和学生之间的兴趣。

This project includes the research activities to obtain the stability and scalability of the inter-domain routing protocols. The proposed research will not only address issues on the current interdomain routing protocol, Border Gateway Protocol (BGP), but also develop new interdomain routing protocols that can facilitate fast convergence and ensure reliability. In enhancing interdomain routing, robust configuration and traffic engineering capability are the integral part of the research. This includes fundamental understanding of BGP capability and investigating the minimum set of extensions to the current BGP. Robust configuration capability also requires high-level specification of the network configuration goal. The research team will perform systematic studies of fundamental issues on interdomain routing, including tradeoffs between traffic engineering capability and scalability of interdomain routing, routing policy guidelines to avoid persistent oscillation and the tradeoff between these guidelines and traffic engineering capability, reducing routing protocol convergence delay, and enhancing routing reliability by specifying high-level routing policy semantics. One component of this project is to educate graduate and undergraduate students on the management and configuration of the networks as well as to create awareness and interest among students on the issues surrounding interdomain routing.
