The Internet has become a critical infrastructure of the modern society, carrying the traffic of many mission-critical applications. As a result, the efficiency and reliability of the backbone networks of the Internet have major societal impacts. Uncertainties, which arise due to unpredictable network events and traffic variations, and the competitive, decentralized nature of the Internet, are major challenges to improve the efficiency, reliability, and availability of the Internet.This project develops effective and novel techniques to enable efficient and reliable traffic engineering in the presence of uncertainties. Its research consists of three major technical components: 1) COPE: Common-case Optimization with Penalty Envelope;2) SITE: Symbiotic Inter-domain Traffic Engineering; and 3) Integration of COPE and SITE. Together, they provide a complete traffic engineering solution.Broader Impacts: The research significantly advances the state of the art in traffic engineering. The techniques and toolkit resulted from the research deepens the understanding of traffic engineering and provides significant practical values in improving real IP network operations. In addition, the general principles behind the technical designs for addressing uncertainties have applications beyond traffic engineering.

互联网已成为现代社会的关键基础设施，载有许多关键任务应用程序的交通。结果，互联网骨干网络的效率和可靠性具有重大的社会影响。由于不可预测的网络事件和流量变化而引起的不确定性以及互联网的竞争性，分散性的性质是提高互联网效率，可靠性和可用性的主要挑战。在不认定的情况下，该项目开发了有效和新颖的技术，以启用有效和可靠的交通工程。它的研究由三个主要的技术组成部分组成：1）COPE：通过惩罚信封的公共案例优化； 2）站点：共生室内交通工程； 3）COPE和站点的整合。 他们共同提供了完整的交通工程解决方案。Broader的影响：研究大大提高了交通工程中最新技术的状态。研究和工具包是由研究加深对交通工程的理解，并为改善实际IP网络运营提供了重要的实用价值。此外，解决不确定性的技术设计背后的一般原则除了交通工程以外的应用程序。
