Near-perfect quality of service in wired and wireless IP networks

这项发现拨款将探索一种新的调度算法，该算法可以在普通分组交换网络和基于基础设施的无线Mesh网络(WMN)上获得近乎完美的服务质量(Qos)。在过去的二十年里，互联网对社会产生了前所未有的影响。与无线电、电报、电话、电视和个人电脑等其他颠覆性技术相比，互联网是北美大多数家庭适应速度最快的技术之一。互联网上的新服务的前景是巨大的，其中包括远程医疗、远程机器人系统和智能公路系统。然而，还有一些重大的技术问题需要解决。2007年，美国国家科学基金会(NSF)启动了一项名为“全球网络创新环境”(GENI)的新计划，目标是解决自互联网诞生以来一直“困扰着互联网”的问题。这些问题包括服务质量、安全性、可靠性以及无线技术的完美集成。这些问题是如此复杂，以至于Geni计划采取了一种“从头开始”的方法，即整个互联网可能会从头开始重新设计。该申请人开发了一种新的调度算法。该算法可以为一般分组交换网络(包括有线IP网络和基于基础设施的无线Mesh网络)中的静态提供的多媒体流量获得近乎完美的服务质量。需要资金来更深入地探索这一算法。

This discovery grant will explore a new scheduling algorithm which can achieve near-perfect Quality of Service (QoS) over general packet-switched networks and infrastructure-based Wireless Mesh Networks (WMNs). The Internet has had an unprecedented impact on society over the last two decades. Compared to other disruptive technologies such as radio, telegraph, telephone, television, and the personal computer, the Internet has had one of the fastest adaptation times to reach the majority of the North American households. The outlook for new services over the Internet is tremendous, and these include telemedicine, telerobotic systems and Intelligent Highway System. However, there are significant unsolved technical problems to be addressed. In 2007, the US National Science Foundation (NSF) has embarked in a new program called 'Global Environment for Network Innovations' (GENI), with the goal of addressing the problems that have 'plagued the Internet' since its inception. These problems include Quality of Service, security, reliability, and the seemless integration of wireless technologies. These problems are so complex that the GENI program is open to a 'clean-slate' approach in which the entire Internet may be re-designed from ground up. This applicant has developed a new scheduling algorithm. The algorithm can achieve near-perfect Quality of Service for statically provisioned multimedia traffic flows in general packet-switched networks such as the Internet, including the wired IP networks and infrastructure-based Wireless Mesh Networks. Funds are requested to explore this algorithm in more depth.
