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

该发现基金将探索一种新的调度算法，该算法可以在通用分组交换网络和基于基础设施的无线网状网络（WMNs）上实现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，互联网是适应时间最快的技术之一，它进入了北美大多数家庭。互联网上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，仍有重大的未解决的技术问题需要解决。2007年，美国国家科学基金会（NSF）启动了一个名为“全球网络创新环境”（GENI）的新项目，其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、可靠性和无线技术的无缝集成。这些问题是如此复杂，以至于GENI计划对一种“从头开始”的方法持开放态度，在这种方法中，整个互联网可能会从头开始重新设计。申请人开发了一种新的调度算法。该算法对于Internet等一般分组交换网络（包括有线IP网络和基于基础设施的无线Mesh网络）中静态配置的多媒体流量流可以达到近乎完美的服务质量。请基金对该算法进行更深入的研究。

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.
