Proposal Number: 0627172PI: Dirk Grunwald Institution: University of Colorado, BoulderTitle: NeTS-FIND: Radio Wormholes for Wireless Label Switched Mesh NetworksAbstractThis proposal addresses two related problems in mesh networking, quality of service and traffic engineering, by advocating a new wireless network technology that builds on existing technologies applied to optical and wired networks. Mesh networks, which share properties of fixed multipoint wireless and ad hoc wireless networks, typically have lower throughput than fixed multipoint wireless networks because the same spectrum is used to deliver service to stations and relay traffic.This proposal seeks to extend and integrate three technologies to make mesh networks more useful. Overall, the proposal involves building "radio circuits" that use "cut through" switching similar to optical lambda switching. Orthogonal frequency multiple access (OFDMA) serves as the underlying PHY layer. Individual mesh nodes are implemented using a software-based radio switch, which allows transiting packets to be rapidly forwarded. Lastly, the Generalized Multi-Protocol Label-Switching (GMPLS) protocol provides a management plane.It is expected that this research will enable mesh and ad hoc networks to decrease latency, increase throughput and enable quality of service capabilities as well as provide mechanisms for traffic engineering. Wireless distribution is one of the three options for high speed broadband access (with cable modem and DSL being the other two). Effective mesh distribution networks will enable wireless to be a competitive alternative in broadband access. It will also provide a reliable network technology for rapidly deployable networks needed for disaster response and recovery.

提案编号：0627172PI：Dirk Grunwald机构：科罗拉多大学，博尔迪特尔大学：网络 - 芬德：无线标签的无线电虫洞切换网状网络网络萨特萨尔特斯（Sabtractrestractrestrats）提案中的两个相关问题，在网络网络，服务质量和交通网络上，通过对现有技术进行构建的新网络质量和交通技术，以构建现有技术。 共享固定多点无线和无线无线网络的属性的网格网络通常比固定多点无线网络具有较低的吞吐量，因为相同的频谱可用于向电台提供服务和中继流量。此提案旨在扩展和集成三个技术以使网格网络更有用。总体而言，该提案涉及构建使用“通过”切换的“无线电电路”，类似于光学Lambda开关。 正交频率多访问（OFDMA）用作基础PHY层。使用基于软件的无线电开关实现各个网格节点，该开关允许迅速转发传输数据包。最后，广义的多协议标签开关（GMPLS）协议提供了管理平面。预计这项研究将使网格和临时网络能够降低潜伏期，提高吞吐量和启用服务能力质量，并提供交通工程的机制。无线分布是高速宽带访问的三个选项之一（电缆调制解调器和DSL是其他两个选项）。有效的网格分销网络将使无线成为宽带访问中的竞争选择。它还将为灾难响应和恢复所需的快速部署网络提供可靠的网络技术。
