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：科罗拉多大学博尔德分校标题：NeTS-FIND：无线标签交换网状网络的无线电虫洞摘要该提案通过倡导一种新的无线网络技术，解决了网状网络、服务质量和流量工程中的两个相关问题它建立在应用于光纤和有线网络的现有技术之上。 网状网络具有固定多点无线网络和自组织无线网络的特性，通常比固定多点无线网络具有较低的吞吐量，因为相同的频谱用于向站点提供服务和中继流量。该提案旨在扩展和集成三种技术使网状网络更加有用。总体而言，该提案涉及构建使用类似于光学 lambda 开关的“直通”开关的“无线电电路”。 正交频率多址接入 (OFDMA) 作为底层 PHY 层。各个网状节点是使用基于软件的无线电交换机实现的，该交换机允许快速转发正在传输的数据包。最后，通用多协议标签交换（GMPLS）协议提供了一个管理平面。预计这项研究将使网状网络和自组织网络能够减少延迟、增加吞吐量、实现服务质量功能，并提供以下机制：交通工程。无线分布是高速宽带接入的三种选择之一（电缆调制解调器和 DSL 是另外两种）。有效的网状分布网络将使无线成为宽带接入领域具有竞争力的替代方案。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。
