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 Institution：University of Colorado，BoulderNets-Find：Radio Wormholes for Wireless Label Switch Mesh Network摘要该提案通过倡导建立在应用于光网络和有线网络的现有技术之上的新无线网络技术，解决了网状网络中的两个相关问题，即服务质量和流量工程。Mesh网络具有固定多点无线和自组织无线网络的特性，由于使用相同的频谱向站点和中继业务提供服务，因此通常比固定多点无线网络具有更低的吞吐量。总体而言，该提案涉及建造使用类似于光波长交换的“直通”交换的“无线电电路”。正交频分多址(OFDMA)用作底层物理层。单个网状网节点使用基于软件的无线电交换机实现，这允许快速转发传输的分组。最后，通用多协议标签交换(GMPLS)协议提供了一种管理方案，该研究将使Mesh和ad-hoc网络能够减少时延，提高吞吐量，实现服务质量能力，并为流量工程提供机制。无线分配是高速宽带接入的三种选择之一(另外两种是电缆调制解调器和DSL)。有效的网状分布网络将使无线成为宽带接入中一种具有竞争力的替代方案。它还将为灾难应对和恢复所需的快速部署网络提供可靠的网络技术。
