NeTS-FIND: Radio Wormholes for Wireless Label Switched Mesh Networks

提案编号：0627172PI: Dirk Grunwald机构：University of Colorado， boulder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，建立在现有的应用于光和有线网络的技术基础上，解决了网状网络中两个相关的问题，即服务质量和流量工程。Mesh网络共享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的吞吐量低，因为使用相同的频谱向站点提供服务和中继流量。该提案旨在扩展和整合三种技术，以使网状网络更有用。总的来说，这个提议包括建造“无线电电路”，使用类似于光lambda开关的“直通”开关。正交频多址（OFDMA）作为底层物理层。单个网格节点使用基于软件的无线电交换机实现，允许传输数据包快速转发。最后，通用多协议标签交换（GMPLS）协议提供了一个管理平面。预计该研究将使网状和自组织网络能够减少延迟，提高吞吐量，提高服务质量，并为流量工程提供机制。无线分布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）。有效的网状分配网络将使无线成为宽带接入的一个有竞争力的选择。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。

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.
