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

提案编号：0627172 PI：Dirk Grunwald机构：科罗拉多大学，博尔德标题：NetS-FIND：无线标签交换网状网络的无线电虫洞摘要该建议通过倡导一种新的无线网络技术来解决网状网络中的两个相关问题，即服务质量和流量工程，该技术建立在应用于光和有线网络的现有技术上。 Mesh网络具有固定多点无线网络和ad hoc无线网络的共同特性，但由于使用相同的频谱来向站点提供服务和中继流量，因此其吞吐量通常低于固定多点无线网络。总的来说，该提案涉及建立“无线电电路”，使用类似于光λ交换的“直通”交换。 正交频率多址（OFDMA）用作底层PHY层。单个网格节点使用基于软件的无线电交换机来实现，该交换机允许快速转发过境数据包。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和自组织网络，以减少延迟，增加吞吐量和实现服务质量的能力，以及提供机制，流量工程。无线分发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的一种有竞争力的选择。它还将为救灾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.
