项目摘要

Recent advances in optical wavelength division multiplexing (WDM) and optical switching have enabled the development of next generation computer networks, to operate at several Terabits per second. A side impact of this development is that fault tolerance has become even more important, since a single failure may now result in much greater loss of information. The proposed research will investigate critical problems in the design of survivable optical wavelength division multiplexed (WDM) networks that are based on mesh topology. The novelty of the proposed work is two-fold: first is the consideration of wavelength-sharing wavelength routed networks (WRWS), where multiple individual sessions may share a wavelength, and the second is consideration of multiple simultaneous link failures. The goal is to provide reliable connections, based on deterministic and probabilistic requirements, to the clients using the network. This topic constitutes an important component of the nation's critical infrastructure protection, given that optical WDM networks are fast becoming part of the high-speed national wide-area backbone infrastructure. The underlying goal is to obtain practical and tractable optimal and near-optimal solutions for networks with a large number of nodes (50 - 100), with several fibers per link and more than 100 wavelengths per fiber; an additional objective is achieving sub-millisecond restoration times, compared to the few-seconds solutions of today. The proposed research will address the performance comparison and cost-benefit tradeoffs of wavelength-sharing and optical burst switching (OBS) mechanisms.
光波分复用(WDM)和光交换的最新进展使得下一代计算机网络的发展成为可能,以每秒几兆比特的速度运行。这种发展的一个副作用是容错变得更加重要,因为单个故障现在可能导致更大的信息丢失。本研究将探讨在网状拓扑结构的基础上设计可生存的光波分复用(WDM)网络的关键问题。所提出的工作的新奇是双重的:首先是考虑波长共享波长路由网络(WRWS),其中多个单独的会话可以共享一个波长,第二个是考虑多个同时链路故障。目标是根据确定性和概率性要求,向使用网络的客户端提供可靠的连接。鉴于WDM光网络正迅速成为高速国家广域骨干基础设施的一部分,该主题构成了国家关键基础设施保护的重要组成部分。其基本目标是为具有大量节点(50 - 100)的网络获得实用且易于处理的最佳和接近最佳的解决方案,每个链路有几根光纤,每根光纤有100多个波长;另一个目标是实现亚毫秒级的恢复时间,与今天的几秒解决方案相比。本研究将探讨波长分享与光突发交换机制之效能比较与成本效益权衡。
