项目摘要

Wavelength routed wide area networks will be an integral part of the future of all-optical network infrastructures. It is envisioned that these networks will act as the backbone that provides the interconnection for local area lightwave sub-networks attached to them. A significant amount of research effort has been devoted to the design and evaluation of wavelength routed architectures in recent years. However, the deployment of an infrastructure that will enable large scale interconnection of optical networks raises a number of fundamental and challenging problems that require novel and innovative solutions. The research plan outlined in this proposal identifies a number of significant but open problems arising in wavelength routed environments, and presents a comprehensive and novel approach to address them. The outcome of the proposed research will be an analytical framework that will permit the researchers to efficiently compute call blocking probabilities in wavelength routed networks, evaluate wavelength assignment policies and converter placement strategies, investigate routing algorithms for arbitrary network topologies, and study the performance of multicast calls. One of the main objectives of the work is to identify potential fairness problems that may arise in such an environment, and to employ a combination of routing , converter placement, and wavelength assignment strategies to alleviate these problems and ensure fair treatment for all calls.

波长路由广域网将是未来全光网络基础设施的重要组成部分。按照设想，这些网络将充当骨干，为附着在它们上面的局部光波子网络提供互连。近年来，人们对波长路由架构的设计和评估进行了大量的研究。然而，部署能够实现大规模光网络互连的基础设施提出了许多基本和具有挑战性的问题，这些问题需要新颖和创新的解决方案。本提案中概述的研究计划确定了波长路由环境中出现的一些重要但开放的问题，并提出了一种全面而新颖的方法来解决这些问题。提出的研究结果将是一个分析框架，允许研究人员有效地计算波长路由网络中的呼叫阻塞概率，评估波长分配策略和转换器放置策略，研究任意网络拓扑的路由算法，并研究多播呼叫的性能。这项工作的主要目标之一是确定在这种环境中可能出现的潜在公平性问题，并采用路由、转换器放置和波长分配策略的组合来缓解这些问题，并确保对所有呼叫的公平对待。
