The dramatic increase in throughput demands on transport systems has propelled the development of all-optical networks. These networks can provide tremendous capacity when they are designed with their own limitations in mind, such as coarse wavelength granularity and physical impairments. In this research we consider the holistic design of optical networks that include the interdependence of three network layers: the traffic grooming layer, the lightpath management layer, and the physical fiber layer.The network is first viewed from the top-down, where sub-wavelength circuit requests arrive with specific quality of service requirements. Current traffic grooming approaches are altered to incorporate their dependence on the lightpath management and physical layer constraints.The system is then examined from the bottom-up, so that the quality of transmission and efficiency of resource utilization can be optimized as the higher layer protocols evolve. Total capacity is measured from an information theoretic view point and system optimization uses ideas from game theory.The results of the research will be practical algorithms for improved capacity and survivability of future optical networks as well as providing a quantitative proof of their superiority. The enhancement of network capability will help satisfy our society?s ever-increasing need for information. It encourages the development of applications that require significant bandwidth. It also stimulates cross-fertilization of ideas from the two fields of networking and communications. The algorithms and software will be made publicly available via a web-site. The research enhances the education of the diverse group of graduate and undergraduate students participating in it.

对传输系统吞吐量需求的急剧增加推动了全光网络的发展。当这些网络在设计时考虑到其自身的限制（例如粗波长粒度和物理损伤）时，它们可以提供巨大的容量。在这项研究中，我们考虑的光网络的整体设计，包括三个网络层的相互依赖性：业务疏导层，光路管理层，和物理光纤层。现有的流量疏导方法被改变，以纳入他们的依赖光路管理和物理层的约束条件。然后，系统进行检查，从下至上，使传输质量和资源利用效率可以优化的高层协议的演变。从信息论的角度对总容量进行了度量，系统优化采用了博弈论的思想，研究结果将成为未来光网络提高容量和生存性的实用算法，并为它们的优越性提供定量的证明。网络能力的提高将有助于满足我们的社会？人们对信息的需求不断增长。它鼓励开发需要大量带宽的应用程序。它还促进了网络和通信两个领域的思想交流。这些算法和软件将通过一个网站公开提供。这项研究加强了对参与研究生和本科生的不同群体的教育。
