NeTS: Small: Collaborative Research: Holistic and Integrated Design of Layered Optical Networks

传输系统吞吐量需求的急剧增长推动了全光网络的发展。如果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，则它们可以提供巨大的容量。在本研究中，我们考虑了光网络的整体设计，包括业务疏导层、光路管理层和物理光纤层这三个网络层之间的相互依赖关系。网络首先是自上而下的，其中亚波长电路请求到达时具有特定的服务质量要求。对现有的流量疏导方法进行了改进，将其对光路管理和物理层约束的依赖纳入其中，然后对系统进行自下而上的检查，以便随着高层协议的发展而优化传输质量和资源利用效率。总容量是从信息论的角度来衡量的，系统优化使用了博弈论的思想。研究结果将为提高未来光网络的容量和生存性提供实用的算法，并为其优越性提供定量的证明。网络能力的增强将有助于满足我们的社会？S对信息的需求日益增长。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这两个领域的思想的交叉融合。这些算法和软件将通过一个网站公开提供。这项研究加强了参与其中的不同群体的研究生和本科生的教育。

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.
