NeTS-NBD: Physically Aware Agile Networking

物理感知敏捷网络PI：Brendan Mumey该研究项目考虑了敏捷的基于约束的路由和波长分配（RWA）策略，以减轻影响下一代全光网络端到端性能的物理层损伤。 正在开发的RWA方法考虑到不断变化的流量模式、资源可用性和瞬态条件下底层物理层的行为，以最大限度地减少损害并确保达到服务质量（QoS）要求。 影响端到端路径性能的物理层网络损伤包括开关瞬变、放大器增益波动和信道串扰。 网络流量的时间和地理变化也会影响网络性能。 正在设计一个用于研究这种损害和流量变化的累积效应的一般框架，并使用蒙大拿州立大学光网络试验台进行。 这项工作需要结合建模、仿真和验证步骤。 基于这一新的框架，国家的最先进的物理感知RWA算法正在设计，实施和测试。更广泛的影响：这项研究的成果将成为未来的网络基础设施的重要组成部分，通过探索方法来管理底层网络，是符合新的应用驱动的网络需求。该项目将整合电气和计算机工程与计算机科学的教学和研究活动，汇集来自两个学科的教师和学生，以解决跨越两个学科的系统级设计问题。项目团队将通过跨学科的高级设计课程和个人研究项目，让本科生参与研究。 与少数民族的联系将通过密歇根州立大学的完善计划来促进，这些计划使美国原住民参与科学和工程。

Physically Aware Agile NetworkingPI: Brendan MumeyThis research project considers agile constraint-based routing and wavelength assignment (RWA) strategies to mitigate physical layer impairments that affect the end-to-end performance of next generation all-optical networks. The RWA methods being developed take into account changing traffic patterns, resource availability, and the behavior of the underlying physical layer under transient conditions to minimize impairments and assure that Quality of Service (QoS) requirements are achieved. Physical layer network impairments that affect end-to-end path performance include switching transients, amplifier gain fluctuations, and channel cross talk. Temporal and geographic variations in network traffic can also affect network performance. A general framework for studying the cumulative effects of such impairments and traffic variations is being designed and conducted using the Montana State University optical network testbed. This work requires a combination of modeling, simulation and validation steps. Based on this new framework, state-of-the-art physically aware RWA algorithms are being designed, implemented and tested.Broader Impact:The outcomes of this research will become an important component for future cyber infrastructure by exploring methods to manage the underlying network that are consistent with the new application-driven network demands. This project will integrate teaching and research activities in electrical and computer engineering with computer science, bringing together faculty and students from both disciplines to address system-level design issues spanning both disciplines. The project team will engage undergraduate students in the research through interdisciplinary senior design courses and individual research projects. Outreach to minorities will be facilitated through the well-established programs at MSU that engage Native Americans in the sciences and engineering.
