IHCS: Cyber Systems: DWDM Multi-Mode Switching for Telesurgery and Heterogeneous Applications

本研究的目标是开发一种新型的路由器体系结构，该体系结构能够经济高效地支持大量密集波分复用(DWDM)信道，同时满足不同应用的需求。该方法是设计一个能够同时支持电子分组交换、光电路交换和光突发交换的集成多模交换路由器平台。使用这种多模式交换方法，每个波长通道可以单独重新配置为不同的交换模式。每个应用程序或应用程序中的每种消息类型都可以选择最合适的交换模式。就智能优点而言，该项目提供了一种通过维护相对较少的昂贵电子交换端口来实现路由器系统成本效益扩展的方法。对多模式交换路由器节点内不同交换模式之间的相互作用的评估提供了对性能和成本权衡的洞察。集成多模式调度方案的发展为管理不同交换模式之间共享的系统资源提供了一种统一的方法，从更广泛的影响来看，该方法具有促进包括远程医疗和远程外科在内的各种异质网络应用的潜力，这是本研究明确考虑的。远程医疗和远程外科使医疗专家和资源能够远程共享，并提供了改变提供高质量医疗服务的方式的机会。该项目及其相关的网络试验台为研究生和本科生，特别是妇女和来自其他代表性不足群体的学生提供了培训机会。高中生在首席研究员的研究实验室从事相关项目的工作，这有可能吸引这些学生进入工程学。

The objective of this research is to develop a novel router architecture that can cost effectively support a large number of dense wavelength division multiplexing (DWDM) channels while meeting the needs of a diverse set of applications. The approach is to design an integrated multi-mode switching router platform that can concurrently support electronic packet switching, optical circuit switching, and optical burst switching. With this multi-mode switching approach, each wavelength channel can be individually reconfigured to a different switching mode. Each application or each type of message within an application can choose the most appropriate switching mode.With respect to intellectual merit, the project provides an approach for cost effective scaling of router systems by maintaining a relatively small number of expensive electronic switching ports. The evaluation of the interplay among different switching modes within the multi-mode switching router node provides insights into performance and cost tradeoffs. The development of integrated multi-mode scheduling schemes provides a unified approach to manage system resources shared among different switching modes.With respect to broader impacts, the proposed approach has the potential to facilitate a variety of heterogeneous networked applications, including telemedicine and telesurgery which are explicitly considered in this research. Telemedicine and telesurgery allow medical experts and resources to be shared remotely and offer the opportunity to change the how quality medical services can be delivered. This project and its related network test bed provide training opportunities to graduate and undergraduate students, especially women and students from other underrepresented groups. High school students work on related projects in the principal investigator's research laboratory and this has the potential to attract these students to engineering.
