Current optical networks are mostly statically provisioned at the lowest optical layer. Moving the communications infrastructure to a dynamically provisioned optical infrastructure will allow on-demand provisioning of high-bandwidth circuits in support of science, commerce, media, and national security. Dynamic optical networks will contribute to bridging the digital divide and supporting bandwidth intensive transformative applications such as 3-D video for telepresence in education and telemedicine. The physical layer components of such a network are emerging from research on dynamic optical devices and technologies and offer unique opportunities. However, controlling dynamic optical networks while considering the physical layer Quality of Transmission and the higher layer requirements poses major challenges due to both the interactions of multiple light paths sharing the same fiber and the challenges of adapting to multiple fiber types and physical infrastructures with varying impairments.This project contributes to the deployment of dynamic optical networks by developing cross-layered network control algorithms for wide-area and data center optical networks. The algorithms rely on the capabilities of real-time optical performance monitors (OPMs) and allow efficient use of the optical resources through dynamic network configuration, regeneration, and power, bandwidth, and modulation control. Since the effects of dynamic operation in wide-area networks are analytically intractable, the project develops an optimization framework that, rather than employing theoretical models and analytical solutions, uses direct input from OPM measurements. For data center networks, the project is designing network configuration schemes that allow physical support of various *-cast (unicast, anycast, multicast, etc.) higher layer requirements. This project includes engaging diverse student populations in the cross-layered research and outreach activities to the Harlem community.

当前的光网络主要在最低的光学层上静态提供。 将通信基础架构转移到动态提供的光学基础设施中，将允许对高带宽电路进行按需提供，以支持科学，商业，媒体和国家安全。 动态光网络将有助于桥接数字鸿沟并支持带宽密集的变革性应用，例如3-D视频用于教育和远程医疗。 这种网络的物理层成分来自对动态光学设备和技术的研究，并提供了独特的机会。但是，在考虑传输的物理层质量和较高层要求的同时，控制动态光网络，这在多种光路径的相互作用之间构成了重大挑战，这些光路相互作用共享相同的光纤，以及适应多个光纤类型和物理基础架构的挑战，以及与各种障碍的物理基础架构。这些项目可以通过开发跨界网络的方式来开发盘旋网络，从而有助于开发盘旋网络。该算法依赖于实时光学性能监视器（OPM）的功能，并通过动态网络配置，再生以及功率，带宽和调制控制来有效利用光学资源。 由于在大区域网络中动态操作的影响在分析上是棘手的，因此该项目开发了一个优化框架，而不是使用理论模型和分析解决方案，而是使用OPM测量值的直接输入。对于数据中心网络，该项目正在设计网络配置方案，该方案允许对各种 *cast（Unicast，Anycast，多播等）进行物理支持。该项目包括吸引多元化的学生群体参与跨层次的研究和向哈林社区的外展活动。
