Future communication networks are envisioned be dynamic reconfigurable at the physical, label and routing layers forming a multiple layer communication infrastructure. In the resulting hierarchical structure each layer is a network on its own, having the flexibility to change the formation dynamically. There are also structural dependencies due to the multilayer infrastructure. For example, a link failure at a lower layer can impact multiple links at an upper layer. With dynamic changes in traffic demand, reconfigurability, and structural dependencies, future multilayer networks present new design challenges. In this project, future multilayer network design is addressed by considering routing properties of different layer networks, layer dependencies, virtualization, topological reconfigurability, and resiliency. For this, new optimization models are developed. As the problems can be large due to interdependencies, new design algorithms are developed that exploit the special structure of the problems. The exploration of multilayer networks with emerging technological possibilities leads to key insights that would benefit future networks in terms of efficient and robust network design, deployment, and operations. Expected results include new design models and algorithms. Studies conducted will provide deeper understanding of the overall system dynamics in terms of interdependencies in layers and trade-offs on functionalities to be invoked in different layers. All research results will be made available to the scientific community.

未来的通信网络被设想为在物理层、标签层和路由层处可动态重新配置，从而形成多层通信基础设施。在由此产生的分层结构中，每一层都是一个独立的网络，具有动态改变队形的灵活性。由于多层基础设施，还存在结构依赖性。例如，较低层处的链路故障可能影响较高层处的多个链路。随着流量需求、可重构性和结构依赖性的动态变化，未来的多层网络提出了新的设计挑战。 在这个项目中，未来的多层网络设计是通过考虑不同层网络的路由属性，层依赖性，虚拟化，拓扑可重构性和弹性。为此，开发了新的优化模型。由于问题可能是大的，由于相互依赖性，新的设计算法开发，利用特殊结构的问题。 对具有新兴技术可能性的多层网络的探索带来了关键的见解，这些见解将有利于未来网络的高效和强大的网络设计，部署和运营。 预期成果包括新的设计模型和算法。所进行的研究将从各层之间的相互依存关系和在不同层调用的功能的权衡方面，更深入地了解整个系统的动态。所有研究成果将提供给科学界。
