NeTS:Small: Multilayer Reconfigurable Network Design and Optimization

未来的通信网络被设想为在物理层、标签层和路由层可动态重新配置，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，还存在结构依赖关系。例如，较低层的链路故障可能会影响较高层的多条链路。随着流量需求、可重构性和结构相关性的动态变化，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将考虑不同层网络的路由属性、层依赖、虚拟化、拓扑可重构性和弹性。为此，开发了新的优化模型。由于问题可能由于相互依赖而变得很大，因此开发了利用问题的特殊结构的新的设计算法。对具有新兴技术可能性的多层网络的探索将带来关键的见解，这些见解将在高效、可靠的网络设计、部署和运营方面惠及未来的网络。预期结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之间的权衡方面，更深入地了解整个系统动态。所有研究成果都将提供给科学界。

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.
