CAREER: Dynamic Multi-Domain/Multi-Granularity Network Provisioning

近年来，高速传输网络技术得到了前所未有的部署，特别是基于先进的下一代同步光网络(SONET)和波分复用。虽然这些特定技术的相关运营商配置方法已经得到了很好的研究，但更广泛的应用(网格计算、存储网络、虚拟专用网络)的出现正在推动对跨多个网域和粒度层的动态服务配置的需求。这份职业计划专注于由数百个节点组成的异质、高性能、高带宽、多域网络领域的研究，并应对动态连接需求，称为“按需带宽”服务。主要工作包括可扩展的域间路由、路径选择和流量疏导、服务可生存性以及高性能网络基础设施扩展。总体而言，该项目预计将为大规模、分布式、多域、电路交换基础设施的运营提供基本的见解。因此，它将有助于加快发展强大的下一代网络基础设施，从而促进各种新服务和应用的出现。

The recent years have seen unprecedented deployments of high-speed transport networking technologies, particularly based on advanced, next-generation synchronous optical networks (SONET) and wavelength division multiplexing. While related carrier provisioning methods for these specific technologies have been well-studied, the emergence of more expansive applications-grid computing, storage networking, virtual private networks-is driving the need for dynamic service provisioning across multiple network domains and granularity layers. This CAREER proposal focuses on research in the area of heterogeneous, high-performance, high-bandwidth, multi-domain networks comprising hundreds of nodes and fielding dynamic connection demands, refereed to as "Bandwidth-on-Demand" Services. The key efforts include scalable inter-domain routing, path selection and traffic grooming, service survivability, and high-performance network infrastructure expansion. Overall, this project is expected to yield fundamental insights into the operation of large-scale, distributed, multi-domain, circuit-switched infrastructures. As such, it will help accelerating the development of robust next-generation cyber-infrastructure, thereby facilitating the emergence of a wide range of new services and applications.
