Software-defined networking (SDN) is a promising paradigm that has the potential to enable Internet Service Providers (ISPs) to achieve a high level of network automation and therefore significant cost savings. Indeed software-defined wide area networks (SD-WANs) are emerging in industry and are projected to account for 25 percent of WAN traffic by 2021. However, many challenges remain. The networks of large ISPs such as AT&T are complex, and most Internet traffic traverses multiple network domains. It is highly desirable, then, to extend the software control paradigm to enable fast, efficient, cost effective end-to-end provisioning of services and resources over heterogeneous, multi-domain networks in an integrated and unified way. The goal of this project is to address research challenges in this area, leveraging SDN and investigating novel strategies for expediting efficient data transfer across the fiber optic backbone networks underlying the Internet. A unified network architecture for a software defined optical network (SDON) will be developed that features: (1) End-to-end provisioning of services, and (2) Expediting data transfers over multiple domains that use heterogeneous transport layer technologies using inter-domain tunnels. SDONs will usher in virtualization and intelligence as the new features of future networks. The project will explore different strategies for dynamic resource allocation including the creation and use of virtual transport links (VTL) and associated bandwidth-on-demand (BoD) techniques. The project will also explore a Resource Delayed Release (RDR) strategy to reduce the dynamic service provisioning time and multi-domain tunnels to expedite data transfers in multi-layer networks involving Optical Transport Network (OTN), Wavelength Division Multiplexing (WDM) and Elastic Optical Networking (EON) layers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

软件定义网络（SDN）是一种有前途的范例，有可能使互联网服务提供商（ISP）实现高水平的网络自动化，从而节省大量成本。事实上，软件定义广域网（SD-WAN）正在工业中兴起，预计到2021年将占WAN流量的25%。 然而，仍然存在许多挑战。大型ISP（如AT T）的网络非常复杂，大多数互联网流量都会穿越多个网络域。 因此，非常期望扩展软件控制范例以使得能够以集成和统一的方式在异构的多域网络上快速、高效、成本有效地端到端供应服务和资源。 该项目的目标是解决这一领域的研究挑战，利用SDN并研究新的策略，以加快互联网底层光纤骨干网络的高效数据传输。 将开发用于软件定义光网络（SDON）的统一网络架构，其特征在于：（1）端到端的服务供应，以及（2）使用域间隧道在使用异构传输层技术的多个域上加速数据传输。SDON将迎来虚拟化和智能化作为未来网络的新特征。该项目将探讨动态资源分配的不同战略，包括建立和使用虚拟传输链路和相关的按需带宽技术。该项目还将探索资源延迟释放（RDR）策略，以减少动态服务提供时间和多域隧道，以加快涉及光传输网络（OTN）的多层网络中的数据传输，波分复用（WDM）和弹性光网络（EON）该奖项反映了NSF的法定使命，并已被认为是值得通过评估使用基金会的智力价值和更广泛的支持影响审查标准。
