This project will create and demonstrate experimentally key features of a new optical network architecture, 'HyperFlow' which is a hybrid future Internet architecture that include key designs for both hardware and algorithms. The network is designed to be dynamic (both agile and adaptive), and significantly more cost effective and power efficient for future growth in data volumes and number of users. The architecture relies on a novel optical network infrastructure comprising new transport mechanisms and a new comprehensive control mechanism including the physical hardware, algorithms and applications. Between locations that exchange large volumes of data - say, Los Angeles and New York City ? the flow switching mechanism of HyperFlow would establish a dedicated path across the network. The allotment of bandwidth would change constantly. As traffic between New York and Los Angeles increased, new, dedicated wavelengths would be recruited to handle it; as the traffic tailed off, the wavelengths would be relinquished. The goal is to develop network management protocols that can perform new session allocations in a matter of sub-seconds. HyperFlow can easily increase the data rates of optical networks 100-fold with the new network management scheme to be addressed in this program, with corresponding decrease in cost per bit and power consumption as well.Intellectual Merit: HyperFlow creates a complete hybrid flow/IP network architecture spanning local to wide areas, sharing the same unified control plane. The network provides both guaranteed end-to-end multi-Gbps flow service and conventional Internet Packet services throughout the network down to individual users. To achieve that goal, HyperFlow includes novel access and long haul core network technologies designed to support end-to-end flows as well as conventional IP network services. This approach achieves a breakthrough with respect to previous approaches by providing both services end-to-end with a unified control plane. HyperFlow includes major innovations based on highly efficient, agile and control of pools of shared tunable lasers and passive optical devices, a fast MAC, partitioned routing strategy and a new transport protocol for flows. Broader impact: If successful the proposed HyperFlow technology will have a profound influence on the way the future Internet is designed and perceived by the society, as the new on-demand cost-effective gigabit service will enable applications that are hard or costly to support today with existing broadband access, such as instantly-available 3D distributed virtual-reality systems, cloud computing and instant file transfer services including telemedicine, education, 3D movies, concerts, sporting events, and government services. The concept of the new Hyperflow development will be brought into industry forums such as IETF/IRTF during the project, so that the best minds of the industry can be leveraged for conceptual validation.

该项目将创建并通过实验演示新光网络架构“HyperFlow”的关键功能，这是一种混合的未来互联网架构，包括硬件和算法的关键设计。该网络被设计为动态的（敏捷和自适应），并且对于未来数据量和用户数量的增长而言，显着更具成本效益和能效。该架构依赖于一种新颖的光网络基础设施，包括新的传输机制和新的综合控制机制，包括物理硬件、算法和应用程序。在交换大量数据的地点之间 - 例如洛杉矶和纽约市？ HyperFlow的流交换机制将在网络中建立一条专用路径。带宽的分配会不断变化。随着纽约和洛杉矶之间的流量增加，将招募新的专用波长来处理它；随着流量的减少，波长将被放弃。目标是开发可以在亚秒内执行新会话分配的网络管理协议。通过本计划中要解决的新网络管理方案，HyperFlow 可以轻松地将光网络的数据速率提高 100 倍，同时每比特成本和功耗也相应降低。 智力优点：HyperFlow 创建了完整的混合流/IP网络架构跨越本地到广域，共享相同的统一控制平面。该网络提供有保证的端到端多 Gbps 流服务和整个网络中直至个人用户的传统互联网分组服务。为了实现这一目标，HyperFlow 包括新颖的接入和长途核心网络技术，旨在支持端到端流以及传统的 IP 网络服务。这种方法通过为两种服务提供端到端的统一控制平面，相对于以前的方法实现了突破。 HyperFlow 包括基于共享可调谐激光器和无源光学设备池的高效、敏捷和控制、快速 MAC、分区路由策略和新的流传输协议的重大创新。更广泛的影响：如果成功，拟议的 HyperFlow 技术将对未来互联网的设计和社会感知方式产生深远影响，因为新的按需经济高效的千兆位服务将使当今难以支持或成本高昂的应用程序成为可能现有的宽带接入，例如即时可用的 3D 分布式虚拟现实系统、云计算和即时文件传输服务，包括远程医疗、教育、3D 电影、音乐会、体育赛事和政府服务。新的Hyperflow开发概念将在项目期间引入IETF/IRTF等行业论坛，以便利用行业最优秀的人才进行概念验证。
