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.

该项目将创建和实验演示一个新的光网络架构的关键功能，“HyperFlow”，这是一个混合的未来互联网架构，包括硬件和算法的关键设计。该网络设计为动态（灵活和自适应），并且在未来数据量和用户数量的增长中具有更高的成本效益和功率效率。该架构依赖于一种新型的光网络基础设施，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--比如说，洛杉矶和纽约市？HyperFlow的流交换机制将在网络上建立专用路径。带宽的分配会不断变化。随着纽约和洛杉矶之间的通信量增加，新的专用波长将被招募来处理它;随着通信量的减少，波长将被放弃。目标是开发网络管理协议，可以在几秒钟内执行新的会话分配。HyperFlow可以轻松地将光网络的数据传输速率提高100倍，同时降低每比特的成本和功耗。智能优势：HyperFlow创建了一个完整的混合流/IP网络架构，从本地到广域，共享同一个统一的控制平面。该网络在整个网络中向个人用户提供有保证的端到端多Gbps流服务和传统的互联网分组服务。为了实现这一目标，HyperFlow包括新的接入和长距离核心网络技术，旨在支持端到端流以及传统的IP网络服务。这种方法通过向两种服务端到端提供统一的控制平面，实现了相对于先前方法的突破。HyperFlow包括基于高效、敏捷和控制共享可调谐激光器和无源光学设备池的重大创新，快速MAC，分区路由策略和新的流传输协议。更广泛的影响：如果成功，HyperFlow技术将对未来互联网的设计和社会感知产生深远的影响，因为新的按需成本效益千兆服务将使现有宽带接入难以或昂贵的应用程序能够支持，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。在项目期间，新的Hyperflow开发概念将被带到IETF/IRTF等行业论坛，以便行业最优秀的人才可以用于概念验证。
