In this proposal, we propose to develop a Cyberinfrastructure for Reconfigurable Optical Networks (CRON). With supercomputing facilities and storage resources geographically dispersed across the US and around the globe, the success of scientific applications and collaborations relies increasingly on high-speed optical networks. The development and deployment of national and international optical networks and regional networks make it possible for more scientists, research and educational institutes to connect and collaborate at previously unachievable levels.However, there is a critical gap between the research projects and the deployed high speed networks, caused by the following problems: (1) Limited physical resource ? e.g., the expensive resource of the LONI network has limitations on the number of simultaneous users, and there are many research and/or educational institutions in Louisiana that cannot access the networks due to the last mile problem.; (2) Unmodifiable environment - because the currently deployed networks are used for production as well as research, individual users cannot impose on other users by modifying environmental parameters, such as network protocol stacks and operating systems; and (3) Partial environment ? applications or protocols developed for one specific high speed network should work correctly over all kinds of different networks, irrespective of different network bandwidths and delays. However, each deployed physical network has one physical characteristic, such as bandwidth and delay.The goal of this project is to bridge the gap between physical networks and research by developing a virtual networking and computing cyberinfrastructure, CRON, that provides integrated and automated access to diverse networking environments. To provide the virtual environments, CRON consists of two components: hardwares including a switch, optical fibers, network emulators and softwares automatically reconfiguring the hardwares based on users? demands. CRON resolves the critical issues by achieving three key objectives: (i) Unlimited virtual networking resource CRON will enable researchers to explore new network technologies and rapidly assess their impact on applications irrespective of physical limitation and allow educators to introduce the state-of-art networking environment to students who cannot access those physical networks. (ii) Reconfigurability CRON will allow researchers and educators to modify the virtual environments without interfering with others who share CRON. (iii) Complete environment CRON will provide all kinds of networking environments, including regional networks and global transoceanic optical networks.

在本提案中，我们建议开发可重构光网络（CRON）的网络基础设施。由于超级计算设施和存储资源在地理上分散在美国和地球仪各地，科学应用和协作的成功越来越依赖于高速光网络。国家和国际光网络以及区域网络的发展和部署，使更多的科学家、研究和教育机构能够以以前无法实现的水平进行连接和合作，但研究项目与已部署的高速网络之间存在着严重差距，原因是以下问题：（1）物理资源有限？例如，在一个实施例中，LONI网络昂贵的资源限制了同时使用的用户数量，并且路易斯安那州的许多研究和/或教育机构由于最后一英里问题而不能访问网络。(2)不可修改的环境-由于目前部署的网络用于生产以及研究，个人用户不能通过修改环境参数，如网络协议栈和操作系统强加给其他用户;（3）部分环境？为一个特定的高速网络开发的应用或协议应该在所有种类的不同网络上正确地工作，而不管不同的网络带宽和延迟。然而，每个部署的物理网络都有一个物理特性，如带宽和延迟。本项目的目标是通过开发一个虚拟网络和计算网络基础设施CRON，提供集成和自动访问不同的网络环境，以弥合物理网络和研究之间的差距。为了提供虚拟环境，CRON由两部分组成：硬件包括交换机，光纤，网络仿真器和软件自动重新配置硬件的基础上用户？要求。CRON通过实现三个关键目标来解决关键问题：（i）无限的虚拟网络资源CRON将使研究人员能够探索新的网络技术，并迅速评估其对应用程序的影响，而不受物理限制，并允许教育工作者向无法访问这些物理网络的学生介绍最先进的网络环境。(ii)可重构CRON将允许研究人员和教育工作者修改虚拟环境，而不会干扰共享CRON的其他人。(iii)CRON将提供各种组网环境，包括区域网络和全球跨洋光网络。
