CIAN's New Testbed for Optical Aggregation Networking (TOAN)

新的光聚合网络测试平台（TOAN）增强了集成接入网络中心（CIAN）的创新能力，CIAN是一个工程研究中心，总部设在亚利桑那大学。该测试平台将协同补充其他CIAN合作大学的现有CIAN测试平台：哥伦比亚大学（“跨层优化”），在南加州大学（“光学数据内省”），以及在圣地亚哥的加州大学（“传输/处理”的主要测试平台和“数据中心”的计划扩展）。这些测试站点在各自的专业领域提供最先进的性能。新的灵活，多节点，异构流量“网络仿真器”将提供急需的面向网络的测试能力，为CIAN研究人员以及附属机构和行业在非常温和的成本。这一优势源于TOAN并非为超高传输速度和数据吞吐量而设计，而是用于演示和测试网络功能。它将专注于一个透明的聚合域，该域具有与住宅接入区和数据中心、相邻域以及核心/骨干网的接口。TOAN的智力优势在于其独特的方法，将目前分布在多个测试站点的功能（传输，处理，监测，控制）结合在一个统一的实验室风格，灵活，经济实惠和可管理的环境中。用于仿真多节点聚合网络的典型规范已经与CIAN工业分支机构合作导出，由此已经设置了相关目标，诸如异构传输介质上的6个节点/40 G数据速率/ 200 km链路长度/ 400 km环长度，需要自适应损伤补偿和/或损伤感知交换和路由。该平台将为CIAN研究人员以及附属机构和行业提供急需的面向网络的测试能力。 其中包括。损伤感知跨域流量工程和CIEN构建的设备的功能测试（关于可扩展性和网络稳定性），仅提及CIEN工业附属公司建议CIEN实现的几个功能。这种端到端的网络拓扑结构将允许在动态网络设置中实现损害补偿和切换的各种权衡的实验。拟议的新测试平台的更广泛的影响是三方面的：低层光网络平台的独特之处在于，它提供网络功能的仿真，而不是一个传输段的维度连接或仅各种处理任务的单独演示。(b)行业合作：应实地考察小组的要求，TOAN将进一步促进与工业界的合作（与工业界的贡献相匹配，表明有兴趣）。（c）本科教育：该试验台将用于建立一个为期一个学期的、图书馆式的“开放实验室”，以吸引即将入学的工程专业新生学习光通信，使他们熟悉先进的网络测试，并招募最优秀的学生作为未来CIAN的本科生研究助理。随着新的子系统的引入，测试台的功能将随着时间的推移而增加，从而提供更多的监控和控制各种网络配置的能力。 总的来说，该测试平台将加快CIAN为工业提供实用和有用的网络创新的能力。

The new Testbed for Optical Aggregation Networking(TOAN) augment the capacity for innovation of the Center for Integrated Access Networks (CIAN), an Engineering Research Center, headquartered at the University of Arizona This testbed will synergistically complement the existing CIAN testbeds at the other CIAN partner universities: Columbia University ("cross-layer optimization"), at the University of Southern California ("optical data introspection"), and at the University of California, San Diego (main testbed for "transmission/processing" and planned extension for "data centers"). These test sites offer cutting-edge performance in their respective areas of specialization. The new flexible, multi-node, and heterogeneous traffic "network emulator" will provide much-needed networking-oriented testing capabilities for CIAN researchers as well as for affiliated institutions and industry at very moderate cost. This benefit derives from the fact that TOAN is not designed for ultra-high transmission speed and data throughput, but rather for demonstrating and testing network functionalities. It will focus on a transparent aggregation domain with interfaces to residential access areas and data centers, to neighboring domains, and to the core/backbone. The intellectual merit of TOAN lies in its unique approach of combining functionalities (transmission, processing, monitoring, control) that are currently spread out over multiple test sites within a unified laboratory-style, flexible, affordable, and manageable setting. Typical specifications for emulating a multi-node aggregation network have been derived in collaboration with CIAN industrial affiliates, whereby relevant targets have been set such as 6 nodes / 40G data rates / 200 km link lengths / 400 km ring length over heterogeneous transmission media with the need for adaptive impairment compensation and/or impairment-aware switching and routing. This platform will provide much-needed networking-oriented testing capabilities for CIAN researchers as well as for affiliated institutions and industry. These include. impairment-aware cross-domain traffic engineering and functionality tests of CIAN-built devices with respect to cascadability and network stability, to mention only a few of the features that CIAN industrial affiliates have suggested CIAN implement. This end-to-end network topology will allow for experimentation with the various trade-offs in the implementation of impairment compensation and switching in dynamic network settings.The broader impact of the proposed new testbed is threefold: (a) Engineering research: The uniqueness of a lower-layer optical networking platform which provides emulation of network functionalities rather than the one-dimensional concatenation of transmission segments or the isolated demonstration of various processing tasks only. (b) Industry collaboration: As requested by the Site Visit Panel, TOAN will further stimulate collaboration with industry (matching industrial contributions demonstrate interest). (c)Undergraduate Education: the testbed will be utilized to establish a semester-long, seminar-style "open lab" in order to attract incoming engineering freshmen to optical communications, to familiarize them with advanced network tests, and to recruit the best students as future CIAN undergraduate research assistants. The functionality of the testbed will be increased over time as new subsystems are introduced giving more ability to monitor and control various network configurations. Overall, the testbed will speed up the capacity of CIAN to provide practical and useful networking innovations for industry.
