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

新的光聚合网络测试床(TOAN)增强了总部位于亚利桑那大学的工程研究中心综合接入网络中心(CIAN)的创新能力。该测试床将协同补充其他CIAN合作伙伴大学的现有CIAN测试床：哥伦比亚大学(“跨层优化”)、南加州大学(“光数据自省”)和加州大学圣地亚哥分校(“传输/处理”的主要测试床和计划中的“数据中心”扩展)。这些测试站点在各自的专业领域提供最先进的性能。新的灵活的、多节点的、不同种类的流量“网络模拟器”将以非常适中的成本为中国研究人员以及所属机构和行业提供急需的面向网络的测试能力。这一优势源于TOAN不是为超高传输速度和数据吞吐量而设计的，而是为了演示和测试网络功能而设计的。它将重点放在一个透明的聚合域上，该域具有到住宅接入区域和数据中心、到相邻域以及到核心/主干的接口。TOAN的智能优势在于其独特的方法，将目前分散在多个试验点的功能(传输、处理、监控)结合在一个统一的实验室式、灵活、负担得起和可管理的环境中。已经与CIAN工业分支机构合作得出了用于仿真多节点聚合网络的典型规范，由此已经设置了相关目标，例如在需要自适应损伤补偿和/或损伤感知的交换和路由的情况下，在不同传输介质上的6节点/40G数据速率/200千米链路长度/400千米环长。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。Cian制造的设备的损伤感知跨域流量工程和功能测试，涉及级联能力和网络稳定性，仅提及Cian工业附属公司建议Cian实施的几个功能。这种端到端的网络拓扑将允许在动态网络设置中实现损害补偿和交换的各种权衡的实验。拟议的新试验台的更广泛的影响有三个方面：(A)工程研究：提供网络功能仿真的较低层光网络平台的独特性，而不是传输段的一维级联或各种处理任务的孤立演示。(B)行业合作：根据现场访问小组的要求，TOAN将进一步促进与行业的合作(匹配的行业贡献表明有兴趣)。(C)本科教育：该试验台将用于建立一个为期一学期的研讨会式的“开放实验室”，以吸引即将入学的工程一年级学生学习光通信，使他们熟悉高级网络测试，并招收最优秀的学生作为未来的CIAN本科生研究助理。随着新子系统的引入，试验台的功能将随着时间的推移而增加，从而提供更多监视和控制各种网络配置的能力。总体而言，该试验台将加快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.
