NeTS JUNO: Collaborative Research: ACTION: Applications Coordinating with Transport, IP, and Optical Networks

当今的互联网严重超配的原因有很多，例如，为了吸收流量突发、在故障发生时处理额外的(重新路由的)负载，以及在没有频繁现场升级的情况下实现长期流量增长。这种过度配置会显著增加互联网的资本成本。该行动项目使因特网能够根据网络资源利用情况动态调整其“光高速公路”能力，以适应不断变化的需要和需求。该项目名称ACTION代表“应用程序通过传输接口与光网络进行协调”，意味着互联网光高速公路的容量是一种时间可调的商品，可以由应用程序通过专门设计的接口进行智能控制。例如，部分频谱可以在交通量较低的高速公路上释放，或者重新分配到需要的其他高速公路上，或者关闭以节省能源。这种灵活的高速公路是通过将城域核心的WDM(波分复用)柔性网格技术与园区/接入的DSCM(数字副载波复用)技术相结合来实现的。行动研究活动将在日本千兆网络-极限(JGN-X)试验台上进行最后的演示。该行动项目将积极吸引本科生参加高级论文和设计项目，通过利用弗吉尼亚大学工程多样性中心和UTDallas与墨西哥国家科学和技术委员会(CONACYT)的长期关系，招募妇女和代表不足的少数群体。调查结果、文件、出版物和软件的链接将通过基于维基的网站传播。开发的所有教学材料将在TeachEngineering ering.com上提供。

Today's Internet is significantly over-provisioned for a number of reasons, e.g., to absorb traffic bursts, to handle the extra (rerouted) load when failures occur, and for long-term traffic growth without frequent upgrades in the field. This overprovisioning adds significant capital costs to the Internet. The ACTION project enables adaptation of the Internet to changing needs and demands by dynamically adjusting its "optical highway" capacities based on network resource utilization. The project name ACTION stands for "Applications Coordinate through Transport Interfaces with Optical Networks," implying that the capacity of the Internet optical highways is a time-adjustable commodity, which can be intelligently controlled by the applications via specially designed interfaces. For example, part of the optical spectrum can be freed on highways with low traffic volume and either reassigned to other highways where needed or switched off to conserve energy. Such flexible highways are achieved by combining WDM (Wavelength Division Multiplexing) Flexible Grid technology in the metro-core with DSCM (Digital Subcarrier Multiplexing) technology in the campus/access. The ACTION research activities will culminate in a final demonstration on the Japan Gigabit Network-extreme (JGN-X) test-bed. The ACTION project will actively engage undergraduate students in Senior Thesis and Design Projects, recruit women and under-represented minorities by leveraging the UVA Center for Diversity in Engineering and the UTDallas long-standing relationship with CONACYT (National Council for Science and Technology of Mexico). Findings, documents, links to publications and software will be disseminated through a wiki-based Web site. All instructional materials developed will be made available at TeachEngineering.com.
