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.

由于多种原因，今天的互联网被严重过度供应，例如，以吸收流量突发、在发生故障时处理额外（重新路由）负载、以及用于长期流量增长而无需现场频繁升级。这种过度供应给互联网增加了大量的资本成本。ACTION项目通过根据网络资源利用情况动态调整其“光学高速公路”能力，使互联网能够适应不断变化的需要和需求。项目名称ACTION代表“Applications Coordinate through Transport Interfaces with Optical Networks”，这意味着互联网光高速公路的容量是一种时间可调的商品，可以通过专门设计的接口由应用程序智能控制。例如，部分光谱可以在交通量低的高速公路上释放，并在需要时重新分配给其他高速公路或关闭以节省能量。这种灵活的高速公路是通过将城域核心中的WDM（波分复用）灵活网格技术与园区/接入中的DSCM（数字副载波复用）技术相结合来实现的。ACTION研究活动将在日本千兆网络极端（JGN-X）测试平台上进行最终演示。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UVA工程多样性中心和UTDallas与CONACYT（墨西哥国家科学技术理事会）的长期关系招募妇女和代表性不足的少数民族。调查结果、文件、出版物链接和软件将通过维基网站传播。 所有开发的教学材料将在TeachEngineering.com上提供。
