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

今天的互联网由于许多原因而明显供应过剩，例如，吸收突发流量，在发生故障时处理额外的（重路由）负载，以及在没有频繁升级的情况下长期流量增长。这种过度供应给Internet增加了显著的资本成本。ACTION项目通过根据网络资源利用率动态调整其“光高速公路”容量，使互联网能够适应不断变化的需求。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”，这意味着互联网光高速公路的容量是一种时间可调节的商品，可以通过特殊设计的接口由应用程序智能控制。例如，在交通量较少的高速公路上，可以释放部分光谱，在需要时重新分配给其他高速公路，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中的WDM（波分复用）柔性网格技术与校园/接入中的DSCM（数字子载波复用）技术相结合来实现的。ACTION研究活动最终将在日本千兆网络极限（JGN-X）测试台上进行演示。ACTION项目将积极吸引本科生参与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达拉斯大学与墨西哥国家科学技术委员会的长期合作关系，招募女性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一个以维基为基础的网站传播。所有开发的教学材料将在TeachEngineering.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.
