The objective of the Dynamic Resource Allocation via GMPLS Optical Networks (DRAGON) Project is tocreate dynamic, deterministic, and manageable end-to-end network transport services for high-end e-Science applications. This service capability will build on the success and reach of the IP infrastructure, and will complement it with deterministic end-to-end multi-protocol services spanning multiple administrative domains and a variety of conventional campus network technologies. The DRAGON project will create a Generalized MultiProtocol Label Switching (GMPLS) capable optical core network. Optical transport and switching equipment acting as Label Switching Routers (LSRs) will provide deterministic network resources at the packet, wavelength, and fiber cross connect levels. The all-optical capabilities proposed for this core network will be based on connection and resource management mechanisms defined in GMPLS and will model many of the functions of an inter-regional, national, or even global wavelengthbased Research and Education (R&E) networks. Attached to the core infrastructure will be experimental campus networks carved out from collaborating institutional campus infrastructure. The institutional Experimental Networks (ExNets) will provide the DRAGON Project with both an overall multi-domain environment and representative heterogeneous network technologies that must be handled in a real world end-to-end vision. Network requirements will be driven by tight integration with application team members.A critical part of the project will be the development of the necessary software components to address unresolved GMPLS related issues as well as a host of practical end-to-end issues. The DRAGON architecture describes a Network Aware Resource Broker (NARB) that will peer with Interior Gateway Protocol/Exterior Gateway Protocol (IGP/EGP) routing protocols to advertise inter-domain service capabilities, perform inter-domain path computation, resource allocation, scheduling, provisioning, proxy signaling services, and authorization/accounting for the requested network services. The architecture of the NARB function will integrate emerging advanced services from the NSF Middleware Initiative (NMI) program and Grid services, particularly for security and advanced scheduling. The project includes collaboration with specific e-Science applications support facilities that will be adapted to and directly benefit from the experimental DRAGON infrastructure. The electronic-Very Long Baseline Interferometry (e-VLBI) project from MIT Haystack Observatory will utilize the DRAGON network to acquire and correlate radio-telescope data in real time as a pilot to demonstrate effective coordination of multiple remote instruments. USC/ISI East, University of Maryland Visualization and Presentation Lab, and NASA Goddard Space Flight Center will collaborate to use DRAGON resources as part of ongoing efforts to integrate streaming HDTV, Access Grid Nodes, and interactive remote 3D visualizations. This project is a collaboration of Mid-Atlantic Crossroads, University of Southern California Information Sciences Institute, George Mason University, University of Maryland, NASA Goddard Space Flight Center, Massachusetts Institute of Technology Haystack Observatory. Movaz Networks will be a key partner by providing GMPLS enabled wavelength selective switches for the core, and will be closely involved with the inter-domain routing aspects of the NARB development via their software development team in Northern Virginia.The intellectual merit of this project includes greatly expanding the knowledge and technologies relating tointelligent management of dynamic optical transport networks. This will be necessary in order for the larger R&E community to realize maximum benefits from its current efforts to procure a national footprint of lambda and fiber resources. Broader impacts will be realized via the participation of regional universities that will directly enhance the research and education infrastructure and provide educational opportunities for undergraduate and graduate students as well as involve women and underrepresented minorities as interns in the activities. The project duration is expected to be four years. At the end of the first year, DRAGON project will demonstrate an initial capability set of a) core GMPLS/Optical dynamic provisioning, b) inter-domain service routing, and c) at least two e-Science applications able to utilize the end-to-end service provisioning. By year 3, DRAGON expects to have a stable inter-domain advertising and routing function, stable provisioning, authorization and accounting, and a simplified interconnection API. In years 4 a major focus will be on increasing application usage, integration with other regional advanced networks, and developing plans for migration to production network status.

通过GMPLS光网络的动态资源分配（DRAGON）项目的目标是为高端e-Science应用创建动态、确定性和可管理的端到端网络传输服务。这种服务能力将建立在IP基础设施的成功和覆盖范围的基础上，并将通过跨越多个管理域和各种传统园区网络技术的确定性端到端多协议服务对其进行补充。 DRAGON项目将创建一个具有通用多协议标签交换（GMPLS）能力的光核心网络。作为标签交换路由器（LSR）的光传输和交换设备将在分组、波长和光纤交叉连接级别上提供确定性的网络资源。为该核心网络提出的全光能力将基于GMPLS中定义的连接和资源管理机制，并将模拟区域间、国家甚至全球基于波长的研究和教育（RE）网络的许多功能。附属于核心基础设施的将是从协作机构校园基础设施中分割出来的实验性校园网络。机构实验网络（ExNets）将为Dragon项目提供一个整体的多域环境和代表性的异构网络技术，这些技术必须在真实的世界端到端的视野中处理。网络需求将通过与应用团队成员的紧密集成来驱动。该项目的一个关键部分将是开发必要的软件组件，以解决未解决的GMPLS相关问题以及一系列实际的端到端问题。DRAGON体系结构描述了网络感知资源代理（NARB），其将与内部网关协议/外部网关协议（IGP/EGP）路由协议对等，以通告域间服务能力，执行域间路径计算、资源分配、调度、供应、代理信令服务以及所请求的网络服务的授权/计费。NARB功能的体系结构将集成来自NSF中间件计划（NMI）和网格服务的新兴高级服务，特别是安全和高级调度。该项目包括与特定的电子科学应用支持设施的合作，这些设施将适应并直接受益于实验性的DRAGON基础设施。麻省理工学院Haystack天文台的电子甚长基线干涉测量（e-VLBI）项目将利用Dragon网络实时获取和关联射电望远镜数据，作为试点，展示多个远程仪器的有效协调。真实的相关数据。USC/ISI East、马里兰州大学可视化和演示实验室以及NASA戈达德太空飞行中心将合作使用DRAGON资源，作为正在进行的集成流媒体HDTV、访问网格节点和交互式远程3D可视化的努力的一部分。 该项目是中大西洋十字路口、南加州大学信息科学研究所、乔治梅森大学、马里兰州大学、美国航天局戈达德空间飞行中心、马萨诸塞州理工学院干草堆天文台的合作项目。Movaz网络公司将成为一个关键的合作伙伴，为核心提供支持GMPLS的波长选择交换机，并将通过其在北方弗吉尼亚州的软件开发团队密切参与NARB开发的域间路由方面。这将是必要的，以便更大的R E社区从其目前的努力中实现最大的利益，以获得全国范围的λ和纤维资源。通过区域大学的参与，将产生更广泛的影响，这些大学将直接加强研究和教育基础设施，为本科生和研究生提供教育机会，并让妇女和代表人数不足的少数群体作为实习生参与活动。项目期限预计为四年。在第一年年底，Dragon项目将展示以下初始功能集：a）核心GMPLS/光动态配置，B）域间服务路由，以及c）至少两个能够利用端到端的电子科学应用程序服务提供。到第3年，Dragon预计将拥有稳定的域间广告和路由功能，稳定的配置，授权和计费，以及简化的互连API。第4年的主要重点将是增加应用程序的使用，与其他区域高级网络的集成，以及制定迁移到生产网络状态的计划。
