EIN: Collaborative Research: Dynamic Resource Allocation via GMPLS Optical Networks

该提案的目的是为高端e-Science应用程序创建动态、确定性和可管理的端到端网络传输服务。这一服务能力将建立在IP基础设施的成功和覆盖范围之上，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来补充。该项目将创建一个支持通用多协议标签交换(GMPLS)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提供确定性网络资源。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，并将模拟基于区域间、国家甚至全球波长的研究和教育(R&Amp；E)网络的许多功能。与核心基础设施相连的是由协作机构校园基础设施划分出来的试验性园区网络。网络需求将由与应用团队成员的紧密集成推动。该项目的一个重要部分将是开发必要的软件组件，以解决尚未解决的全球多协议标签交换相关问题以及一系列实际的端到端问题。该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、代理信令服务以及对所请求的网络服务的授权/计费。NARB功能的架构将集成来自NSF中间件倡议(NMI)计划的新兴高级服务和网格服务，特别是安全和高级调度服务。该项目包括与具体的电子科学应用支持设施进行合作，这些设施将适应并直接受益于实验基础设施。麻省理工学院干草堆天文台的电子甚长基线干涉测量(e-VLBI)项目将利用实验网络实时获取射电望远镜数据并将其关联起来，作为一项试点，以展示多个远程仪器的有效协调。南加州大学/ISI East、马里兰大学可视化和演示实验室和NASA戈达德太空飞行中心将合作使用这些资源，作为持续努力的一部分，以整合流媒体高清电视、访问网格节点和交互式远程3D可视化。该项目的智力优势包括极大地扩展了与动态光传送网智能管理相关的知识和技术。这将是必要的，以使更大的R&A；E社区实现其目前努力采购全国范围内的波长和光纤资源的最大利益。将通过区域大学的参与实现更广泛的影响，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，并让妇女和代表不足的少数群体作为实习生参与这些活动。

This purpose of the proposal is to create 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 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 wavelength based Research and Education (R&E) networks. Attached to the core infrastructure will be experimental campus networks carved out from collaborating institutional campus infrastructure. Network requirements will be driven by tight integration with application team members. An important 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 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 infrastructure. The electronic-Very Long Baseline Interferometry (e-VLBI) project from MIT Haystack Observatory will utilize the experimental 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 the resources as part of ongoing efforts to integrate streaming HDTV, Access Grid Nodes, and interactive remote 3D visualizations. The intellectual merit of this project includes greatly expanding the knowledge and technologies relating to intelligent 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.
