National Laboratory for Applied Networking Research (NLANR):Distributed Applications Support Team (DAST)

摘要：NCR9725292国家应用网络研究实验室(NLANR)：分布式应用支持团队(DAST)1995年，NSF授予国家应用网络研究实验室(NLANR)合作协议，为超级计算中心的vBNS连接提供工程、技术支持和协调。NLANR团队活动的目的是(I)对NSFvBN进行充分的测试、利用和测量，以确保其整体表现处于可接受的水平；(Ii)促进将在NSFvBN上进行的实验；以及(Iii)协调各中心之间的支持活动。它还为NSFvBN的一般使用提供了有限的工程和技术支持，并协调这些活动，并促进在超级计算中心开发一支熟练的分布式网络工程团队，对NSFvBN及其性能能力和高性能应用程序的使用有透彻的了解。NSFvBNS最近开始扩展，以鼓励将其用作“前沿但稳定的”平台，使更广泛的学术研究界能够开发和使用高性能应用程序，这要求NLANR原有的活动必须大幅扩展，以涵盖对新用户、站点和应用程序的支持，以及对扩展后的网络的持续测量和测试。这种扩展的需要将NLANR活动划分为三个职能领域的单独奖项：NLANR：分布式应用支持团队(DAST)，位于伊利诺伊大学香槟分校，旨在帮助高性能应用的最终用户实现其应用性能的最大化；NLANR：位于卡内基-梅隆大学的国家网络工程中心(NCNE)，旨在协助高性能连接校园优化其网络工程和连接；以及位于加州大学圣地亚哥分校的NLANR：测量和运营分析小组(MOAT)，旨在测量和优化NSFvBN和互联网络的性能和使用。这三项努力将继续相互密切协调，并将与国家森林和粮食安全网络密切协调。该协议规定了NLANR：分布式应用支持团队(DAST)，它建立在NLANR活动的基础上，并利用NCSA在支持两个高性能网络的用户方面的经验(通过NLANR、IWAY、BLACA等)。和复杂的计算环境(通过为数千名用户服务的NCSA用户支持结构)。DAST将安排网络和软件工程师与用户直接接触，编写培训材料和主办讲习班，以促进将支持应用程序的专门知识转移到其机构的高性能连接终端用户和用户服务组织。DAST为具有高性能应用程序的高性能连接奖励站点用户建立了一个中央帮助台，以协调与高性能连接计划相关的vBNS和其他网络相关问题的路由和解决方案。

ABSTRACT: NCR9725292 National Laboratory for Applied Networking Research (NLANR): Distributed Applications Support Team (DAST) In 1995, NSF awarded a cooperative agreement for a National Laboratory for Applied Networking Research (NLANR) providing for engineering, technical support and coordination of the vBNS connections at the supercomputing centers. The purposes of this NLANR team activity were (i) to provide sufficient testing, utilization and measurement of the NSFvBNS to insure that its overall performance was at acceptable levels, (ii) to facilitate the experiments to be performed on the NSFvBNS, and (iii) to provide for the coordination of support activities among the centers. It also provided limited engineering and technical support for general use of the NSFvBNS and provided for the coordination of such activities and facilitated the development at the supercomputing centers of a skilled and distributed network engineering team with a thorough knowledge of the NSFvBNS and its performance capabilities and use for high performance applications. The recently initiated expansion of the NSFvBNS to encourage its use as a "leading edge but stable" platform to enable the development and use of high performance applications by the broader academic research community requires that the original NLANR activities be significantly expanded to encompass support for new users, sites and applications as well as continued measurement and testing of an expanded network. The need for this expansion has defined the NLANR activity into separate awards for three functional areas: the NLANR: Distributed Applications Support Team (DAST), located at the University of Illinois at Urbana-Champaigne, aimed at assisting the end users of high-performance applications in maximizing the performance of their applications; the NLANR: National Center for Network Engineering (NCNE), located at Carnegie-Mellon University, aimed at assisting high performance connections campuses in optimizing their network engineeri ng and connectivity; and the NLANR: Measurement and Operational Analysis Team (MOAT), located at the University of California, San, Diego, aimed at measuring and optimizing performance and use of the NSFvBNS and interconnected networks. The three efforts will continue to be be closely coodinated with each other and with the NSFvBNS. The agreement provides for the NLANR: Distributed Applications Support Team (DAST) which builds on the NLANR activity and brings to bear NCSA's experience in supporting users of both high performance networks (through NLANR, IWAY, BLANCA, etc.) and complex computing environments (through the NCSA user support structure that serves several thousand users). DAST will place network and software engineers in direct contact with users, develop training materials and the host workshops to facilitate the transfer of expertise in supporting applications to the High Performance Connections end users and user service organizations at their institutions. DAST establishes a central help desk for High Performance Connection award site users with high performance applications to coordinate the routing and resolution of problems related to the vBNS and other networks associated with the High Performance Connections program.
