National Laboratory for Applied Networking Research (NLANR):National Center for Network Engineering (NCNE)

摘要：应用网络研究国家实验室（NLANR）：国家网络工程中心（NCNE） 1995年，美国国家科学基金会（NSF）授予了一个应用网络研究国家实验室（NLANR）的合作协议，该实验室为超级计算中心的vBNS连接提供工程、技术支持和协调。NLANR团队活动的目的是(1)对NSFvBNS进行充分的测试、利用和测量，以确保其整体性能处于可接受的水平；(2)促进在NSFvBNS上进行的实验；(3)协调各中心之间的支持活动。它还为NSFvBNS的一般使用提供了有限的工程和技术支持，并提供了这些活动的协调，并促进了超级计算中心的技术和分布式网络工程团队的发展，这些团队对NSFvBNS及其性能能力和高性能应用程序的使用有透彻的了解。为了鼓励NSFvBNS作为一个“领先但稳定”的平台被广泛的学术研究社区开发和使用，NSFvBNS最近开始进行扩展，这就要求原有的NLANR活动得到显著扩展，以包括对新用户、站点和应用的支持，以及对扩展网络的持续测量和测试。这种扩展的需要将NLANR活动定义为三个功能领域的独立奖项：NLANR：分布式应用支持团队（DAST），位于伊利诺伊大学厄巴纳-香槟分校，旨在帮助高性能应用程序的最终用户最大化其应用程序的性能；NLANR：国家网络工程中心（NCNE），位于卡内基-梅隆大学，旨在帮助高性能连接校园优化其网络引擎和连接；以及位于加州大学圣地亚哥分校的NLANR：测量和操作分析小组（MOAT），旨在测量和优化NSFvBNS和互联网络的性能和使用。这三方面的努力将继续相互密切协调，并与NSFvBNS密切协调。该协议规定了NLANR：国家网络工程中心（NCNE），该中心建立在以前的NLANR活动和匹兹堡超级计算机中心卡内基梅隆大学网络工程人员在分析和支持与高性能网络活动相关的问题和特性方面的经验基础上。NCNE将安排网络工程师与高性能连接机构的校园网络人员直接接触，并将举办研讨会，以促进向这些机构的服务组织转移支持高性能网络的专业知识。NCNE为高性能连接奖励站点建立了一个中央帮助台，以支持和协助校园和其他本地服务组织解决与校园网相关的网络工程问题、与vBNS的连接以及与高性能连接计划相关的网络的其他工程问题。

ABSTRACT: NCR9720674 National Laboratory for Applied Networking Research (NLANR): National Center for Network Engineering (NCNE) 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 engine ering 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: National Center for Network Engineering (NCNE) which builds on the previous NLANR activity and the experience of Carnegie Mellon University's network engineering personnel at the Pittsburgh Supercomputer Center in analyzing and supporting the problems and peculiarities associated with high performance networking activities. NCNE will place network engineers in direct contact with campus networking personnel at High Performance Connections inatitutions andwill host workshops to facilitate the transfer of expertise supporting high performance networking to service organizations at those institutions. NCNE establishes a central help desk for High Performance Connection award sites to support and assist campus and other local service organizations in the resolution of network engineering problems related to campus networks, their connections to the vBNS and other engineering issues relevant to networks associated with the High Performance Connections program.
