NSF EXTENDS NLANR AWARD FOR ANOTHER YEAR

January 12, 2001

SCIENCE AND ENGINEERING NEWS

The National Science Foundation has awarded $2.5 million to the National Laboratory for Applied Network Research (NLANR) to continue technical, engineering, and traffic analysis support to the high-performance networking and applications communities. This extends by one year NLANR’s original three-year cooperative agreement to provide networking support to universities and institutions connected to the nation’s high-performance backbone networks.

“Since being formed in 1997, NLANR has excelled at developing tools, providing training, supporting individual applications and offering network-usage information to researchers in computer science and scientific computing,” said Thomas Greene, NSF senior program director in the Advanced Networking Infrastructure program. “These activities contribute to what is becoming known as Cyber-Infrastructure, which incorporates more varied resources than just connectivity or computational power. NSF is pleased to support this and similar projects of such quality and focus.”

NLANR was initially created to provide network engineering support for the vBNS connections at the five original NSF-funded supercomputing centers. The group has evolved into three teams that provide a range of support and services to the broad high-performance networking and applications community.

During the past three years, NLANR has focused on assisting the more than 170 NSF-funded High-Performance Connections Sites in connecting to and using the high-performance research network backbones, services, and technologies. It has developed software tools to assist scientific users and network administrators, and has developed a network analysis infrastructure to help keep the networks running smoothly and efficiently. NLANR staff work with individual researchers and staff at small-to mid-sized campuses and at commercial vendor and service providers resulting in a broader impact on the networking and application communities.

The award, which will be divided between the three program teams, is an amendment to the primary award made in 1997. The three NLANR program areas are:

*The Distributed Applications Support team at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign. This team helps researchers who use resources interconnected by high performance networks maximize the performance of their distributed applications and solve networking problems. The team has worked closely with a number of research groups on applications ranging from the computationally intensive, to distributed data mining and shared multimedia collaborative environments. Staff have also given training sessions around the country and demonstrated NLANR-developed tools such as Iperf, Netlog, and Viznet. Over the next year, the distributed applications support team will continue in an enabling support role and work on advancing the development of tools useful to both the applications developers and network engineering communities.

*The Engineering Services Team, a collaboration between the Pittsburgh Supercomputing Center and the National Center for Atmospheric Research. This team provides advanced network engineering support to the high-performance networking community. During the coming year, the engineering services team will focus on issues associated with integrating, supporting and using advanced network services in the gigapop and campus infrastructure as well as optimizing end-to-end performance for applications over this integrated environment. NLANR network engineers also develop tools, such as Traffic Analysis and Automatic Diagnosis (TAAD) to help improve network performance. The team offers the NLANR On-Site program that provides courseware and hands-on training tailored for network engineers and disciplinary scientists.

*The Measurement and Network Analysis Team, based at the San Diego Supercomputer Center. This team has created a network analysis infrastructure by deploying both active and passive measurement devices at more than 100 locations across the networks, gathering statistics, and analyzing and visualizing traffic patterns. Working with performance and flow measurements acquired at high-performance computing sites, the staff use packet information to develop and extend systemic service models and metrics of the networks. They also develop tools for network analysis and visualizations and support outside research activities. The statistical information and passive network traffic traces they gather and the software they develop are available to the public.

The NSF’s Advanced Networking Infrastructure and Research (ANIR) Division supports research in the technical areas relevant to understanding the global information infrastructure, lays the basis for future advancements, and develops and enables the use of experimental advanced networks in broad support of the research and education community. For more information about the NLANR award or the ANIR Division, see http://www.cise.nsf.gov/anir/.

The National Laboratory for Applied Network Research is an NSF-supported collaboration to provide technical, engineering and traffic analysis support for NSF’s High Performance Connections sites and the nation’s high-performance network infrastructure. NLANR members are: National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign, Pittsburgh Supercomputing Center, the National Center for Atmospheric Research, and the San Diego Supercomputer Center.
