High Performance Networks
• vBNS – National Science Foundation High Performance
Connections Program
• Abilene – University Corporation for Advanced Internet
Development / Internet2
• Next Generation Internet– various federal agency networks (NREN, ESNet, DREN)
• Something New– not really sure yet, but there will be something after
vBNS & Abilene for Research and Education

The National Laboratory forApplied Network Research
• Established in 1995, as cooperative agreement with three sites, SDSC, NCSA, PSC
• Initially focused on the design, development and deployment of the NSF/MCI very high performance Backbone Network Service (vBNS)
• Established a new level of networking capability to support research
• Evolved to provide services to maintain, operate and support the use of the vBNS, Abilene and other high-performance networks.
• Recently provided direct support to researchers by leveraging the use of distributed resources.

National Laboratory forApplied Network Research
• Engineering Services (CMU/PSC)– Assist in the establishment and use of high-performance
network connections (vBNS and Abilene) – Help optimize overall end-to-end performance– Provide information, training, and tools to manage high
performance networks• The Measurement and Network Analysis team
(UCSD/SDSC)– Improving our understanding of service models, service metrics,
and tool requirements– Searching for macro-level insights into high performance
internetworking• The Distributed Applications Support team
(UIUC/NCSA)– support users and applications developers– develop an Applications Clearinghouse– develop training materials and documentation

The National Technology Grid
• Networks – high performance network services
• Computational Resources – supercomputers, clusters, distributed
computing resources
• Communications Resources– Wired, wireless, web-based, sync & async
• Other Services– Remotely controlled research equipment– Immersive environments

The DAST Clearinghouse
• Advanced Applications Clearinghouse– Develop a data base of applications &
people that use vBNS and Abilene– Identify “affinity groups” of users by
discipline or shared technologies– Explore concept of “User Services” for
advanced networks and computational resources
– Design a process / product that can be generalized or reproduced for use by other “affinity groups”

Applications & Middleware
Green slime of policy & non-technical stuff that get in the way of making technology work.
Projects Middleware
• Scientific Visualization• Data Mining• TeleImmersion• Remote Instrumentation• Distance Learning• Video Conferencing• Distributed Computing• email• Web Browsing• Resource discovery• Collaboration• etc., etc., etc.
Networks
• Pipes• Architecture• Operation Centers• Security• Protocols• Engineering• etc., etc., etc.

Current State
• Online since September 1999– With assistance of NCSA C&C Information
Resources Group
• 980+ Projects– Project = “meritorious application,” research
or educational activity using resources
• 180+ Resources– Resouce = applications, hardware, network,
software, systems (composite of other parts)
• Search / Query URL– http://dast.nlanr.net/Clearinghouse/Query.

The Klearinghouse
• Next the Knowledge thing….– People to data / information – kBase
• Information about collections (e.g., data, meta-data, and others).
– People to People – kSpace• Information about computer mediated
communications tools / applications /collaboratories
– People to Tools of their work – kTools• Information about resources / applications used
by specific disciplines (e.g., Biologist Workbench, TeleMedicine, Sloan Digital Sky Survey).

Visual Model
14 July 2000 TWIST 2000 -- [email protected]
Process Model
14 July 2000 TWIST 2000 -- [email protected]
Issues
• Management of collection– Requires proactive human intervention
• Information resources autonomous and diverse
• Priority placed on work at hand not planning for future
• Who owns the problem?– Research lab, campus, professional org, ???

User Support Services
• What are the new models?– (De) Centralized or at least Distributed
• What works? – New model, Old model– Look to other communities (e.g., special libraries,
commercial help desks, commercial industries)
• What services?– Help desk– Training– Research & Development– Technology Transfer– Business practices– Documentation
